Using the meter
The meter of the Multimix 12R is a fast peak type that reads in decibels, normally displaying the level of the [MAIN OUT] jacks. When the meter reads "0", the main outputs are at the nominal level: the phono jacks at
Use this reference level to calibrate your system. The input controls of analog recorders should be set so that “0” on the mixer's meters equals “0 VU” on the recorder's meters. Digital recorders use a different reference; for example, an ADAT connected to the Multimix 12R's outputs will read
The meter follows the [MSTR/TAPE] switch, but not the PHONES/MONITOR level control. Whatever you hear in the headphone output, the master output (up position) or the
Output distortion
The Multimix 12R has plenty of headroom, but eventually every electronic device reaches its limit. At +18 dB over nominal level, the top LED of the meter labeled PK will light; at this point there is 6 dB of headroom before the master electronics will clip. Final clipping is reached at 24 dB over nominal "0" on the meter; this represents a level of +28 dBu at the MAIN OUT jacks if balanced, +22 dBu if unbalanced, and +14 dBV at the MAIN OUT
✪As long as the meter of the Multimix 12R is below its top LED, and the PEAK LEDs of all channels are off, the mixer should not be causing distortion. If you hear distortion, check other devices in the signal chain for overload, and make sure the STEREO channels' PEAK LEDs do not come on when their TRIM is set to 12 o'clock.
