Pioneer DJM 900 as DAC?

Postby felixheller » Sun Mar 17 2019 10:11

Hello,
I am having a Pioneer DJM 900 in my living room as a mixer for my turntables and would love to use the buildt in DAC with volumio, i think it should have 4 integrated stereo lines which could be used but if i connect it to volumio none of them show up, any ideas how I could get it working?


thanks for any ideas!

Just looking at the spec of the DJM900, there's a number of ways you could get to talk to it, but... how are you connecting to it? USB, S/PDIF, RCA ? What are you connecting from? These details would need to be filled out before any suggestions could be made...

I've gone looking through Pioneer's specs and 'documentation' on this thing and can find no trace of what DAC they're using. Without that, It's not going to be easy/possible to provide an appropriate driver for the mixer. All I can see is that it's either 32bit or 24bit (depending on what you're reading), so not really useful. The possibility exists that it's all being done by the DSP in the middle of the mixer (for cost purposes), at which point I'd give up and try something else.

Sorry, I don't think this is going to be possible with so little information available. If it were an industry-standard DAC, then one of the Volumio devs might have been persuaded to tweak an existing driver but currently the DJM900 is just a black box...

Well, if you could connect it again and do
Code: Select all
lsusb
it might show us some more detail about the fact whether and how is is being recognized.
Also, the output of
Code: Select all
dmesg
may help.
Don't hesitate to ask if you need help with that.

Pioneer DJM 900 as DAC?

Hi Felix,

What @gkkpch is asking you to do follows on from the boot sequence that you've shown. What's needed is to use the command line of the Pi to enter the command lsusb and copy what gets reported. This is what my RPi shows (without any USB devices attached):

volumio@volumio:~$ lsusb
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
volumio@volumio:~$

and then again with dmesg. This command gives a large amount of info, so don't be surprised by the huge amount of text it produces,
