User manual GRASS VALLEY 8910ADA-SR DATASHEET

[. . . ] 4 8910ADA-SR Stereo Analog Audio DA w/Remote Control Key Features · Stereo and monaural modes · Audio presence detection with SNMP reporting · Frequency response of 20 Hz to 20 kHz ±0. 05 dB · Gain/balance level controls · Gain range from ­20 dB to +30 dB set with remote controls or front edge paddle switch · Sum, swap, or invert signals · Max. [. . . ] 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 NewtonTM 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.
