4 Channel Digital Input Card
- 4 channels (2 stereo pairs).
- Pro or consumer – AES/EBU or S/PDIF.
- Connect to any source – sample rate converts 12 to 192 kHz input signal to 48k internal clock.
- Level matching – +/-24dB digital trim.
- Field swappable by qualified technicians.

Architect and Engineer Specifications: SymNet 4 Channel Digital Input Card.
The device shall provide two pairs of digital inputs (4 channels total) to an EDGE or RADIUS AEC frame that are adjustable with fine trim and selectable in format between AES or S/PDIF.
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, mutes, inversions and formats 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 with ability to accept 12 to 192 kHz using a sample rate conversion. The dynamic range shall not be lower than 128 dB, unweighted with a maximum input level of 0 dBFS (+24 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 Digital Input Card.
