Phasers on Stun! This month’s final frontier is to the highly critical, planet phase. To kick off, we need to make sure you all understand how sound gets to your ears. Sound is basically the detection of movement of air entering our ears and creating sympathetic movement of the ear drum. The more violently the […]
Found in Space
Posted on 15th October 2014
Found in Space Look closely at the above image. Can you see a whole load of stars or just a vague homogenous glow? I hope it is the former as otherwise this entire post fails. Once more, I want to speak about separation in audio systems. This is a concept which many find extremely hard […]
16 bit vs 24 bit-depth audio
Posted on 24th September 2014
16 bit vs 24 bit-depth audio This topic is probably one of the most difficult to boil down for the lay person! Digital audio is a very complex and controversial business due to the apparent need to parameterise what is considered by many to be as psychological a phenomena as it is physics-based! An example […]
Parametric vs Graphic – Equalisation with knobs on!
Posted on 26th August 2014
Already struggling with terminology? For those who are, I will start by telling you that “equalisation” is simply a posh term for tone control. Sometimes these appear as bass and treble on audio equipment but in a car, this is never adequate in order to tailor sound to match the listening environment. Graphic Equalisers Since […]
The Length The Width And The Breadth Of Sound
Posted on 16th July 2014
The Length The Width And The Breadth Of Sound Human ears are wonderful things and when combined with the brain are capable of tremendously precise feats of perception. As hunter gatherers, our ears allowed us to hear our dinner moving about in the primeval forests we hunted and not only hear it, but analyse how […]
Strangled Power Kills Car Amplifiers!
Posted on 11th June 2014
Strangled Power Kills Car Amplifiers! – How? – Read on. In a previous blog (http://blog.fourmasterscaraudio.co.uk/what-watt-is-what-for-car-audio/), we looked at the importance of power rating. We don’t have enough room here for a ground-up review but suffice to say, we were specifically focussing on matching like for like power ratings. We have also blogged about distortion and […]
Car Speaker Cones
Posted on 25th March 2014
Car Speaker Cones Since the first moving coil speaker was developed in 1924, researchers have spent astounding amounts of time looking to improve its performance. The first principles of speaker design haven’t really changed that much since then; create a motor using a coil of wire sitting in a magnetic field, send electrical impulses through […]
Car Audio Class System – Size Matters
Posted on 17th February 2014
Car Audio Class System – Size Matters When studying the technical features of a car amplifier, you will come across a strange parameter called “class”. A full explanation requires a good knowledge of how transistors work but here we try to give you a guide that may help you when comparing different products. Class A, class […]
Making all the Right Signals
Posted on 21st January 2014
As vehicle manufacturers continue to bury their car stereos deeply into the dashboard and beyond, the professional audio installer has had to find ways of taking the speaker outputs from these and making them suitable to feed into the line-level signal input of an amplifier. For those who have absolutely no idea what I am talking […]
Power Distribution in Car Audio Systems – Gotta Get Yourself Connected
Posted on 20th November 2013
Power Distribution in Car Audio Systems – Gotta Get Yourself Connected I = TP X 2/Vbatt In a previous blog we wrote about power measurements in a car audio system in an attempt to demystify this often misused and misquoted parameter. In so doing, we touched extremely briefly on the concept of power consumption as […]
