Quote Exavior Music:
Okay, if the band are coming from "Aux Sends 1", then you want to connect the IEM to "Aux Sends 2". That way you can use the Aux 2 knobs to do your own mix, as you will want it to be different to the rest of the band I expect.
Wot 'e said!
Now this "pre-fade" business... for each input channel on your mixer, it's best to have the 'pre' button engaged for auxes 1 & 2. This means that the output is 'pre' the fader for that channel. So, if in the middle of a piece the soundtech decides to pull back the fader on, say, a guitar input, then that won't affect the sound in the monitors or the in-ears. So you use the individual channel prefade rotary control to determine how much of that signal is sent to the auxiliary output. Moving the fader won;t affect the monitor sound from those auxiliaries at all.
Just had a look at the manual for your IEM system... looks like you can set it up as a mono system so you may be OK with feeding only one of the inputs on the transmitter.
... and now something you haven't asked about... a licence to use it. The goood news is that you won't need a licence as long as you run it on a frequency between 863.001 MHz and 864.999 MHz. Anything else either needs a licence or is (or soon will be) illegal to use in the UK. If you gig at places where there are other radio mics in use, you may need to check that there's no frequency-clash with any of their systems and maybe adjust accordingly. (There are issues about how many separtae devices you can use at the same time in that band (Channel 70) but we'll leave that for now.)
The older I get, the better I used to be
