Operating Instructions Typical Fader and Control Levels Ideally, after you have set the [TRIM] controls, both the Channel and Master faders should be run between the -10 dB and 0 dB position (about 1/2 to 3/4 of the way up the fader travel on the channels, and 3/4 to full on the master) if possible. This position gives the greatest amount of headroom and low noise. It also allows for any additional increase or decrease in level that might be required during mixing. Ultimately, the fader levels are dependent on the requirements of the mix; these suggestions are only a starting point. Unity gain points Unlike many other mixers, the Multimix 12R's [MASTER] fader is designed for unity gain (0) when the fader is up full, not at 3/4 or 1/2 of the travel. This allows you greater control to use the fader for smooth, gradual fade-outs. It also discourages inexperienced operators from using the mixer incorrectly. The channel faders' unity gain point is at the traditional 3/4 point, with 10 dB of gain at the full-up position. Trim gain ranges The amount of gain in the TRIM circuit is shown on the front panel. On channels 1-8, the LINE input ranges from 10 dB attenuation to 40 dB gain, a range that should cover almost any line signal. The MIC input ranges from +10 dB to +60 dB gain, since the very low output voltages of microphones need to be amplified a great deal. The stereo channels' TRIM controls can be set from -15 dB attenuation to +15 dB gain. See the Level Diagram near the end of this manual for a graphic display of the gain structure of the mixer. Aux Send levels The nominal or unity gain points of the Aux 1 and Aux 2 controls are at the "2 o'clock" position. At the full clockwise setting, they have 10 dB of gain. However, in most applications you won't need that gain, if the TRIM controls have been set properly. (See "How to Set Aux Send and Return Levels" later in this chapter for more information.)

Operating Instructions
Typical Fader and Control Levels
Ideally, after you have set the [TRIM] controls, both the Channel and
Master faders should be run between the -10 dB and
0 dB position
(about 1/2 to 3/4 of the way up the fader travel on the channels, and
3/4 to full on the master) if possible.
This position gives the greatest
amount of headroom and low noise.
It also allows for any additional
increase or decrease in level that might be required during mixing.
Ultimately, the fader levels are dependent on the requirements of the
mix; these suggestions are only a starting point.
Unity gain points
Unlike many other mixers, the Multimix 12R's [MASTER] fader is
designed for unity gain (0) when the fader is up full, not at 3/4 or 1/2
of the travel.
This allows you greater control to use the fader for
smooth, gradual fade-outs.
It also discourages inexperienced
operators from using the mixer incorrectly.
The channel faders' unity gain point is at the traditional 3/4 point, with
10 dB of gain at the full-up position.
Trim gain ranges
The amount of gain in the TRIM circuit is shown on the front panel.
On channels 1-8, the LINE input ranges from 10 dB attenuation to 40
dB
gain, a range that should cover almost any line signal.
The MIC
input ranges from +10 dB to +60 dB gain, since the very low output
voltages of microphones need to be amplified a great deal.
The stereo
channels' TRIM
controls can be set from -15 dB attenuation to +15 dB
gain.
See the Level Diagram near the end of this manual for a graphic
display of the gain structure of the mixer.
Aux Send levels
The nominal or unity gain points of the Aux 1 and Aux 2 controls are
at the “2 o’clock” position.
At the full clockwise setting, they have 10
dB of gain.
However, in most applications you won’t need that gain, if
the TRIM controls have been set properly.
(See “How to Set Aux Send
and Return Levels” later in this chapter for more information.)
