Audio Settings
The Audio Settings page allows you to route audio and adjust DSP settings.
There are a total of 28 input slots and 12 output slots. Any combination of input types
(i.e., analog, VoIP, USB, etc.) can be configured, and same-type input channels can be
stereo ganged if required for the application.
Any combination of output types can also be configured (i.e., analog, VoIP, USB, etc.).
Same-type outputs can be stereo ganged, or each output can be duplicated (mirrored)
to up to 7 additional outputs for applications requiring multed outputs.
Filter
Press this button to select the type of channels that are visible on the page. Use the
Hide unused channels checkbox to hide channels that are not configured.

channel. Input channels 13-28 have a Compressor available.
AutoMixers
There are a total of 4 AutoMixers located in the center of the Audio Settings page. To
route channels through an AutoMixer, select the AutoMixer then check the boxes for the
input and output channels that you wish to assign. The colored strips on each
input/output channel strip correspond with the colored border of each AutoMixer to
provide at-a-glance identification of AutoMixer routing assignments. Double-click an
AutoMixer to access its settings.

Signal Generator
Select the white area of the Signal Generator channel to view the Signal Generator
settings.
AEC Reference Groups
The AEC Reference Groups are used to inform the AEC algorithm which signals will be
referenced for processing, which includes the conference room mics (the outgoing
signal) and the incoming call signal (the signal to be cancelled so that it isn't transmitted
as an echo). There are a total of 4 AEC Reference Groups, one for each conference
room.
Before assigning any AEC Reference Groups, you must first configure the input
channels and then enable AEC for all inputs that will use AEC.
To assign an AEC Reference Group, select the group and then check the checkbox in
the AEC icon for all input channels that you wish to assign to the group. You must then
check the checkbox to the right of the input that carries the incoming call signal.

Input Channel Configuration
Input Channel Name
Click the Pencil icon to rename the input channel.
EQ, AEC, and Compressor Tabs
Use these tabs to navigate to the input channel's PEQ, AEC, or Compressor page. Input
channels 1-12 have AEC processing while input channels 13-28 have a Compressor
instead.
Input Type
Select the desired input type using these radio buttons. Options include Analog, VoIP,
USB, AES67, BLU Link, and Not Used.
Note: To configure a channel, you must select an Input Type and then an Input
channel number before closing the window.
Matrix Input Gain, Meter, and Mute
This meter displays signal level (in dBu) post input processing. The dot to the left of the
meter lights green to indicate signal presence or red to indicate clipping. Use the Matrix

Input Gain field or slider to adjust the signal level feeding the output(s). Use the Mute
button to mute the input channel.
Stereo Input Switch
Use this switch to stereo gang input channels. To stereo gang two channels, you must
first configure both with matching Input Type selections (e.g., analog, VoIP, USB, etc.).
The Stereo Input switch will then be visible on the lower-numbered input channel and
can be engaged if required for the application.
Note: Only non-AEC input channels (13-28) can be stereo ganged.
