DLC-250.4 LOUDSPEAKER CONTROLLER
11
Configuration
•
The
GPIO Volume Control
option enables external volume control
to be applied to individual zones. The GPIO configuration menu can be
found under the
Settings Tab
.
•
The
Compressor
option enables default or custom signal
compression to be applied to individual installation zones.
Note: Compression can be useful to reduce the volume
difference between loud and quiet audio material. The lower the
compression threshold is set, the more the difference between
loud and soft will be reduced. The overall zone volume may
need to be increased when compression is used. The default
compression parameters are appropriate for most installations.
5.3.3 Output Tab
The
Output Tab
enables amplifier outputs to be named and provides
access to further sub-menus. For all Output Tab menus, the amplifier output
under configuration is selected by highlighting one of the output identifiers
(1, 2, 3 or 4) at the top of the display. The
Output Tab
also enables
Speaker Preset
configurations to be created, exported, imported or
cleared.
Diagram 5d
illustrates the
Output Tab
.
Note: The number of individual outputs available for configuration
will depend on the THEORY DLC amplifier model and the input,
zone and output mode configuration.
•
The
Routing
menu enables zones to be assigned to amplifier outputs.
Note: Routing for zones specified as stereo will automatically
offer three output options: left channel, right channel or summed
mono. The summed mono signal can potentially be used to drive
a mono subwoofer.
