I want to pass something along in case anyone's interested.... My band's PA is modest (we play mostly acoustic-type stuff and pop, e.g. Eagles, at volumes that don't make your ears bleed) but we need monitors for three-part harmonies. Not wanting to buy or lug yet another amp and yet more speakers, a while back we bought a wireless monitor system. It was the then-current Carvin unit, which is pretty much the same as the Nady. It worked and served its purpose, but it had a really severe compressor built into it that stomped all over the signal, making it hard to hear ourselves clearly. We just suffered along. Last night at rehearsal we tried an experiment: We used a headphone distribution amp that we have for our small recording studio setup instead of the wireless. Holy eardrum, Batman!!! It sounds MUCH MUCH MUCH better. We also added an ambience mic (just a mic that just picks up room sound). A little bit of that in the mix further improves things. In the monitor mix we have the three vocals and a bit of guitar. Drums (in our case provided by a machine) and bass come through the ambience mic as well as directly into our ears (we use some Sony walkman-type headphones that hook over your ear and don't fit too tightly in the ear canal, so we can hear some outside sound...we don't see the point of running at damaging levels so we don't need earplugs). The downsides: 1) MORE wires to trip over on stage, dammit! 2) Can't adjust volume at your belt. 3) Can't move far from the mic (mostly because of tangling wires...they're as long as our instrument cables). 4) No limiter to protect us in the event of a dropped mic, etc. (however, this may not be as dangerous as it would otherwise be because we don't use form-fitting earpieces). The upsides: 1) The monitor mix sounds better than the mains! 2) No worries about batteries. 3) We can turn down the monitors because they're so much clearer. 4) Way cheaper than wireless, even the cheapo rig we had. 5) Still a heckuva lot easier to tote around than floor monitors. If you're considering in-ear monitors, try it...you can get a decent distribution amp for not much more than $100. The headphones we use are ten bucks a set, and the extension cables six bucks each. BTW, it's also a great way to get the g***arist to turn down... just feed a little bit of the guitar into the monitor mix. He'll get it right in his ear, so he can turn it down and still be heard very clearly.
