TOPIC: How is I2S implemented in the ICE 125 and 250?

How is I2S implemented in the ICE 125 and 250? 4 years 2 months ago #15038

mikefleming2 Offline Fresh Boarder Posts: 3 Karma: 0	I would like to know where in the signal chain the I2S is located. Specifically, can I incorporate an USB to I2S digital input and can I incorporate a separate DAC via I2S? Thanks, mike

If you want to do a USB input, easiest would really be to use something like a miniStreamer (USB to SPDIF) to basically feed it to the AES-EBU input (SPDIF works fine there). DevTeam

mikefleming2 Offline Fresh Boarder Posts: 3 Karma: 0	Dev, Thanks for the reply. Page 12 of the manual shows an I2S I/O header, which is why I thought that the unit had I2S. What is that used for then? Thanks again, Mike

devteam Offline Administrator Posts: 7788 Thank you received: 904 Karma: 150	Mike, Sorry for missing your post... The answer is that it's for "future". That header isn't tested nor enabled in any places on the MCU firmware and DSP firmware. DevTeam

kwozniak Offline Fresh Boarder Posts: 1 Karma: 0	Dev, I am currently working on an active speaker project. I am wondering if there is any neat way to add FIR filtering to ICE. I suppose that I2S would be a good way to add miniSHARC. My requirement is to have an analog input to every speaker (unbalanced and balanced) and single analog to digital conversion. The speakers will be plugged to the standard multichannel AVR. Christopher

devteam Offline Administrator Posts: 7788 Thank you received: 904 Karma: 150	@ Christopher, Sorry but no FIR on this product. Easiest would be to do it externally (e.g. OpenDRC-DI) and feed AES-EBU to the speakers. I2S won't be enabled for a while and complete different clocking so miniSHARC + PWR-ICE is very unlikely. External implementation (i.e. OpenDRC-DI) will be plug&play and already works. DevTeam
