Teacher looking for help with professional AV installation: lav mic broke
I’m not an AV tech, but a teacher at a university. One of our lav mics broke in a presentation hall, and we’re trying to replace it in time for an important course next week. Official support does exist but would take long and is quite flaky, because this system was originally installed by a third party. We have contact with the original installer, but in the meantime we’re just looking for a quick fix.
The details of the system:
The transmitter where the mic is plugged in is a wireless AKG PT470 transmitter. (Mini XLR input). This connects with a AKG SR 470 receiver and ultimately an RCF AM1000 MK2 Series P.A Amplifier.
We currently have a Sennheiser HS2 headband style mic which works fine, but we need a lav mic for the upcoming course.
We’ve received an Omnitronic MOM-10BT4 lav mic from the institution earlier, but this one is very quiet (unusable), even with the gain control on the receivers put on the highest. Did we get an incompatible mic? Is something wrong with our settings? The same exact settings and hardware worked fine for our previous lav mic (which unfortunately was taken away, so we don’t know the model) or the HS-2 headband style mic.
What kind of other lav mic can we buy? What are the specs we should look out for to see if it’s compatible?
