DigiMatch 2×6 is an AES/EBU-to-SPDIF interface and distribution amplifier for digital audio signals. DigiMatch has two distinct functions: (a) to convert between professional (balanced) AES/EBU and consumer (unbalanced) SPDIF digital audio signals; and (b) to distribute a digital input signal(s) to multiple destinations.
DigiMatch has 2 inputs and 6 outputs: an AES/EBU input and 3 AES/EBU outputs, plus an SPDIF input and 3 SPDIF outputs. Either input can feed either or both sets of outputs, producing 4 possible modes of operation:
Convert: AES/EBU input feeds SPDIF outs; SPDIF input feeds AES/EBU outs
DA-AES/EBU only: AES/EBU input feeds ALL outputs
DA-SPDIF only: SPDIF input feeds ALL outputs
DA-Split: AES/EBU input feeds AES/EBU outputs; SPDIF input feeds SPDIF outputs.
Modes are selected using front panel switches. The “Convert” mode is essentially a “digital MatchBox,” providing bi-directional conversion between AES/EBU and SPDIF digital circuits, without altering any data in the bitstream.
DigiMatch circuitry automatically corrects input levels that are out of tolerance. All 6 DigiMatch outputs can be used simultaneously and without interaction. The AES/EBU inputs and outputs are transformer isolated. All outputs are short-circuit protected and can drive long lines without signal degradation.
DigiMatch is 1/3 rack width and can be mounted in an optional rack shelf, or wall-mounted using optional wall/cabinet mounting brackets. DigiMatch is powered by an internal AC power supply.
