The 8910ADA-SR offers full-featured
distribution of monaural or stereo analog audio
signals. In stereo mode, there are four stereo
outputs, and in monaural mode there are eight
outputs. With this module, audio signals can
be summed for monaural monitoring, swapped
L to R, or phase inverted to fix upstream
transmission problems. Featuring flat frequency
response to maintain signal integrity, the
8910ADA-SR offers a wide range of gain and
balance control options, including local module
control (using paddle controls and a hard-wired
potentiometer for fine adjustment of ±6 dB),
Ethernet-connected Newton™control panels,
and Web browser interface. The user-enabled
audio presence detection feature generates
SNMP traps that can be sent to our NetCentral
SNMP manager, or other SNMP systems for
mission-critical applications.
