Multi-Channel & Mono-Channel Differences

If your car audio sound system is not meeting your expectations then maybe your specifications are to blame.  When examining mono and multi-channel amplifiers, there a few specifications that you should pay closer attention to than others.

Multi-Channel Amplifiers

2, 3, 4, 5 or more channel amplifiers are usually Class A/B.  The class is determined by the configuration of the circuitry.  Class A/B circuitry leans towards being more inefficient but provides higher sound quality.  This makes them ideal for mid to high frequencies but are sometimes used for subwoofers as well.  They will also run at much cooler temperatures considering the lower wattage applications they are required to be operated in.  If you are considering purchasing a multi-channel amplifier, then the following specifications should be kept in mind to sway your decision:


  • Signal-to-Noise Ratio: This figure refers to the strength of the signal vs. the level of back ground noise.  A high value will indicate a lower background noise and as a result, a better signal.
  • THD (Total Harmonic Distortion): This is the measurement of the harmonic distortion that is present.  It can be explained as the change in the signal as it is being amplified and exactly how much it is changed.  A lower value is desirable and a THD value of less than .10% is inaudible.
  • Channel Separation:  Sometimes referred to as “cross talk” this value indicates the level of interference between channels.  This value is measured in decibels and the higher the value, the greater and more effective the channel separation will be.

Mono-Channel Amplifiers

Mono-Channel Amplifiers usually are Class D.  These amplifiers are going to be able to obtain lower ohm loads and higher output which makes them ideal for subwoofers. They are more efficient then their class A/B counterparts. In recent years, monoblock amplifiers have become more efficient and with smaller chassis. Features such as signal-to-noise ratio and THD will often be negatively effected. However, these specifications are not as important as others in regards to mono-channel amps. When examining mono amplifiers there a few different specs you should pay a bit more attention to:


  • Damping Factor: Having a high damping factor means there is a high ratio between the nominal load impedance (typically 8W ) and the source impedance of the amplifier.  It is said that the higher this value is, the more cone control is present which results in a better system response and more accurate bass.
  •  Pre-Amp Outputs: Most Mono amps have pre-amp outputs to daisy chain multiple amplifiers together without splitting the pre-outs from your head-unit.
  • Subsonic Filter:Only on mono amplifiers, this filter allows you to block frequencies that are not able to be reproduced by your subwoofer.  This filter is usally variable between 15-50 Hz.

Using an amplifier in the wrong application is bad, mkay.

Professional Home Headphones

The want for high-quality sound reproduction is what sets the true audio listener apart from your average every day listener. Headphones like the SR60i and SR80i from Grado offer a fuller sound reproduction that is almost never seen in your standard pair of headphones. Here you will get cleaner, crisper and more accurate highs, mids, and lows. Kicker’s HP541 headphones also provide that higher-quality that makes listening to music a whole new experience.

Professional DJ Headphones

With professional DJ style headphones not only is sound quality important but aside from that they must feature some sort of swivel of the ear-cups and extreme flexibility. Pioneer’s HDJ-500K, and HDJ-1000 offer unique folding housing and joint movement that allow for flexibility during performance which allow for easier use when mixing. The same goes for the Shure SRH750DJ and SRH550DJ headphones. These headphones excel in low and mid frequency reproduction which is essential to a good DJ. A DJ is only as good as his equipment, and these DJ style headphones will allow for true artistic presentation.

Professional Studio Headphones

Studio monitoring headphones are a complete different ballgame in the professional headphone category. These headphones will pick up a very wide range of frequencies which is needed for proper monitoring and mixing. Audio Technica’s ATH-M50, Sony’s MDR-V600, and Sennheiser HD 280 Pro headphones all offer a very dynamic sound reproduction and are able to reproduce frequencies that are not always heard but play a significant role in the overall sound quality and production. Studio monitoring and mixing professional have a great sense of hearing but even they need a reliable pair of professional studio headphones to get the job done as accurate as possible.


The Pioneer CDJ2000 Vs. The Pioneer CDJ900

Visually these two units are virtually the same as they have the same footprint, transport controls, and layout of the features and buttons.  The first difference that you may notice in a side to side comparison is the beautiful organic LED illuminated screen of the CDJ2000 with adjustable brightness and animation  as well as the illuminated rings around the play pause buttons just the lights off of this media player is a show in itself.  The CDJ900 LCD screen is no slouch by any means as it displays more information that any previous CDJ model.

There is a slight difference in the illumination of the jog wheels.  The CDJ900’s Jog wheels have a really nice feel but the CDJ2000 has a tension adjustment for supper slick touch and feel or you can really put the brakes on for some precision scratching.

The CDJ2000 features a hot loops section where your selected loops can be stored and recalled at the push of a button. Loop and cue points can even be saved to an SD card.  This is opposed to the CDJ900’s auto beat loop section which will cue up any of 8 looping modes using the four auto loop keys in conjunction with shift key.

Something that the CDJ900 features that the CDJ2000 does not is the slip feature.   This powerful little button allows you to manipulate the jog wheel to cue and scratch but will return to the beat and song point as if you had not engaged the jog wheel instantly as you let go.  A particularly wonderful feature for DJs who play more mature themed songs at youth oriented functions such as school dances.

The CDJ2000 features and adjustable break speed as well as release speed so you can manipulate start and stop impulse times. The CDJ900 only has fixed corresponding vinyl speed adjustment, meaning that if you stop slow, you start slow and vice versa.

The features of the CDJ2000 may overshadow the lower priced CDJ900 although that’s not to say that the CDJ900 is not an incredible machine.  If the CDJ2000 is a fighter jet then the CDJ900 is the world’s greatest stunt plane.
