A, AB, D or All Three? Pick Your Amp!

Amplifiers, such a range but which is right for you? I’d like to discuss amplifier types and applications.

As a Four Master, Car and Home Stereo are recognised as one of the leading car audio installers in the country. Our knowledge and experience mean that we are ideally placed to choose the right equipment and install it to the highest standard.  We offer a no pressure approach and are happy to offer advice on choosing the right equipment; just recently I had a great conversation over Facebook with an enthusiast in Australia over the benefits of the magnificent Rainbow Profi speakers.

Commonly I am asked “how many Watts is it?” but there is so much more to an amplifier than that. In reality, the Watts figure is often not the most useful specification when choosing between amplifiers. True it gives a simple indication of power but all too often that figure is heavily massaged to look higher. I have tested some so-called 3000W amplifiers to discover that they only made 200W at the terminals into a speaker load. Still an impressive output but certainly not 3000W as claimed.

But I digress; we are looking today at amplifier types and their uses. There are three types of amplifiers in main use today they are classed as A, AB and D. Although they all have the same purpose there are some fundamental differences between them that make them suit different applications.

At the heart of an amplifier are the power transistors, these are responsible for taking a small signal and making it larger, the classification describes how the transistors are used. Of course, there is a massive range of qualities and performance variations related to each type but we will stick to classes.

Class A, a typical sound wave.

As we know, Sound is an oscillating wave. This wave has a positive and a negative component but is symmetrical about the ‘t’ axis. So all we need is one big transistor that can amplify the whole signal to whatever power we want right? Well yes and this is the ideal solution for sonic accuracy; the high output signal is an exact copy of the small input signal. The best amplifiers I have ever heard have all been A class with a sound that is open, transparent and simply a joy to listen to.

The magnificent Audison Thesis Venti

However, all this purity comes at a price; huge power consumption. Those massive transistors are switched on all the time regardless of whether there is a signal there or not or how loud it’s playing. This means heat and lots of it which has to be dissipated. So we need massive power supplies and large heatsinks which make the amplifier large and somewhat inefficient, typically around 20%. That’s why we need to use such large power cable!

So how do we get better efficiency? Class AB.

 

There are many considerations here but in very simplistic terms it is possible to use one transistor to amplify the top half of the wave and another matched transistor to amplify the bottom half. This means that smaller transistors can be used and they are only on for half the time leading to efficiencies of 50 to 70%. This means less heat and smaller power supplies which help to keep the cost down.

The JL Audio JX360, a mainstay of many audio systems

There are some drawbacks to class AB, principally of which is crossover distortion.

As a matched pair of transistors has to amplify the whole wave it is essential that they turn off and on at exactly the right moment (the class B part). Imagine two people writing the letter S where one person only writes one-half and the other person completes it, there is bound to be a little error. The same is true in the amplifier leading to a very slight distortion of the output wave but in truth, modern design can almost eliminate this meaning we can have a really great sounding amp that is pretty efficient. This has meant that AB design has dominated the market for decades.

The highest efficiency is class D.
Let’s get something straight, D does not stand for digital. Class D is just another design type, a really clever one. This design uses pulse width modulation to generate the amplified output which involves switching the output transistors on and off at a very high rate typically around 300 kHz. This High switching frequency means any noise is well above our audible range and the PWM leads to astonishing efficiencies of around 95% or higher. So, at last, we have a very high power, high quality and very efficient amplifier. It is fair to say that most mainstream car amplifiers today are D class as they are smaller, lighter and generate less heat than their A or AB counterparts.

The JL Audio XD400.4, small but powerful

As with almost everything, there has to be a downside and with D class their Achilles heel is radio interference. The switching frequency mentioned might not be audible but it can do a fine job of broadcasting in the FM radio range. This can lead to reduced radio reception at certain frequencies, of course, modern design does mitigate the problem but nevertheless, it can still be an issue.

