Frequently asked questions

The DAC3 DX supports 24-bit D/A conversion of PCM at sample rates up to 192 kHz, and direct conversion of 1-bit DSD at a 2.8224 MHz sample rate. It also supports DoP 1.1 format for DSD signals streamed over USB or Coaxial inputs.

The DAC3 DX has two USB modes: USB Audio 1.1 (up to 24 bits at 96 kHz) and USB Audio 2.0 (up to 24 bits at 192 kHz plus DSD in DoP 1.1 format).

The CALIBRATED mode sets the MAIN and/or AUX output buses to factory calibrated levels. It is useful when the system volume is controlled before or after the DAC3 DX, as it avoids the potential issues of having two cascaded volume controls.

The 12V TRIGGER I/O port can be used as an input, an output, or both. It can be connected to other audio components to turn an entire audio system on and off in a controlled sequence.

The headphone jacks on the DAC3 DX include switches that can be programmed to mute the MAIN outputs. When enabled, the MAIN analog outputs (XLR and RCA) are muted when a headphone plug is inserted.
