SX-2100AI Audio Input Unit
The SX-2100AI is an audio input of the matrix system and can be mounted in an EIA equipment rack (2U size). Multiple units can be decentralized in a whole system. It features modular construction that allows it to handle from two to eight inputs per unit. Audio signals are transmitted digitally to the audio output unit, but an analog audio output function (1 channel) enables simultaneous all-zone calls for use in emergency situations. Audio input levels are indicated on the level meters provided for each input channel. Volumes can be adjusted for each channel using the volume controls on the front panel or the SX-2000 software. The volume controls can be locked. Any input channel can be monitored using the internal speaker. It is also equipped with 16 control inputs, and 16 control outputs. It is equipped with two power inputs, allowing for a redundant power system.
