The 8910ADA-M offers cost-effective
distribution of monaural analog audio
throughout your facility. It features a flat
frequency response to maintain signal
integrity. You can easily monitor the condition
of the 8910ADA-M with our popular Ethernet
interface, which provides a convenient Web
interface and SNMP monitoring capability. We
offer a wide range of gain controls using a
combination of board jumpers and local gain
control from the front of the module.
