SX-2100AO

Fully digital audio output unit for installation in 19-inch cabinet racks (IEC 60297) with 8 balanced audio outputs for connecting the amplifier of the VP-2000 series.
Two network connections (100BaseTX) for redundant network for audio and control signals, zusätz¬Licher analog reserve way. Redundant power supply for reliable power supply. 8 Control inputs with opto-couplers and 8 control outputs with relay contact, normally closed or normally open free choice, with removable terminal blocks. Two inputs for local audio sources to transfer in one or more programmable areas.
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
-Modulation bar indicator for two local inputs
-Status of each channel (on/off)
-Communication error of the network channels
-Collective fault signal
-Communication error (data line)
-Emergency mode
Buttons to select of the display of the system information. Four function keys to choose of pre-programmed music transfers or activating a transfers of a receipt 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. 6 Can be freely selectable filter per channel (parametric equalizer, high and low-pass, all pass, CD-Horn equalizer, treble / bass control, notch filters), delay (delay) to 682 ms and compressor. Monitoring of all alarm-relevant signaling pathways including the connected amplifier and loudspeaker lines, CPU, power supply and network connections. Speaker line monitoring for short-circuit, break and Earth faults with intelligent, digital impedance control or with Linienendmodulen for each channel separately selectable. Adjustable tolerances for impedance deviation: short circuit: - 50% - 95%, interruption: + 1% to + 700%. Monitoring connection for two emergency power supply units. Control of the Energiespar¬modus of the amplifier to minimize the current drain of the battery during a power failure. Automatic switching to shipwreck amplifier an amplifier failure.
