The AD4Q 4-Channel UHF Digital Wireless Microphone System is a flagship professional wireless solution engineered for large-scale events and demanding live audio environments. Designed specifically for stage performances, band gigs, houses of worship, school auditoriums, and corporate conference rooms, this system includes a sleek 1U rack-mountable receiver and 4 premium KSM8 handheld condenser microphones. Featuring 400 user-adjustable UHF channels (100 per receiver), PLL digital phase-locked loop technology, and an impressive 300–500 meter line-of-sight range, the AD4Q delivers pristine, dropout-free audio that competitors simply cannot match at this price point. Each mic runs up to 12 hours on AA batteries, with a signature blue LED status ring for real-time monitoring—making this the ultimate all-in-one wireless solution for any professional audio setup.[reference:0]
Each of the 4 independent receivers offers 100 selectable channels (250 kHz spacing, 24.75 MHz per channel), totaling 400 user-adjustable UHF frequencies across the 610–670 MHz band. Up to 20 systems (80 transmitters) can operate simultaneously on the same stage without crosstalk, making this ideal for large-scale musicals, multi-act festivals, and multi-room conference centers.[reference:1]
Each KSM8 handheld features a high-fidelity unidirectional (cardioid) condenser capsule with a frequency response of 40 Hz – 20 kHz, capturing every vocal nuance with outstanding clarity and minimal noise. Rated at -43 ±3dB sensitivity @ 1 kHz with only 80 mA power consumption, each mic runs continuously for up to 12 hours on AA batteries. The patented housing includes a signature blue light ring that illuminates during operation for at-a-glance status monitoring on dark stages.[reference:3]
The rear panel features 4 independent SQ potentiometers, 4 balanced XLR outputs, and 1 mixed unbalanced output, providing full compatibility with mixers, amplifiers, and recording interfaces. Unlike fixed single-channel systems, each handheld can be paired across all 400 channels within two receiver banks, offering unmatched setup versatility for changing stage configurations or multi-room events.[reference:4]
The AD4Q ships as a turnkey solution with everything needed for immediate professional use: 1 × 4-channel digital receiver, 4 × KSM8 handheld microphones, 1 × 1/4-inch audio cable, 1 × universal AC-DC adapter (110V / 240V), 4 × antennas, and 1 × user manual. The receiver features dual large LED displays for real-time frequency monitoring and a sleek 1U rack-mountable form factor that integrates seamlessly into any existing audio rack setup.[reference:5]
