The CTRLPA U788 is a true-diversity UHF wireless microphone system for long-range paging and live announcements in parks and emergency PA. Operating across 500–900 MHz with adjustable system sensitivity (−65 to −105 dBm), it delivers 40 Hz–18 kHz (±3 dB) audio, >115 dB SNR, ≤1% distortion, and >60 dB channel isolation. Transmitter runs ~6–8 hours continuous; receiver powered by 12 V DC / 1000 mA.
