Audio Input Unit
The SX-2100AI is an audio input unit of the SX-2000 matrix system and can be mounted in an EIA equipment rack (2U size). Up to 8 units can be installed centralised or decentralised 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 units, but an analog audio bypass (1 channel) enables simultaneous all-zone calls for use in emergency situations in case of a CPU failure. 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 by 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.

482 x 88.4 x 349 mm (W x H x D)
Fully digital audio input unit for installation in 19-inch cabinet racks (IEC 60297) for up to 8 audio sources.
Two network connections (100BaseTX) for redundant network for audio and control signals, additional analog reserve way. Redundant power supply for reliable power supply.
16 Control inputs and 16 control outputs with relay contact, normally closed or normally open freely selectable via detachable connectors.
Four slots for dual-channel modules for a goose, suitable for various signal sources from MIC to line level with various inputs removable screw terminal blocks, XLR and RCA jacks.
Large multicolored display on the front of the machine for:
-18-digit text display for system information
-Modulation bar indicator for each of the 8 channels
-Status of each channel (on/off)
-Status of network channels
-Collective fault signal
-Communication error (data line)
Buttons to select of the display of the system information. Separate display for power supply, standby (standby) and activated analog reserve way.
Four function keys to choose of pre-programmed music transfers or activation of transmissions from an entrance on pre-programmed areas. 8 Channel keys to the switching on and off individual channels, optionally umprogrammierbar on activation of transmissions from an entrance on pre-programmed areas. Volume control for each channel, which is bridged for emergency-related transfers. Access to all the controls can be locked.
Built-in monitor speakers with volume control to listen to each channel.
Compliant monitoring of all alarm-relevant signaling pathways, CPU, power supply and network connections.
