DAC2 DX Instruction Manual Rev A Page 21

The Coax inputs are DC isolated, current limited, and diode protected. The RCA body is bonded

directly to the chassis to prevent currents in the internal ground system. This direct bonding also

maximizes RF shielding.

TIP: Shielded 75-Ohm coaxial cable is required for stable performance. Do not use 50-

Ohm cables or twisted pair cables, or any non-coaxial cables.

The Coaxial inputs accept AES/EBU or S/PDIF digital audio formats. AES3-id and SMPTE 276M

standards specify 75-Ohm 1 Vpp professional format digital audio signals and these are commonly

used in video production facilities. IEC 609588-3 specifies 75-Ohm 0.5 Vpp consumer-format

digital audio signals (commonly known as S/PDIF). The coaxial inputs on the DAC2 are designed

to accept either type of signal.

D5 - Coaxial Digital Output

Coaxial connector D5 is a bi-directional port. D5 is factory configured as a digital input. Internal

jumpers can be moved to configure D5 as a digital output.

When configured as an output, D5 acts as a digital pass-through. Any selected digital input will be

routed to D5 without any processing.

PASS-THROUGH MODE can be use for:

 USB to Coax conversion

 Toslink to Coax conversion

 AES XLR to Coax conversion

 Coax to Coax buffering

 Digital routing

 Pass-through to slave DAC2 converters

AES XLR to Coaxial Adapters

Transformers are available to match adapt balanced 110-Ohm AES connections to unbalanced 75-

Ohm coaxial connections. Our experience is that these work well. Coaxial to XLR adapters should

be located near the XLR connector when possible.
