Volume Controls
NOTE: The following volume functions are in the default group masters configuration.
Operation of these controls can be changed using the DSP Configurator software (see
Group masters on page 106).
If you change the group master configuration, the front panel controls adjust the new
group masters that you create.
J
Mic Volume (gain) knob and LEDs (see figure 18) — Rotate the knob clockwise to
increase the pre-mixer gain for all four microphone inputs. By default, this knob controls
DSP group master 2.
K
Volume knob and LEDs (see figure 18) — Rotate the knob clockwise to increase the
output 1 amplified volume. By default, this knob controls DSP group master 1.
For both volume controls, the range is from -100 dB to +12 dB. The default setting
is 0 dB. As the volume increases or decreases, the LED bar ramps up and down to
indicate the current volume range, as shown in table 1 on the next page.
The sensitivity of the encoder (the amount [dB] of volume adjustment per step of
rotation) varies depending on the current volume setting (see the last column in table 1).
