Hope someone can help, can't find exactly my situation.
I have a Mackie proFx16 v3 which has 3 × 6.3 mm (pre fader switchable) Aux sends. (Well 4, but one of them is dedicated to Fx.)
My band is currently using 2 × active floor monitors – i.e. 2 monitor mixes, one fed from Aux send 1 and 1 fed from Aux send 2. All works fine, but there's the usual issues of too much noise on stage and occasional feedback issues.
We want to move to in-ear monitoring but still with 2 “mixes”, one shared by myself and a singer and another shared by 2 guitarists/singers. I'm planning on achieving this by buying 2 x SHURE PSM 300 in-ear monitoring systems, each with 2 bodypack receivers. So one for 1 mix shared by myself and vocalist (AUX 1) and the other shared by the 2 guitarist/singers (AUX 2) - hence 2 body pack receivers with each transmitter, which is not a problem.
The problem I cannot find a definitive answer to is the best way to hook up each PSM 300 transmitter to the mixing desk from the relevant Aux output – i.e. what cable? Each Aux send on the desk is just one 6.3 mm output, but there are 2 (combo xlr/jack) inputs on the back of the Shure PSM 300 transmitter, Left & Right. It would seem to me that as there are 2 inputs it would be best to use them both, but...
Would it be best to get a TRS jack to 2 × 6.3 mm jacks cable, or simply a mono jack to jack cable feeding just one input on the back of the PSM 300? (There's a note in the PSM300 manual which says: Important: When connecting to only one transmitter input, use the LEFT/CH1 input. Set the transmitter to MONO to hear audio on both channels)
I'm not sure whether the Aux output of the Mackie mixer is Stereo, Mono or balanced mono, and frankly whether it makes a difference in the real world. I don't need to hear “stereo” in the ear monitors, but do need the sound to come through both earpieces, not just one.
I've tried researching online and ended up going off at tangents detailing TRRS (rather than TRS) cables etc. which is just confusing me.
Any comments/suggestions very welcome!
