XLR Question

You won't see this one every day....

I've recently converted a listening room to dual use - listening and recording.  I'm trying to use the 2 channel system as a monitor for the recording studio.

The 2 channel pre-amp is an Onkyo 5508 pre-pro (stereo mode) which has a set of stereo xlr balanced inputs available.  So, I want to take the output of my PC audio interface (Pre Sonus  Audiobox) into the Onkyo.

The Audiobox allows the PC recording system to connect to a monitor via balanced 1/4 inch trs out (phone plug). I got a trs to xlr cable and it works perfectly into a pair of active m-audio studio monitors.  However, no signal is evident when I connect the same trs-xlr cable into the Onkyo

Other than a faulty input on the Onkyo, any idea what might cause the monitors to work but not the pre-pro?

thanks in advance

According to the manual:


Connecting a Balanced Audio Source

You can connect a balanced audio source to the AV controller’s BALANCE L/R INPUT jacks by using two XLR audio cables. To use the balanced input, you must assign it to an input selector (➔ 47). If you connect a mono source, use the BALANCE L INPUT jack and set the “Input Channel” setting to “Mono(L)” (➔ 47). The AV controller’s balanced INPUT jacks are wired as shown.

Pay attention to:   To use the balanced input, you must assign it to an input selector (➔ 47).

Looks like you need to assign that input?
