Product Overview
The AD4Q 4-Channel UHF Wireless Microphone System with Beta58 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 Beta58 dynamic supercardioid handheld 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.
Key Features & Benefits
🔹 4× Beta58 Dynamic Supercardioid Mics — Legendary Vocal Performance
Each handheld features the industry-standard Beta58 supercardioid dynamic cartridge, purpose-built for lead vocalists. The tight supercardioid pattern emphasizes vocal presence while effectively suppressing off-axis noise and feedback—critical for loud stages with floor monitors. Delivers rich, natural vocal reproduction from 50 Hz–16 kHz with proven reliability on world stages. Each handheld operates up to 12 hours on 3× AA batteries (80 mA consumption), with a signature blue light ring for at-a-glance status monitoring on dark stages.
🔹 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.
🔹 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.
🔹 Supercardioid for Maximum Feedback Rejection on Loud Stages
The Beta58's supercardioid polar pattern provides a tightly focused pickup area directly in front of the microphone, with excellent rejection of sound from the sides and rear. This means less stage monitor bleed, lower risk of feedback, and cleaner mixes—essential for bands with wedge monitors, loud backline amplifiers, and high-gain PA systems. The dynamic transducer handles extreme SPL without distortion, making it ideal for powerful vocalists.
🔹 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 × Beta58 dynamic handheld microphones, 1 × 1/4-inch audio cable, 1 × universal AC-DC adapter (DC 12V–17V), 4 × antennas, and 1 × user manual. The receiver features a large LED display for real-time frequency monitoring, 4 independent SQ potentiometers, 4 balanced XLR outputs + 1 mixed unbalanced output, and a sleek 1U rack-mountable form factor that integrates seamlessly into any existing audio rack setup.
