QM 1000P User Manual Basic professional audio practice and hints for best results. PRE-AMPLIFIER: A part of the signal chain where a signal from a microphone, turntable, CD player or other source is first amplified. This will normally be at the input of a mixer. The pre-amplifier is necessary to boost the signal enough to be then mixed and amplified by a power amplifier. POWER AMPLIFIER: Boosts the signal enough so it can be reproduced by a loudspeaker.
QM 1000P User Manual Operating Tips To avoid overloading the pre-amp inputs, always operate the master volume at a high level and control the volume from the input volume. The ideal situation is to have all the components of the audio chain operating at the same operational range. MIXER 10 10 5 5 1 1 1 10 CLIP/LIMIT 2 MIXER Do not operate the system with the input peaking (red overload light on or flashing) and the master volume turned down.
