ADI-2-Pi 1.0.0

Network remote and audio bridge for RME ADI-2 series converters (ADI-2 DAC, ADI-2 Pro / Pro EX, ADI-2/4 Pro SE) on a Raspberry Pi with Raspberry Pi OS Bookworm or Trixie.

Features

  • Web interface for all output, input and device settings, parametric EQ, bass/treble, loudness, setups and the unit's 20 EQ presets
  • WebSocket/HTTP API (docs/API.md), reference client clients/adi2pi-client.js, mDNS service _adi2._tcp
  • Volume limit per output, rise-speed limit, linked volumes
  • Bluetooth A2DP in both directions on the built-in adapter (LDAC, aptX HD, aptX, SBC-XQ, SBC)
  • Network receivers: AirPlay (AirPlay 2 optional), UPnP/DLNA, Squeezelite, Snapcast; Spotify Connect and Roon Bridge as install options
  • Source arbitration (newest source or mix), sample rate follow or fixed, automatic output Source switching to USB during playback
  • Headphone EQ Generator for ADI-2 and TotalMix FX Room EQ with bundled oratory1990 measurements (AutoEq)
  • Optional shutdown with the ADI-2: USB connection lost, or 12 V Trigger Out on a GPIO
  • Waveshare UPS HAT (B/C/D/E): detected by the installer; battery and power on the System tab, shutdown on battery
  • Volume of AirPlay and Spotify Connect senders sets the ADI-2's volume (optional)
  • Start volume: outputs turned down to a set level when the unit is switched on
  • Scenes, actions on events (Bluetooth device, playback start/stop, time of day, unit on), sleep timer
  • Backup and restore of unit settings, EQ presets, setup names and bridge settings
  • Optional access key for the API and the web interface
  • MQTT with Home Assistant discovery
  • Optional update check (off by default): shows when a newer release is on GitHub; nothing is downloaded or installed
  • Quick levels: volume buttons per output
  • Headphone profiles: EQ, bass/treble, loudness, crossfeed and a volume limit per headphone, applied to any output; shared with apps and MQTT
  • Actions on: a digital input getting or losing its signal (Pro models), the Pi being idle for a set time; time actions with an end time and a second scene
  • Access key "changes only": the page and the state are visible without the key, changes need it
  • Now playing: title, artist, album and play state from AirPlay (with cover art), Spotify Connect and Bluetooth, on the Pi Playback tab, in the API and as an MQTT sensor
  • Web page in English and German; other languages as one JSON file each (web/lang/README.md)
  • No npm dependencies; no external resources at runtime

Installation

tar xzf adi2-pi-1.0.0.tar.gz

Requirements

  • Raspberry Pi (tested: Pi 4), Raspberry Pi OS Bookworm or Trixie
  • Node.js 18 or later (installed by the installer)
  • ADI-2 connected by USB with MIDI Control = ON
