CARE OF YOUR MIXER
General Precautions Avoid 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.
Keep the mixer clean using a soft dry brush, and an occa- sional wipe with a damp cloth or ethyl alcohol. Do not use any other solvents which may cause damage to paint or plas- tic parts.
Avoid 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

|
balance | the relative levels of the left and right channels of a stereo | |
| 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. | |
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) | the practice of connecting an electric musical instrument directly t | |
| the input of the mixing console, rather than to an amplifier | |
| and loudspeaker which is covered by a microphone feeding | |
| the console. | |
equaliser | a device that allows the boosting or cutting of selected bands | |
| of frequencies in the signal path. | |
feedback | the ‘howling’ sound caused by bringing a microphone too close | |
| to a loudspeaker 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. | |
