Next level Active DSP Crossover

There are automated setup scripts -> https://github.com/HEnquist/camilladsp-setupscripts but depending on your specific hardware / OS they may not work correctly.



Yes. My main system consists of an Okto dac8 pro + RPi4 running CamillaDSP + Apple TV. I don't switch sources and only use the Apple TV as a source. Switching sources is relatively easy, typically done by changing CamillaDSP configurations which can be done via remote. Biggest issue with source switching is potential need to change the clock source / operating mode of the DAC.

The Apple TV remote is capable of turning the Okto (via IR), TV (via CEC) and Apple TV (via bluetooth) on/off and controls volume of the Okto. The Okto has a standby mode and will automatically turn on when it senses a signal, it also has a trigger out which turns on 4 amplifiers. After 10 minutes of inactivity, it goes back to standby, and the amplifiers shut off.

My office system uses a MOTU Ultralite Mk5 + RPi4 running CamillaDSP + Apple TV. Again, I don't switch sources here. I use a FLIRC IR USB device to control CamillaDSP volume and an OLED display for volume indication. This setup uses a Bobwire DAT1 and the optical output of the MOTU to provide trigger input to 3 amplifiers. Like the Okto setup it will turn on automatically if a signal is sensed and will turn off in about 1 minute of no signal.

Both remotes work great and will detect commands even if not directly aimed at the device via bouncing.

Hi Michael,

Could you please elaborate a little on your RPi4 setup running CamillaDSP? I'm mainly interested on the interfaces you use on the Pi for digital input and for output to the Okto DAC.

Thank you,
Sergiu

The Okto has a USB / AES mode designed to route the AES inputs to a USB host (in my case a RPi4 running CamillaDSP) and then back to the Okto for D/A conversion. More detail can be found here -> https://github.com/mdsimon2/RPi-CamillaDSP.

These days I no longer use CamillaDSP with the Okto but rather the Okto AVDSP firmware -> https://github.com/fabriceo/AVDSP_DAC8. This eliminates the RPi from the setup (other than loading filters) and all processing is done within the Okto itself. This is much less powerful than the RPi4 / CamillaDSP setup but works for my purposes.
