Re: IEMs, Singers and Occlusion
Between 1 and 5 ms, depending on the device model. By saying realtime, I was not intending to imply zero latency.
Many of these devices have an onboard preamp and are intended to be used much in the same way as a guitarist uses a stompbox.... Plug your mic into the box and send the output from the box to the PA. Fortunately the preamp in the TC boxes I have encountered seems to be of acceptable quality.
The cheapest offering seems to be the TC Mic Mechanic, which only costs $150. Musicians have been buying these things like crazy around here, and actually, they're a pretty decent little box. I actually bought one, and may buy more. The tuning is quite transparent sounding. Best if you can keep the box with you at the console though, rather than allowing a muso to fiddle with it!