So to sum up, Class A for the best possible sound (ideal for tweeters), Class AB for improved efficiency (ideal for midrange) and Class D for maximum power from the smallest chassis (ideal for subwoofers). Wouldn’t it be great if there was an amplifier with all three? Well, there is and it is called the 5.1K from Audison.

 

The superb and versatile Audison 5.1K

This is one of my all-time favourite amplifiers and it is the amp that powers my own personal system. The detail of the class A front stage is phenomenal while the AB class mid-stage offers an amazing amount of punch. The D class sub stage has enough power to rattle the windows but offers a fidelity that allows a seamless blend with the rest of the audio stage. This unit never fails to impress and is not too big to make it impossible to fit. It does get hot if driven hard but does not require special cooling if mounted sensibly.

 

If you would like to hear what the 5.1K can do then please feel free to call into our shop on Sunderland Street in Macclesfield and I would be pleased to demonstrate it in our Discovery or on the demonstration stand in store. If you would like any more information on amplifiers in general please call me on 01625 432707.

 

 

Gain An Advantage: Amplifier

Anyone who has dabbled in car audio will have come across an amplifier at some point. They come in many shapes, sizes, and outputs but from the cheapest eBay special to eye wateringly expensive European exotica they all have one purpose, to get the musical signal to the speakers. The amplifier is, therefore, sat between the CD player and the speakers accepting the low-level input signal and converting it to a high power speaker output. I don’t want to get too bogged down in technicalities but let’s discuss the different types available and the controls we are given.

The JL Audio RD900.5 is a perfect example. This 5 channel, D class amplifier is capable of running a complete car audio system with front speakers, rear speakers, and a subwoofer. Alternatively, it could run a pair of front speakers bridged for enormous power plus a subwoofer once again. So, the RD900.5 is a very high performance, a flexible amplifier with a pretty small footprint making it easy to install.

The input stage is on the far left of this amplifier and comprises the usual red and white RCA connectors. There are 3 pairs that equate to the front, rear and sub input. Above these are three switches that allow for hi or low-level input, auto turn on mode and input channel selection (2, 4 or 6). Not all amplifiers are equipped with these selectors but these add to the RD900.5 flexibility.

The next stage is what interests us here, the frequency filter and the gain controls. The RD 900.5 is nonsymmetrical meaning that all channels are not identical. Channels 1 to 4 are for main speakers while 5 and 6 are for subwoofers. Therefore there is a variable high pass filter for 1 to 4 and a low pass filter for 5 and 6.

What is the filter for you ask? It is used to remove frequencies that are not required by the speaker on that channel. If we know we have a subwoofer fitted then it makes no sense to send the very low frequencies to the door speakers. Sub frequencies require a speaker cone to move a great distance and most door speakers simply cannot achieve this without distortion, I’m sure you have all heard a speaker trying too hard causing the classic ‘burping’ sound. In extreme cases, the speaker coil can be heard crashing into the back plate creating a clapping noise. Either situation is undesirable so to prevent these from occurring the frequency filter is applied to restrict the low tones.

The cutoff frequency is variable to suit different speakers and installations and setting it correctly requires the use of a signal generator. If you do not have access to one of these then it is possible to do roughly by ear, simply play music and slowly raise the filter frequency until there are no very low sounds in the speaker. The result will be a much clearer sound with no distortion. The mid definition should be greatly improved meaning vocals will cut through better. Typically the filter control is graduated and a very rough initial setting for a typical door speaker would be around 80Hz but you should experiment either side of this to find the best setting.

The subwoofer (low-pass) filter is the opposite of the high pass filter as it removes the higher frequencies sent to the sub. This ensures it only gets useful frequencies and we do not waste amplifier energy trying to make it play the higher tones.

Again the cutoff frequency is variable but what we want is to blend the sub with the main speakers so it is important to find a filter point that complements the high pass filter for the speakers.

