Product Description

Orchard Audio’s ApplePi DAC is the most advanced and highest performance sound card hat for the Raspberry Pi.

For less than $250 (ApplePi + Raspberry Pi) you can achieve performance currently only available at $750+ USD. In addition, ApplePi DAC eliminates the need for pre-amplifiers, saving even more money.

The ApplePi DAC was designed from the ground up to offer commanding performance (see specifications below). Using the latest packaging technologies, ApplePi DAC became a reality. Performance was verified on a state of the art audio analyzer from Audio Precision.

Putting It Together

This video shows how to assemble an ApplePi DAC with a Raspberry Pi.

This video shows you how to install an operating system on to your Raspberry Pi’s SD card. The ApplePi DAC already has a driver built in that will automatically get detected by Raspian on bootup.

This video shows how to connect power to the ApplePi DAC and Raspberry Pi.

This video shows how to use the fully assembled ApplePi DAC System with and without a touchscreen.

NOTE:

Due to power consumption, it is highly recommended to use a 5.25V power supply when powering from the Raspberry Pi or other SBC.

 

ApplePi Volume-Clocker Install / Usage

To install the ApplePi Volume Clocker onto the Raspberry Pi you will need the following:

  • 4 x 14mm M2.5 Standoffs
  • Stacking Header

Install the stacking header in to the ApplePi DAC’s connector X1. Install standoffs on the Raspberry Pi and then plug the ApplePi DAC w/ stacking header onto the Rapsberry Pi.

Power Options:

  • Power from Raspberry Pi
  • Power from Micro-USB connector (X6) When powering the board from the Raspberry Pi the J2 shunt (jumper) needs to be installed. This is the default setup and the boards are shipped with J2 shunt in-place. When powering from the Micro-USB connector (X6) the J2 shunt must be removed.

Note 1: The ApplePi DAC cannot back power the Raspberry Pi.

ApplePi Volume-Clocker Install / Usage

To install the ApplePi Volume Clocker onto the Raspberry Pi you will need the following:

  •  4 x 12mm M2.5 Standoffs

Install the standoffs on the Raspberry Pi and then plug the ApplePi Volume-Clocker onto the Rapsberry Pi.

Power Options:

  • Power from Raspberry Pi
  •  Power from Micro-USB connector (X6)

When powering the board from the Raspberry Pi the J2 shunt (jumper) needs to be installed. This is the default setup and the board is shipped with J2 shunt inplace.
When powering from the Micro-USB connector (X6) the J2 shunt must be removed.
Use R15 for volume control – turn clockwise to increase volume – turning fully counter clockwise will mute the device

Note: The ApplePi Volume-Clocker cannot back power the Raspberry Pi.

ApplePi Volume-Clocker Pinout

All connections are passed though the ApplePi Volume-Clocker to a DAC hat expect for the I2S signals.
