I have a GL2400 installed in a venue for live bands. I typically mix with instrumets, vocals and effects routed to subgroups, then to L&R. The main L&R outs go to my PA. I also send a matrix mix of the subroups out to a delay unit and then to the house sound system.
This setup works great when the bands are playing. The problem I've run into is when the band takes a break I need to play CDs. I have a CD player plugged into one of the stereo channels on the board. The problem is at the low volume the CDs are played I can't get a strong signal out of the matrix, even if I crank the L&R matrix mix all the way. (The signal to my PA at the desired volume barely registers on the main output meters.)
Does the Mic Out on the stereo channels only send out the XLR signal, or does it also pass the stereo inputs? I'm thinking I could split the signal there and route it back into the matrix.
Otherwise, I may have to patch the CD player into two mono channels. I could then take the direct out on both of those channels and route them back into the matrix.

Lots of questions. How are all the levels set? What is the exact routing, all the way from the console inputs to both the main PA and remote system inputs? If the band is routed to groups, groups routed to matrix and LR, and LR routed to matrix, the band is double routed to the matrix, so it will be louder. How many places in the signal path have level control? How different does the balance between rooms need to be? It seems OK for band, not for CD. Since the group to matrix route is loud enough, why not route the CD through the groups?

When the band is playing I cut the LR matrix mix so they aren't double routed. The remote feed needs to basically be the same level when the band or CD are playing.
The CD is played at a fraction of the volume the band is played. When the band is playing the output meter on the board peeks just below 0. However, the desired volume for the CD barely registers on the meter. There just isn't enough signal going to LR or the subgroups when the CD is played.

Sounds like you need to adjust your gain structure and maybe turn down the overall level at the amps rather than with the console output. If your L/R outputs are much lower in level than the groups then that would cause the problem noted and may be an indication of a less than optimal gain structure.

The gain structure wasn't the problem. The outputs, both LR and Matrix, are great when the band is playing. The CDs are just played MUCH quieter than the bands so routing out of LR didn't have a strong enough signal.
Thanks for your input though!

That's because with a band you have a lot more signals mixed together.
