I am in a situation where a UHF mic is being used to transmit audio to a speaker with a built in receiver. In this case, the speaker in question is a Pyle PPHP1241WMU. The actual transmitter has no branding or model number, but I found that the frequency is marked as 662.6 MHz.
What I'd like to do is be able to record the audio from the mic to an external device using a separate receiver. However, I don't know what frequency is needed or even what to buy. Shedding any light on the situation would be appreciated. Thanks!
