The 8910ADA-ST offers cost-effective
distribution of monaural or stereo analog audio
throughout your facility. In stereo mode there
are four pairs of outputs, and in monaural
mode there are eight outputs. Featuring flat
frequency response to maintain your signal
integrity, the 8910ADA-ST offers a wide range
of gain controls using a combination of board
jumpers and local gain adjustment from the
front of the module. Channel 1 and 2 gains
are controlled separately so you can use this
board as a dual 1x4 analog audio distribution
amplifier. Additionally, you can easily monitor
the condition of the module with our popular
Ethernet interface, which provides a convenient
Web interface, Newton control system, and
SNMP monitoring.
