Product Overview
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]
Key Features & Benefits
🔹 Advanced 4-Channel System Architecture with 400-Channel Flexibility
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]
🔹 PLL Digital Synthesis & True Diversity for Unshakeable RF Stability
Advanced phase-locked loop (PLL) digital lock-phase technology paired with chip-based circuitry ensures exceptional frequency stability of ±0.001%, eliminating drift and dropouts. True Diversity reception with 4 rubber receiving antennas delivers 300–500 meters line-of-sight range (80–200m in complex environments), with >60dB signal-to-noise ratio, <0.5% THD at 1kHz, and ≥100dB dynamic range—maintaining clean audio even in RF-congested concert venues and urban environments.[reference:2]
🔹 4 × KSM8 Handheld Mics — Precision Sound with Blue LED Status Ring
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]
🔹 Versatile Connectivity & Flexible Transmitter Pairing
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]
🔹 Complete Package — Ready for Professional Deployment
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]
