The general rule about using EQ is to be very careful about too much 'lift'. 
Increasing the gain by say 10dB in the high frequencies has the effect of 
taking the MQ3 closer to overload. This is generally OK as the MQ3 is 
designed with very generous overload margins, but when using EQ this has 
to be remembered. The rule is that when 'lift' is used, it's often necessary to 
compensate by reducing the input gain.

Note, always alter sound from the ground up; i.e. with the EQ controls set to 
the 'flat' or 0 position.

A red LED indicator shows overload conditions at the output of the equalizer 
section of the MQ3. When this indicator flashes, it shows that the audio 
signal is within 6dB of the overload point. This a very useful indicator as it 
allows you to operate the EQ knowing that there will not be distortion in the 
output.

If the overload light flashes more than 'occasionally', then decrease the 
input gain control. - See block diagram for detail on overload indicators.

MQ3 CONTROL EXPLANATIONS.

'INPUT GAIN' changes the audio amplification of the input amplifiers of the 
MQ3.  Too little gain and the sound will be too quiet and electronic 
background noise from various sources could become a problem; too much 
and the MQ3 could become overloaded and distorted.

‘MIC’ when pressed in enables the microphone input on the rear panel.
When out, the unit will respond to the line input

‘COMPRESSION' simply adds gain to the compression sidechain and so 
increases compression. In simple terms this changes the 'threshold' of the 
compression although with this compressor the 'threshold' is not clearly 
defined; the compression starts very gradually and the compression ratio 
changes with programme content and volume.  For practical purposes, 
winding up the compression control increases the amount of compression. 
In use you will find that musically, all controls are interrelated.

'ATTACK' sets the time that the compressor takes to act. At maximum 
(slowest) it's possible to make the compressor 'overshoot' on some 
percussive programme material: This means that the compression
