NetMax 8-Channel Analog Output Card
The AO-1 is an eight-channel analog output module for use in an Electro-Voice N8000 system. The module offers eight high quality audio signals via screwlockable Euroblock connectors. A-to-D conversion is taken care of by high performance linear 24-bit converters. Internally the signals are processed in 48-bit word length.
Features:
• 118 dB dynamic range – for best audio performance
• 100 Ohms balanced output drivers - lossless signal distribution to several inputs, even over longer
cables
• Output relays - power-on delay and quick disconnection for effective suppression of poweron/-
off noise. Automatic control of parallel-wired redundant systems
• Automatic configuration – indication (message) of installation and removal of modules via IRIS-Net
software
• EN 54-16: 2008
