Trantec 4000 IEM systems

I tried today to use my system with two separate channels - not stereo. We have comms fed normally to channel 1, set to mono - so all the receivers get the same on both earpieces. We wanted to feed radio mic audio to the person backstage who runs video and acts as Sound 2 - but the crosstalk is really bad, the radio mic audio is reduced on 'stereo' operation, but nowhere near the level I expected. Each channel leaks into the other - the amount being about the same as pulling a fader from unity to about half scale. Is this normal?

Yes.

 

In a word. Yes,

 

 

It really is that bad. But is BAD the right word. In its normal operation this is often a good thing as such wide stereo imaging straight to your ears can have unwanted effects.

 

I don't know of one (though I haven't really looked too hard) that has a complete SNR in channel 1 and 2 comparison terms of anything like what we'd expect for true separation.

I've got 8 of these systems, and they're all as you describe. I would estimate that there's no more than 20 to 30dB of separation between the left and right channels. I assume this a necessary design attribute to cram a stereo signal in to the available bandwidth.
