The Fosi Audio ZD3 brings digital audio sources into a clean desktop or home stereo setup with the control of a DAC preamp and the output flexibility of balanced and single-ended connections. Use USB for a computer, HDMI ARC for a TV, optical or coaxial for digital components, or Bluetooth for wireless playback. XLR and RCA outputs make it easy to connect the ZD3 to compatible power amplifiers, powered speakers, or downstream audio gear.
High Resolution DAC Performance
The ZD3 uses a chipset built around XMOS XU316, ESS 9039Q2M, QCC3031, and LME49720 components. USB playback supports PCM 32bit/768kHz and DSD512, while optical and coaxial inputs support PCM 24bit/192kHz. For listeners building a compact hi-fi chain, the ZD3 helps keep source selection, conversion, and volume control in one focused desktop component.
Flexible Inputs And Outputs
Multiple inputs support common audio sources across desk, TV, and stereo systems. HDMI ARC helps route TV audio into a two-channel system, while Bluetooth 5.0 supports aptX HD, aptX, AAC, and SBC audio formats for wireless listening. Balanced XLR outputs deliver 5Vrms, and RCA outputs deliver 2.5Vrms for connection to compatible amplifiers and audio systems.
Designed For System Control
A 1.5-inch OLED display gives clear feedback while the infrared remote control supports convenient operation from a listening position. The 12V trigger in and out connections help coordinate power control with compatible audio equipment. A preamp bypass mode provides fixed-level output when the setup calls for direct signal transmission, and the swappable op amp design supports users who want to tune their audio chain with compatible DIP8 dual op amps.
