Setting input trim levels

Proper setting of the [TRIM] controls is crucial to
Instead of doing this, get as much gain as possible as close to the signal source as possible. If you've plugged a synthesizer or other
The goal is to get the signal as loud as possible as early as possible in the signal path, without causing clipping (distortion) anywhere in the path or in the sound system.
PEAK LED method
Each channel of the Multimix 12R has its own [PEAK] indicator, which will light when the signal level rises to within 6 dB of clipping. In situations where the maximum
✪When the PEAK LED is flashing, it does NOT necessarily mean that distortion has occurred. There is usually some headroom left if the PEAK LED is flashing momentarily on the loudest peaks.
1.With the sound source active, and the channel fader down to minimum, raise the [TRIM] control until the PEAK LED flashes occasionally on the loudest transients.
2.If desired, lower the [TRIM] control slightly until the flashing stops.
Note for extremely high level line inputs in stereo channels: If the [TRIM] setting is set below unity (12 o'clock position) on a stereo channel, it is possible for the first input stage to clip without the PEAK LED coming on. If distortion is still heard after lowering the trim to its minimum setting, it means the source is extremely high (+22 dBu or higher). In this case you must lower the output level of the source, use an external pad, or repatch to a LINE IN on channels
