HW Volume Control and Reclocking

Postby orchardaudio » 04 May 2018, 15:04

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.

The Tour - Crisscrossing the Country

Postby orchardaudio » 07 May 2018, 14:12

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:
