The ApplePi Volume-Clocker allows you add hardware volume control to any RapsberryPi I2S DAC.

Volume is controlled by a potentiometer R15. Volume is adjustable from 0 dB to -127.5dB, in 256 steps.

In addition to HW volume control this board will also remove jitter from the RapsberryPi's I2S signals improving audio quality.

It can be powered externally though it's own micro USB (X6) connector or from the Raspberry Pi. The ApplePi Volume-Clocker cannot back power the Raspberry Pi.

Specs:

  • Dynamic Range: 144 dB (–60-dbFS Input, 20 Hz to fS/2, A-Weighted)
  • THD+N: –140 dB (0-dbFS Input, BW = 20 Hz to fS/2)
  • Supported Resolutions: 24-bit, 20-bit, 18-bit, and 16-bit
  • Supports sampling rates up to 212 kHz
  • No drivers required.

The ApplePi Volume-Clocker can be added to any reward level for $79 USD, except for the touchscreen one. It can also be purchased separately for $79.

ApplePi DAC Tour

Postby orchardaudio » Tue May 08 2018 14:01

The ApplePi DAC went on a tour around the country. Here is what people who have tried it, have to say:

Wayne - Littleton, CO
"This is a very well engineered and built DAC. I again suggest folks sign up for the tour and listen yourself." and "I spent a good week listening to it and came away extremely impressed with what Leo has done with this DAC hat."

Alan - Harrisburg, OR
"I have had the Apple Pie for a while and I must say I am really impressed." and "Any way this is a dammed fine budget setup that punches way above it's weight."

Sharschchandra - Austin, TX
"The build quality is top notch and I really like the layout." and "The unit sound great out of box, very organic, almost neutral and full bodied (compared to ES9038PRO based DACs). The vocals were amazing especially on the JBL 4312B monitors."

Jerry - Camarillo, CA
"This is one sweet little Dac, Leo. I actually left work early today just to spend more time getting to listen." and "You have one helluva nice piece here; I appreciate the gracious demo."

The tour continues to this day, and will continue beyond Kickstarter. If you would like to sign up, go here: https://www.audiocircle.com/index.php?t ... msg1665901

Orchard Audio ApplePI DAC review

I bought one of the early versions of this DAC that were sent out for review and I have to say I'm very happy with it. The production DACs provide the option of powering RPi and DAC either separately or with a single supply. Mine didn't give that option so initially I powered the combination with a single iFi iPower supply. I heard a very well-resolved ,spacious and detailed sound with firm bass and extended treble. The downside was that it was just a bit fatiguing to listen to on some material and front-to-back depth was a bit limited.
I then realised that I could power the RPi and DAC separately by stacking my IsolatorPi in between them. The combination of separate supplies and isolation definitely improved things to the point where I was preferring it to my current fave, the Terraberry DAC2. Adding the Allo Kali to the stack was the icing on the cake but of course the cost of that whole combination is then in Katana territory.
RPi 2b // Terra-Berry DAC2 // Hypex UcD180 // Bi-amped OBs with Visaton B200, Goodmans 15", Neo3 tweeters.
