Product Description

Straight out of Japan, an excellent and well over the top I2S DAC designed around the Asaki Kasei AKM4490 DAC. The Terra-BerryDAC 2+ is a no-compromise high-end RaspberryPi I2S Audio DAC, the successor of the praised Terra-Berry (which was in absolute my favorite I2S DAC). The Terra-BerryDAC 2+ features a no-compromise design in every detail.

It includes:
– Terra-Berry DAC2+ PCB
– M2.5 11mm spacer x 6
– M2.5 nut x 4

This is the only DAC equipped with the I2S DoP decoder, this means it can play DSD over PCM via I2S. It also features an integrated micro-controller, which can be used to fine-tune this DAC to its best potential. So, it’s not yet another I2S DAC: this is the most advanced I2S DAC for Raspberry PI (but can be used also standalone, by connecting it to a USB to I2S receiver) available and its extended configuration capabilities makes it ideal for the ones looking to fiddle and tweak their DAC.


  • Raspberry Pi HAT compatible, GPIO I2S connection
  • Powered by AKM AK4490 DAC PCM
  • Playback up to 768KH/32bit PCM and DSD up to 11.2MHz
  • Two low jitter Crystal oscillator for Master Clock (45.158400MHz and 49.152000MHz)
  • Re-clocking and up sampling by AKM AK4137 SRC with onboard MCLK oscillator
  • Onboard I2S DoP decoder by AK4137
  • Independent power circuit for DAC VREF
  • Automatic MCLK selection by LRCLK frequency
  • Balanced / Unbalanced output
  • Independent DAC power input connector
  • Combo384 support

Advanced Configuration Options

This DAC can be accessed via serial port, to configure various parameters like: hardware volume control, hw equalizer, hw resampling, filtering ecc

The DAC is accessible via /dev/ttyAMA0

Communication parameters:

Every command must start starts by ‘.’ and enter <CR>
Resposnse from DAC starts by ‘:’

For the complete list of command refer to AKM4490 Datasheet and the TerraBerry Command list
