Architect and Engineer Specifications: SymNet 4 Channel Analog Input Card.
The device shall provide four analog mic/line inputs to an EDGE or RADIUS AEC frame that are adjustable from line to mic level 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 frame for up to four channels of local input. Levels, phantom powers, signal inversions and mutes shall be controllable via software. Audio inputs shall be accessed via rear panel 3.81 mm terminal block connectors.
Audio conversion shall be 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 shall comply with CE and FCC Part 15 emissions limits. The device shall be RoHS compliant. The mounting plate shall be constructed of cold rolled steel, and mount into a SymNet Radius AEC or EDGE frame I/O card slot. The device shall be a Symetrix SymNet 4 Channel Analog Input Card.