So now we come to the input sensitivity, perhaps one of the most misunderstood controls. First and foremost it is not a volume control. Sure, it does increase the volume as you turn it but that does not mean it is increasing the amplifier power. Let’s consider what an amplifier is doing, it is taking a small signal and making it bigger. That signal is very dynamic meaning it is made up of loud and quiet parts, an extreme example could be Tchaikovsky’s 1812 Overture. Not something we listen to every day but it serves our example very well. If you are not familiar with the piece it starts very quietly and builds to a crescendo of orchestra and cannons. A more modern piece would be Warriors Dance by Prodigy but with fewer cannons!

The most important thing to consider when setting the sensitivity is that the amplifier only has a finite amount of power, let’s say 100Watts. That is represented by the upper dotted line on the graphs above. Our goal is to get the maximum, undistorted output.

If we look at a typical input sound wave it is obvious that there are loud and quiet parts. As we stated the amplifier is there to make this signal louder. Now let’s add the maximum amplifier power to the input signal graph.

As we increase the sensitivity we increase the size of the input signal at the input stage to the amplifier and remember there is a finite amount of power available. So what happens if we go too far?

As can be seen the nice smooth curves at the top and bottom of the loud spikes have been flattened which is clipped distortion. So yes we have a loud sound but it will be fuzzy and unpleasant. It will also damage speakers as the flat tops of the wave are a DC signal that will only induce heat into the voice coils. So if we take our example, the 1812 Overture, with the sensitivity set as above the quiet passages will sound good but the loud sections will be badly distorted and this will get worse the louder we play it.

For the best sound and maximum output, it is imperative that the loudest sounds are not clipped. Normally this would be set up with an oscilloscope but it can also be done with a voltmeter by measuring the output for maximum unclipped voltage as long as you know the true output power.

Fortunately, the JL Audio RD amplifiers have a brilliant feature, a clip indicator. This will light up if the signal is distorted by over ambitious sensitivity meaning setting up is made much easier.

At Car and Home Stereo, we want all our installations to give the best possible sound and that is why we carefully set up each and every one.

If you would like to have your system checked for any problems and to find solutions to these we would love to measure your car using our state of the art test equipment. These can highlight deficiencies in the sound stage that are difficult to locate just by listening.

As usual, I have run out of space so I’ll leave amplifier types and their best application for another time. But please don’t hesitate to call on 01625 432707 if you have any questions.

Why Does Installation Matter?

At Car and Home Stereo we have been installing exceptional car audio for over 40 years, in fact, when we started there were barely the beginnings of in-car entertainment. Over those years we have seen a tremendous amount of change in the products we use to create outstanding audio experiences. From 8 track cartridge to CD to full digital audio, graphic equalisers to digital signal processors and all the other innovations that have come along we have embraced and utilised these to realise the best possible sound for our customers.

All these fabulous products are available to everybody, there has never been so much choice but all this technology will not guarantee a great sound. That will only be possible with the correct installation and careful setup. Many times I have had a car in that has had a lot of money spent on it yet still sounds bad. From buzzing door panels to downright dangerous wiring I’ve seen it all. Usually from DIY installations but not always. It’s not necessarily the fault of the equipment but rather a combination of poor choice and skimped installation.

It is true that the majority of my work is completely invisible but makes such a massive difference to either the finished sound or the reliability of the whole system.  Application of sound deadening material inside doors will improve the acoustic performance, soldering all connections may take longer but will improve reliability, looming cable runs with fleece tape is expensive but will eliminate any cable rattles and retain the OE look.

It is also important that equipment and wiring are installed to the highest standards to maintain vehicle warranties and safety standards. I have seen microphone cables wrapped around airbags, power cables attached to car batteries without a fuse and any amount of speaker wires dangling over brake pedals. At Car and Home Stereo, we take installation very seriously and we never rush. The best results are not achieved by racing to finish and I would rather spend an extra hour or two to get the best possible sound. After all, you would want your £1000 Rainbow speakers to sound their best.

Of course the same care and attention is applied whether we install top of the range JL Audio speakers or entry level Audison upgrades and in fact, the performance boost from proper door treatment at the lower price range is more apparent.

