Soundberry Audio Network Music Player with BAL/SE Output Headphone Amp

Raspberry Pi 4B installed with 32-bit/384kHz DAC + Headphone Amplifier with BAL and SE Output.

We have successfully integrated Snapcast multi-room synchronous audio player into moOde Player. From now on, every Soundberry Audio’s amplifier supports multi-room audio.

The DAC chip supports native 2-ch audio format: PCM 44.1/48/88.2/96/176.4/192/352.8/384 kHz (16/24/32 bit). The common file formats moOde Player accepts are MP3, FLAC, WAV, AAC, ALAC, OGG, DFF, DSF, and more other non-common formats.

Key Hardware Features:
- Galvanic isolated analog ground plane to keep noise from digital ground away
- Absolutely no 50/60Hz line frequency hums
- Inaudible background noise
- Internal I2S DAC driven by 2 very low jitter high precision master clocks (TCXO)
- Direct-coupled amplifier circuits with ultra low noise and ultra low distortion BJT input OpAmps plus high speed current feedback amplifier as output driver prevent odd order distortion anomalies
- Can drive Headphones with impedance ranged 32 ~ 600 Ohms
- Use very linear audio transformers to drive high impedance headphones
- Can drive 2 high impedance headphones simultaneously
- Amplifier has relay circuits for power-on delay and DC output protection

All our Raspberry Pi equipped amplifiers are pre-installed with moOde Player in the 32GB uSD memory card that shipped with the product. There is no need to install extra software. This left 26GB for music file storage.

The moOde Player OS provides a webapp for user control. Open a web browser page and enter either "moode/" or "moode.local/" whichever works. AirPlay, Bluetooth, and UPnP renderers are enabled by default. UPnP is used for streaming 24bit/192kHz from Qobuz. Squeezlite and Roon renderer are optional. With iPad or iPhone, you can stream music from Amazon HD Music App, YT Music App, or play your music stored in your
iPhone, iPad or Mac Computer by using AirPlay or Bluetooth. Or, you can insert your USB drive which stores your music files into one of the USB sockets at the rear panel.
