Ive got a master room xl305 that id like to use for stereo but the left channel is too noisy so id like to use the right only. Is there anyway I can get the right output signal to go to 2 channels on my mixer so I can use stereo? Thanks

Hmm, perhaps you could patch the working channel to a mixer channel, then take the direct out to a new channel...but hard panning two copies of the same reverb channel, expect to end up with a "big mono" sound more than "stereo"....
 
I wouldn't split the signal like that. You'll weaken the output and wind up with more noise. You can technically do it with a y cable, but I wouldn't. Plus it's going to be in mono anyway.
 
Exactly. Either way you end up with "big mono," more noise and a wasted mixer channel.
 
Thanks. I would use in stereo but I get this ridiculous amount of noise on the left channel.

Your mixer has that function built in. It's called a pan pot.
 
you can theoretically turn a mono signal into an ersatz stereo using a digital or analog delay and slightly delay the second run of the right signal patched as briank suggested and use that as an artificial left, or get a comb filter like the Orban stereo synthesizer. It gives the impression of stereo.

For the trouble you could open up the box and figure out why you are getting noise, cold solder joint maybe, bad capacitor? Or, how critical is it to have stereo reverb? I"m not familiar with the piece of gear, but hte schematics are posted here:

Which, if he gets it, may help the OP realize why splitting a signal into two channels of the board will also not make it stereo.

Do you dare open and look inside? It could need some new caps or a cleaning.

Or one of the springs has broken loose. It was actually easy to break a spring connection in an Accutronics tank by dropping or jarring the amp it was in.
 
I think it might need to have the caps replaced. Im not too sure. The left channel sounds really noisy. Through the headphones it sounds kinda like wind. Windy noise...
I found the schematics but they are like Chinese to me. I have opened up the reverb and I didnt see anything wrong in there. The reverb i have sounds amazing with vocals but for some reason that left channel is just giving me problems.
 
Allen if you want, snap a good close up pic of the inside of the left channel and post it. You never know, someone may notice something.

I know that sound you're talking about. I wonder if it's a grounding issue. Might have an open end somewhere. Whatever it is it's fixable. Check your input and output jacks on the L channel and see if they need to be grounded.

It's also possible they shouldn't be grounded. So I'd just check them.

How can I tell if its grounded or not?

You should see a connection to the chassis somewhere. But now I'm just suggesting to check the jacks. If you can loosen them and try free floating them so they are not touching the chassis. See if the noise goes away. It's just something to try if it's easy enough to do. I really don't know if that's the problem.
 
I'll check her out tomorrow and post pics. Do you have any new recorded songs? :D

Just some cover demos of my duo I recorded on the Ampex. :D But I put together about 5 songs I'm going to record, including redoing some of the others.