We will always recommend appropriate enhancements and best installation practices are rigorously followed which may take a little longer and cost a little more but will ultimately lead to a far better sound and is that not what we all really want?

Say Hello To The Future!

JL Audio are a renowned American manufacturer of the highest quality subwoofers, amplifiers and speakers. Some of our best sounding installs have been based around JL Audio products and it is true to say that there is something for everyone within the range.

I was lucky enough to attend a training day with JL Audio’s head of training, Steve Turrisi in March 2017 where, without exaggeration, I was shown the future of car audio. This year JL are launching a fabulous new range of products so let me describe what I was shown.

In June we will see a new entry level speaker range designated C1. These look set to clean up on the simple speaker upgrade market. They are robust, great sounding and very easy to fit as they come with installation collars to cater for different vehicle apertures.

 

 

I am sure I will be fitting a lot of these in the near future.

As mentioned there will also be a new ultra high-end speaker set, the C7. This speaker has been designed from the ground up to be the absolute best. Drawing from JL Audio’s many years of experience this will be a milestone in audio performance. It will not be cheap but the best never is.

Expect a price tag in excess of £2000 for these magnificent drivers but I am sure we will not be short of takers when these launch in summer 2017.

Already available are the new RD series of amplifiers which fill the gap between JX and XD. Boasting huge power output from a small chassis I have installed quite a few now and they are extremely impressive.

The RD amps are extremely well priced for the level of performance they deliver, the build quality is amazing and of course, they have the legendary JL sound. Available in mono, 2 channel, 4 channel and the incredible 5 channel every application is catered for.

As if this wasn’t enough I’ve saved the best till last. Available now are the stars of the show. JL Audio’s new line of digital processors the FiX and TwK.

With these products, we will no longer have to endure the sound supplied by factory head units that cannot be swapped out. The BMW, Ford, Audi and VW factory radios can be made to sound amazing. Couple this output to a great amp and speakers and there are no limits to how good your car could sound. This is thanks to the amazing TuN software developed by JL and an installers dream come true.

As can be seen, the software gives me complete control over every aspect of the audio system. There is nowhere near enough room here to describe all the features but trust me, this is a game changer. Car audio will now take the next great performance leap.

For details of all these great new products call me on 01625 432707 or better still call into our shop on Sunderland Street in Macclesfield.

Practicing Safe Sound

There are many ways to upgrade your car audio system and let’s face it, most cars need it. I’m looking at you BMW, VW and Porsche in particular! It is not always possible to upgrade the head unit but it is always possible to improve the speakers. At Car and Home Stereo, we carry speakers by JL Audio, Audison, Hertz, Rainbow and others. This means we can choose the right speaker to suit the car and the customer. We will carefully install your speakers with custom built collars and fittings as well as add sound deadening in the door to improve its acoustic properties. The end result will be a vastly better sound without any cosmetic changes to your car.

And that is where we are finished but before you leave, a word of warning. Please take the time to run your new speakers in. The running in period varies for different speakers but generally, we recommend around 10 hours play time. Running in means keeping the volume at a sensible level without any large bass settings and we will always advise what should be the maximum volume for this period.

If this procedure is not followed your speakers may not fail but they will not reach their full potential, let me explain why.

A speaker is a transducer that converts electrical energy into sound and at the heart of the speaker is a coil of wire sitting inside a magnet. It is bright, shiny copper.

coil speakers good copper

It’s not necessary to know how it works but the important point is that when you pass electricity through a wire heat is generated and the higher the electrical current the more heat is generated. Now, this coil of wire is crucial to the accuracy of the speaker and it is protected by a thin coating of lacquer. This lacquer is quite soft when new and easily damaged by heat but if it is gently warmed over a number of hours the lacquer will harden.

