DTP CrossPoint 84 Series Matrix Switchers • Operation 27
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 page100).
If you change the group master configuration, the front panel controls adjust the new
group masters that you create.
I
Mic Volume (gain) knob and LEDs (see figure17 on page22) — Rotate the knob
clockwise to increase the pre-mixer gain for all four microphone inputs. By default, this
knob controls DSP group master 2.
J
Volume knob and LEDs — 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 0 (-100 dB) to 100 (+12 dB). The default
setting is 50 (-50 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. As you increase and
decrease the volume, the top LED that is lit blinks.
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).

IPCP LEDs —The DTP CrossPoint 84 IPCP includes a built-in IPCP control processor
that can control and monitor a variety of external devices. The IPCP control processor
display its operational status on the front panel. See the IPCP Pro 350 Series User
Guide at www.extron.com to interpret the indications of the IPCP control processor.
