4 Channel AEC Input Expansion Cards For Use With Symetrix Edge and Radius DSP Management Systems

  • Wideband dedicated processing.
  • Zero-latency direct outputs and discrete reference inputs per AEC channel.
  • AEC processing available to the card’s direct inputs or internally routed sources.
  • 11 mS AEC latency, up to 300 mS tail length, and greater than 100 dB/S convergence time.
  • Field swappable by certified technicians.

The device provides four acoustic echo cancellation inputs to an EDGE or RADIUS AEC frame with coarse gain, fine trim and phantom power. Up to four of these devices may be installed in a single EDGE frame for up to sixteen channels of local input and up to one of these devices may be installed in a single RADIUS AEC for up to four channels of local input. Levels, phantom powers, signal inversions and mutes are controllable via software. Audio inputs shall be accessed via rear panel 3.81 mm terminal block connectors.

Audio conversion is 24-bit, 48 kHz. The dynamic range shall not be lower than 115 dB, A-weighted with a maximum input level of +23 dBu.

The device complies with CE and FCC Part 15 emissions limits. The device is RoHS compliant. The mounting plate is constructed of cold rolled steel, and mount into a SymNet Radius AEC or EDGE frame I/O card slot. The device is a Symetrix SymNet 4 Channel AEC Input Card.
