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.
