Description
Product Overview
The DigiOne Signature is the ultimate digital transport for Raspberry Pi audio enthusiasts, designed for those who demand absolute clarity, ultra-low jitter, and exceptional signal integrity. Building on the legendary DigiOne, the Signature version takes digital perfection to the next level with a two-board design, enhanced decoupling, onboard supercapacitors, and fully isolated circuitry.
With separate “dirty” and “clean” power domains and support for multiple power supply options, the DigiOne Signature ensures uncompromised audio performance from your Raspberry Pi streamer. It’s the perfect choice for audiophiles seeking a bit-perfect, jitter-free digital transport.
Features
- Re-clocker Technology – Uses its own precise clocks for ultra-low jitter, independent of Raspberry Pi timing.
- Galvanic Isolation – “Clean side” board is fully isolated from the “dirty side” to reduce noise and interference.
- Dual Power Supply Design – Requires two power sources:
- Dirty side: 5V / 2–3A (Raspberry Pi supply)
- Clean side: 5V–6V / 100mA (batteries, linear PSU, or high-quality SMPS)
- Ultra-Low Jitter – Measured jitter below 400fs at the buffer stage.
- High-Fidelity Outputs – Coaxial and BNC outputs with 1ns rise/fall time and precise 550mV voltage level.
- Included Accessories – 2 × DC to Type-C adapter cables for easy setup.
- Broad Compatibility – Works with Raspberry Pi 3, 4, and 5.
- Old Driver Support – Compatible with existing DigiOne drivers; simply select DigiOne on your favorite audio player.
Note: The DigiOne Signature requires two power supplies to function. For optimal audio performance, we recommend using a high-quality linear supply or battery pack for the clean side. While you can power both sides with a single PSU, this is not recommended for the best listening experience.
