C24 Monitoring Issues

[Dondusko]

I just bought a C24 control surface for my setup. However, I'm having issues with the monitor section.

I'm just running Stereo, so I set the I/O to a Stereo Output called "MIX" on channel 1 for Left and 3 for Right.

I set the Monitor Section as follows:

Mode = Stereo L & R swiches are lit.
"Main" switch is lit on lower right.
Control Room is set to -24 dB

The issue is that it only willl output sound in the Left channel. However, if I engage the "Mono" button it will play in "Mono" in both speakers (Right also).

The other issue (much more baffling) is that the headphone plays in the Left channel fine, but the volume is much quieter in the Right.

I've checked the session to make sure it is panned properly and it seems correct.

I bought brand new digi cables from Sweetwater. I've checked that I connected the cables correctly multiple times.

I've done some research here, but there doesn't seem to be a definitive answer.

This is driving me a little crazy, so if anyone out there can offer some assistance, I'd be very appreciative.

Best Regards,
