Epica DGX 32 Instruction Manual
Adjusting Audio
Note: This section of the manual does not apply to embedded audio transmitted over SC fiber cables.
Some audio boards in AMX AutoPatch Distribution Matrices offer optional volume control and digital
input gain adjustment features. If your Epica DGX 32 system is linked to an enclosure that contains these
boards, output volume or digital input gain can be adjusted using either the Epica DGX 32 control panel
or BCS commands sent through a serial controller. For more information on audio adjustment using BCS
commands, see the
BCS Protocol Instruction Manual
.
The Adjust Volume Screen displays the current volume setting and the range available for the specific
audio output board that has been selected for adjustment. The Adjust Input Gain Screen displays the
current gain setting and the range available for the specific audio input board that has been selected for
adjustment.
When volume or digital input gain is adjusted for a device on one virtual matrix, the adjustment remains
in effect for that device on all virtual matrix switching audio signals.
Important: For AMX AutoPatch systems, the total through-system gain (the amount of input gain plus
the amount of output gain) specified for any input/output routing path cannot exceed 10 dBr. If you
enter a volume (gain) command that exceeds 10 dBr when it is combined with the gain of an input, the
command will be accepted (and will be indicated in status results) but will not result in an audible
difference of more than 10 dBr.
When the panel is placed in any of the Audio Modes, available keys will be blue and any unavailable ones
will not be illuminated. When you select a blue key, it turns white indicating that it is ready for the audio
adjustment.
You can adjust output volume, mute outputs, and adjust input gain from the Epica DGX 32 control panel
using the steps on the following pages.
You can return to the Function menu at any time by pressing the Function Key.
Adjusting Output Volume
If an Epica DGX 32 is linked to an enclosure that supports volume control, adjustments (within the
volume range for the specific audio output board) can be made at any time during time normal operation.
When audio is adjusted for a device on one virtual matrix, the adjustment remains in effect for that device
on all virtual matrices switching audio signals.
To adjust the volume:
1.
Press the Function Key.
The Function menu appears.
2.
Locate Adjust Audio by scrolling with the Control Dial.
