TOA SX-2000AI เครื่องขยายเสียง Audio Input Unit

Description
The SX-2000AI is an audio intput of the matrix system. Multiple units can be decentralized in a whole system. It is equipped with eight audio outputs and two inputs which can be mixed and output. It is also equipped with eight control inputs, and eight control outputs. The SX-2000AO receives audio signals from the audio input unit via digital transmission, but an analog audio input function (1 channel) enables simultaneous all-zone calls for use in emergency situations. Audio output levels (post-fader levels) are indicated on the level meters provided for each output channel. Any output channel can be monitored using the internal speaker. It is equipped with an emergency audio input and a 24V emergency cutoff input. The SX-2000AO has two power inputs and can support a dual-redundant power supply system.
