EC Designs PowerDAC-BX

Basic DAC with discrete multibit fractal-7 matrix DA converter mainly intended for driving (pre) amps.

This device comes with a built-in power supply that works with both 115V and 230V. It uses a 2-pole Euro 8 power connection. It features a 192/24 Toslink DAPI receiver with a low-jitter master clock, power LED, and locked indicator.

The RCA outputs maintain a fixed 1.7V rms output voltage, and there are no lossy analog circuits or components in the signal path. The device is compatible with headphones of 32 Ohms and above, and you can connect them using a suitable external attenuator. The housing is durable and anodized.

“New” digital audio interface

This new digital audio interface is backward compatible with the Toslink interface and S/PDIF protocol. It effectively eliminates unwanted jitter in the digital audio source, interlink, and all DAC circuits, even in the presence of significant crosstalk.

The interface ensures low noise and low jitter, improving the sound quality of existing Toslink DACs. The transmitter side (digital audio source) connects to a coaxial cable through an RCA connector. At the cable's end, there's an optical connector compatible with the Toslink input on the DAC. This setup combines an electrical interface (low jitter) and an optical interface (low noise, eliminates ground loops).
