Product Overview
The AD4Q 4-Channel UHF Wireless Microphone System with KSM9 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 KSM9 dual-diaphragm condenser handheld microphones with switchable supercardioid/cardioid polar patterns. 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.
✨ Premium KSM9 Condenser Upgrade: This system features the KSM9 dual-diaphragm condenser capsule — a significant upgrade from the KSM8 dynamic capsule. The KSM9's Class-A discrete transformerless preamplifier, dual 3/4" gold-layered Mylar diaphragms, and switchable supercardioid/cardioid polar patterns deliver studio-grade vocal clarity, exceptional detail, and precise articulation that discerning lead vocalists and professional presenters demand. Frequency response: 50 Hz–20 kHz.
Key Features & Benefits
🔹 4× KSM9 Dual-Diaphragm Condenser Mics — Studio-Grade Vocal Reproduction
Each KSM9 handheld features premium dual 3/4" gold-layered Mylar diaphragms with a switchable supercardioid/cardioid polar pattern — the first handheld condenser microphone with this capability. The Class-A discrete transformerless preamplifier delivers pristine 50 Hz–20 kHz frequency response with exceptional vocal subtlety and clear articulation. Rated at -43 ±3dB sensitivity @ 1 kHz with only 80 mA power consumption, each mic runs continuously for up to 12 hours on 3× AA batteries. The patented housing includes a signature blue light ring that illuminates during operation 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.
🔹 Switchable Polar Patterns — Adapt to Any Acoustic Environment
Unlike fixed-pattern microphones, the KSM9's switchable supercardioid/cardioid polar pattern provides unmatched flexibility: use supercardioid for maximum feedback rejection and isolation on loud stages with floor monitors, or switch to cardioid for more forgiving pickup in conference rooms, houses of worship, and acoustic environments where a wider pickup area is preferred. One microphone adapts to every venue—no need for multiple mic types.
🔹 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 × KSM9 condenser 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.
