Wireless Microphones
Handheld wireless microphone — 200-channel UHF, diversity reception.
SR-66C Handheld pairs the SR-66C diversity receiver with a handheld UHF transmitter mic in a single package. The system offers 200 selectable UHF channels with true diversity reception and 14 hours of battery backup. Its AFS system incorporates a synchronisation channel between microphone and receiver, with channel selection and the associated frequency performed at the receiver and synchronised to the microphone instantly through an IR signal. The receiver’s front panel features a potentiometer for volume control, two channel/frequency buttons, and a confirmation button, with a large high-brightness LCD showing RF and AF levels alongside the selected channel and frequency.
