Rear Panel

Analog Audio Outputs
The DAC2 DX has three stereo analog outputs driven from two separate output busses. By default
both busses are controlled from the front panel volume control. Either or both busses may be
programmed to BYPASS the volume control. When an output bus is set to BYPASS, the output
level is set to a calibrated maximum level. The XLR outputs can deliver +24 dBu. The RCA outputs
can deliver 2 Vrms (8.2 dBu).
The MAIN output bus drives a pair of balanced XLR outputs and a pair of unbalanced RCA outputs.
The AUX output bus drives a pair of unbalanced RCA outputs.
Digital Audio Inputs
The DAC2 DX has six stereo digital inputs (1 USB, 1 AES XLR, 2 optical and 2 coaxial). The XLR,
coaxial and optical inputs accept professional (AES) and consumer (S/PDIF) data formats at word
lengths up to 24-bits. The optical inputs are limited to 96 kHz sample rates. All other inputs
support sample rates up to 192 kHz.
12V Trigger I/O
The 1/8" TRS jack on the rear panel is a bi-directional 12V trigger connection to enable power
sequencing between the DAC2 DX and other audio devices in the signal chain. If the tip of the TRS
connector is driven to 12 volts, the DAC2 DX will turn on. If the DAC2 DX is turned on locally, the
DAC2 DX will drive the tip of the TRS connector to 12 V to turn on other linked devices.
AC Power Input
The DAC2 DX is equipped with a universal power supply. There is no voltage selection switch. AC
voltage range is 88-264 VAC, 50-60 HZ. The fuse drawer contains two fuses, always use exact
replacements.