I bet you can see where this is going! If a new speaker is subjected to a lot of power and played loud the voice coil lacquer will boil causing short circuits. Now while this will not necessarily cause the speaker to fail it will mean that the voice coil is not a single continuous wire which leads to a ‘lumpy’ effect within the magnetic gap. This, of course, means that the reproduction of sound is not linear and your investment will not reach its true performance capability. In extreme circumstances, the lacquer is burnt and expands into the magnetic gap which will cause a scratchy sound. These failures are non-reversible, cannot be repaired and are not covered under any warrantee.

So that is why we advise the running in period, to gently warm the voice coil lacquer causing it to cure. This hardened lacquer can now stand the heat of high power and your speakers will really perform as the designers intended.

I cannot overstate the importance of running in, a speaker is more likely to be damaged in the first few hours of use rather than over the rest of its life. At Car and Home Stereo, we want you to get the best possible sound from our expert installation so just hold back on the volume for a few hours, you’ll be glad you did.

 

Vehicle Specific Systems: BMW E90

This car is a firm favourite of ours especially in the M Sport however, the stock audio is nothing short of terrible. There is a distinct lack of any real bass and even with the optional stock tweeters there is no sparkle or liveliness in the sound. A lot of owners are unaware that there are bass speakers are located under the front seats as the low-frequency performance is so bad. There are of course many options to improve the audio but perhaps the simplest is to replace the speakers. The BMW speakers are a unique size and fitting a standard set can be difficult, fortunately, there are several companies now making BMW specific replacement speakers. Foremost amongst these are Rainbow, a German company specialising in some very high-end speakers.

The Il-c8.3 kit is suitable for all BMW E9x and F series and comes complete with all OE style connectors. All speakers will fit in the standard location with the minimum of modification. What’s more, all the original speakers can be re-installed when the car is sold or returned.

The difference between the Rainbow and the stock speakers is astonishing even without fitting an upgraded amplifier. The sound stage is better with vocals being presented cleanly, the mid range is much less confused and at last, there is a decent bass response. It is possible to just change the door speakers but I would highly recommend replacing the whole set.

Another popular vehicle with an underwhelming audio system is the VW Golf. Like the BMW the stock system has no sparkle and again a poor bass response. Once again Rainbow step in to provide a direct replacement speaker set, one for the VW Golf Mk5 and one for the Mk6. Available in three and two-way, this upgrade immediately lifts the whole audio soundstage to a new level. The kit comes with all fittings and collars required so it is possible to fit yourself if you wish.

Of course, you may be looking for a complete upgrade for your Golf Mk6 or 7 and here we can turn to the masters of car audio Audison. They have designed a specific system for this car that replaces the speakers as well as adding a custom tuned amplifier and a  super slim sub enclosure designed to seamlessly fit the car.

 

This system brings a whole new dimension to the audio system with a full digital signal processor that is built into the compact amplifier that sits discreetly under the seat. It has been developed from painstaking testing and tweaking to make sure that it both integrates perfectly with the stock car and provides the best possible sound. Again this kit comes complete with everything you will need to install it but unless you are comfortable removing the trim and panels from your car we would recommend letting us install it.

Of course, not all cars are covered with a ready made upgrade kit and this is where Car and Home Stereo can really help. Over the last thirty years, we have seen almost every type of vehicle and our comprehensive knowledge allows us to design and install audio systems that will delight. We strive to design systems that will blend perfectly with your car whatever your requirements may be. From the simplest speaker upgrade to a complete multimedia systems our aim is to put a big smile on your face every time you listen to it and that is what music should be about.

 

If you are ready to start your journey to better sound then please call Tim on 01625 432707 or better still call into our shop on Sunderland Street in Macclesfield for a chat and a demonstration of the best that car audio can be.

Demonstration of Distortion

An interesting situation occurred at Car and Home Stereo recently that I would like to share. It highlighted a phenomenon that is quite counter intuitive and led to some interesting discussions.

We have a demonstration Land Rover Discovery that has a simple, high quality audio system installed that is tuned to perfectly suit the interior acoustics. We always encourage our customers to sit in and experience it as it shows what can really be done with car audio. The amplifier that powers the system is the magnificent Audison 5.1K which develops a true 1650 Watts.

