Wireless Monitoring Help
 

I'm using a comtek m72 with pr-72b receivers, feeding the transmitter from a balanced aux out of my mixer via balanced 1/4" converted to balanced 1/8" to feed into m72 Comtek transmitter input. On the receiving end from the pr-72b receiver headphones are only playing back in the left can.

Anyone able to help me understand why I can't get the Right/channel #2 signal from the mixer from the transmitter/receiver?

TY

Mono transmitter, mono output receiver. Plug stereo headphones into a mono output jack and you only get signal on the left channel. You need a 1/8 stereo jack to 1/8 mono plug adapter like this one from Radio Shack ... RadioShack Gold Series Stereo-to-Mono Audio Adapter - RadioShack.com

There is no such thing as a balanced 1/8 input so you're probably lucky anything is making it to the transmitter. AFAIK the Comtek input is an unbalanced TS jack. If your mixer is outputting on a balanced 1/4 TRS connection, wire the TRS-to-TS adapter cable with TRS tip going to TS tip, TRS ring to TS sleeve, TRS sleeve to the cable shield and leave the shield unconnected at the TS end (if you pick up noise you might also try connecting the cable shield to the TS sleeve - experiment to see which gives less noise pickup). DO NOT try to use a 1/4 TRS to 1/8 TS adapter plug similar to the one suggested for the headphones on the transmitter input - that will short the mixer's balanced signal hot to signal cold and result in silence.
