Looks like I'll have to go stealth. On good info, I've heard this show will be NO AUDIO/NO VIDEO allowed. This complicates things as I'm not sure how to "stealth". I'll figure it out, I guess. I'll need the luck.
Its not so hard - can you practice beforehand on a local band?
I recommend:
-lots of 'dry runs' to familiarise yourself with the equipment.
-check connections are tight (and stay that way), and that you have levels in both channels.
-I mount the mics on a stiff collar, facing towards the speakers, however this is up to you, do whatever you are comfy with. IMO people do not spot those tiny mics, particularly if you wear lots of black clothing.
I run mic leads down inside of T-shirt to battery box (clipped on waist), and battery box lead to Nomad in jacket pocket.
-Set the Nomad to no EAX, no remote, low volume, no gain required. Turn off the backlight, it'll suck juice.
-Take the following: Mini maglite
-Optional: mirror to check mic position (I kid you not), friends to block you either side, earplugs.
-Don't let the Nomad overheat, ventilate it a little.
Good luck!
