CARE OF YOUR MIXER

General Precautions

lAvoid storing or using the mixer in conditions of excessive heat or cold, or in positions where it is likely to be subject to vibration, dust or moisture.

lKeep the mixer clean using a soft dry brush, and an occasional wipe with a damp cloth or ethyl alcohol. Do not use any other solvents which may cause damage to paint or plastic parts.

lAvoid placing drinks or smoking materials on or near the mixer. Sticky drinks and cigarette ash are frequent causes of damage to faders and switches.

Regular care and inspection will be rewarded by a long life and maximum reliability.

Glossary

AFL (After Fade Listen)

a function that allows the operator to monitor the post-fade signal in a

 

channel independently of the main mix.

auxiliary send

an output from the console comprising a mix of signals from channels and

 

groups derived independently of the main stereo/group mixes. Typically

 

the feeds to the mix are implemented on rotary level controls.

balance

the relative levels of the left and right channels of a stereo signal.

balanced

a method of audio connection which ‘balances’ the signal between two

 

wires and a screen which carries no signal. Any interference is picked up

 

equally by the two wires, but out of phase resulting in cancellation of the

 

interference signal.

clipping

the onset of severe distortion in the signal path, usually caused by the peak

 

signal voltage being limited by the circuit’s power supply voltage.

DAT

Digital Audio Tape, a cassette-based digital recording format.

dB (decibel)

a ratio of two voltages or signal levels, expressed by the equation

 

dB=20Log10 (V1/V2). Adding the suffix ‘u’ denotes the ratio is relative to

 

0.775V RMS.

DI(direct injection)/DI Box

 

the practice of connecting an electric musical instrument directly to the

 

input of the mixing console, rather than to an amplifier and loudspeaker

 

which is covered by a microphone feeding the console.

direct output

a post fade line level output from the input channel, bypassing the summing

 

amplifiers, typically for sending to individual tape tracks during recording.

equaliser

a device that allows the boosting or cutting of selected bands of frequen-

 

cies in the signal path.

fader

a linear control providing level adjustment

feedback

the `howling’ sound caused by bringing a microphone too close to a loud-

 

speaker driven from its amplified signal.

foldback

a feed sent back to the artistes via loudspeakers or headphones to enable

 

them to monitor the sounds they are producing.

frequency response

the variation in gain of a device with frequency.

gain/input sensitivity

the variation in level of the signal