There is one pair of component Hertz Mille Legend speakers in the front doors and a Hertz Mille subwoofer in the rear.

A customer recently auditioned the system and we spent a good hour playing different types of music with a view to producing something similar in his car. He was completely blown away with the sound, couldn’t believe the clarity and how the sub blended perfectly with the whole system. And then he said ‘I love it, but it’s not very loud is it?’. In fact he reckoned his standard Ford system was louder!

Now I know just how loud our system is and the odd thing is that the cleaner the sound the less we perceive volume. Since we had some time I decided to run a little proof experiment with my customer’s car.

As part of our equipment set we have an industry standard spectrum analyser which is also equipped with an SPL meter. It was a simple task to set this up in the Discovery first and then the Ford to compare. As expected our Discovery hit 126dB easily, the Ford however struggled to hit 110dB. In real world terms this equates to a perceived doubling of power (a true doubling is 3dB but we don’t really hear it that way). The next test was the distortion level. By plugging an oscilloscope into the amplifier output we can measure the clipping levels. Unsurprisingly the Discovery registered less than 5 percent distortion at full volume as this was how it was set up. However the Ford reached 5 percent at a little over half volume and climbed to over 25 percent.

There is no arguing with the figures so what is going on? Simply that the higher  distortion levels were being registered as unpleasantly loud and our brains are trying to get us to turn it down! Distortion is the quickest way to destroy a speaker or indeed your hearing.

At Car an Home Stereo we value our customers and hope to be providing high quality audio systems for many years. A distorted sound system will very quickly do serious harm to our hearing and that is why we only choose the best equipment and like to carefully set these up to give the best possible sound. Brands such as JL Audio, Audison, Hertz and Dynamat may not be the cheapest but certainly are amongst the best. The fact that when installed correctly they can deliver an amazing sound makes them excellent value for money.

As to my customer with the Ford, he now has a fabulous system based around a JL Audio amp and speakers with a Rainbow active sub. He loves to play it loud and I know it will give him years of pleasure without doing any harm.

If you want to experience the Discovery sound system or would like to discuss how we can improve your car please all us on 01625 432707.

Audio Installation with Full Instrumentation!

Over the 40 years that Car and Home Stereo has been installing audio systems to cars we have seen enormous changes. Changes to the source units available (who else remembers 8 track cartridges?!), changes to the playback systems and of course changes to the vehicles themselves. While a 1970’s Ford Escort shares a common purpose with a 2016 Audi TT, they share very little under the skin.

Most vehicle systems now are completely controlled by the on-board computers, true Drive by Wire. These systems have meant much greater reliability, higher efficiency and flexibility. However it has also led to a much lower tolerance of interference with respect to changes. Even the slightest change to a vehicle system can generate fault codes and even lead to vehicle malfunction.

dsc_0043

This, coupled with fully integrated entertainment systems would appear to spell the end of audio upgrades, leaving you stuck with the dull factory installed system but help is at hand!

Fortunately our industry has risen to the challenge and developed systems that can be seamlessly integrated with any factory system regardless of complexity.

If you have a Bose or Infinity audio system in your car then the speakers may well be of a lower impedance than standard. This would mean a blown speaker could not be replaced with an alternative to the factory part but we now have speakers that are specifically designed to be added to factory systems meaning perfect fit and far better sound.

landrover-speakers-side-by-side

You may want to change the basic radio in your VW Golf to something with DAB radio or satellite navigation. The standard VW radio also displays parking information and climate control settings, there are controls on the steering wheel for volume and track search. These are features you would not want to lose and we can supply units that have all the facilities you may want as well as supporting all the standard vehicle displays.

With the advent of computer controlled systems there are also hazards to changing the head unit to one that is not compatible with the vehicle wiring. The results can be from your new unit not working to damage to the electrical system. At Car and Home Stereo we take safety very seriously and have a wide range of specialist interfaces to ensure that any new system integrates perfectly with your car.
