Product Information

ONE to rule your home audio. The only DAC you'll need!

The ZEN One Signature takes the DAC stage from the ZEN DAC V2, adds S/PDIF inputs (optical and coaxial) alongside the USB port, stirs in Bluetooth technology from the ZEN Blue V2, and seasons the pot with Signature-grade circuit enhancements to create a delicious audio brew.

The result? The ZEN One Signature is a pure DAC (no built-in headphone amp and volume control) that serves as a home audio hub for all your digital devices, from smartphones and tablets to PCs and Macs, disc players, and audio servers to TVs and games consoles.

Signature Special

The Signature series always includes extra special additions:

  • Low-jitter Femto clock crystal provides >20dB performance
  • 16 Core 2000MIPS XMOS low-latency microcontroller – 4x more processing power
  • C0G capacitors – high-linearity, excellent temperature/frequency characteristics
  • MELF resistors – high-precision and low-noise
  • Taiyo Yuden and Murata inductors – low-impedance power supply rails
  • High-gain antenna for extended range

Home Hub DAC

The ZEN One Signature is the first ZEN DAC to support all hi-res: DSD256, PCM384, MQA384kHz, Bluetooth 96KHz.

  • 96kHz Hi-Res Bluetooth: LDAC, HWA/LHDC, aptX Adaptive/HD/LL, AAC
  • USB audio using 16 Core 2000MIPS XMOS low latency microcontroller (MQA decoder)
  • Fully balanced 4.4mm output

Purity of design, no headphone amp, no volume control. The ultimate DAC for all your home audio sources.

Awesome Analog
