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 Studio 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.)
