In spite of what advertisements may say, it is not possible to replicate the 
complex musical effects of the JOEMEEK compressor either with a VCA 
compressor or with any digital system. 

3) THE EQUALISER

WHAT IS AN EQUALISER?
It's basically a tone control. But on your home HiFi the tone controls give a 
limited amount of adjustment to the sound. The British Channel gives 
enormous range of control allowing you to sharpen or soften the sound with 
the HF (high frequency) control, add 'bite' or push a sound back into a mix 
with the variable frequency mid controls, and add or subtract 'weight' with 
the LF (low frequency) control. An IN/OUT switch lets you try out settings 
and compare them to the 'flat' condition.  There are very many sophisticated 
equalisers on the market; most will change a sound well but very few will 
add character to a sound like the JOEMEEK equaliser. 

THE THREE PARTS IN COMBINATION

The 'order' of the parts of the British Channel is logical; first the input 
stages, either microphone, line or instrument input. This is followed by the 
'INSERT' where the audio can 'loop' through other outboard equipment to 
add effects for example.

This is followed by the JOEMEEK compressor and then the Equaliser.
The output stage buffers the output of the equaliser so that the BRITISH 
CHANNEL can drive into any sort of mixer or power amplifier.

CONTROL EXPLANATIONS

'PAD 20dB' puts a 20dB 'pad' (reduces the gain by 20db) into the 
microphone input. An LED shows that this pad is in circuit.

'PHANTOM' connects stabilised 48V power to the microphone input to 
power capacitor microphones. LED indicates that 48V power is on.

'LINE INPUT' switches the XLR  microphone input off and the LINE socket 
on. LED indicator shows when 'LINE' is selected.

'PHASE' inverts the phase of the whole channel. Yellow LED indicates that 
the phase is inverted.

'INPUT GAIN' changes the audio amplification of the input amplifiers of the 

VC6Q
