MASSIVE 500M OPERATING RANGE: Experience unshakeable signal stability with an impressive 300-500 meters line-of-sight range, powered by true diversity UHF 610-670MHz technology.
400 ADJUSTABLE CHANNELS: Features robust PLL digital phase-locked loop technology. Supports up to 20 systems (80 microphones) operating simultaneously in the same venue without crosstalk.
PRO 4-CHANNEL RECEIVER: The sleek console includes dual large LED displays for real-time frequency monitoring, 4 separate SQ potentiometers, 4 balanced XLR outputs, and 1 mixed output.
PREMIUM KSM8 HANDHELD MICS: Includes 4 high-fidelity mics with unidirectional condenser cores for exact sound restoration. Powered by AA batteries, delivering up to 12 hours of continuous use.
VERSATILE FOR PRO AUDIO: Employs advanced ambient noise rejection and a signature blue LED light ring on the mics. The ultimate choice for massive stage singing, large corporate meetings, and lectures.
Professional True Diversity Performance: The AD4Q system delivers pristine audio for singing, conferences, and live events. With 400 user-adjustable UHF channels and 4 × KSM8 handheld condenser microphones, it ensures clear, noise-free transmission over 300–500 meters.
▸ 400-Channel Flexibility: Each of the 4 independent receivers offers 100 selectable channels (250 kHz spacing / 24.75 MHz per channel). Up to 20 systems (80 transmitters) can operate simultaneously on the same stage without interference.
▸ Stable PLL Digital Synthesis: Advanced phase-locked loop digital lock-phase technology paired with chip-based circuitry ensures exceptional frequency stability of ±0.001%, eliminating drift and dropouts in demanding environments.
▸ Flexible Transmitter Pairing: No longer limited to a single channel per transmitter — each handheld can be paired across all 400 channels within two receiver banks, offering unmatched setup versatility.
▸ Wide Frequency Range: Operates across the UHF 610 MHz – 670 MHz band with FM modulation, delivering a signal-to-noise ratio exceeding 60 dB and total harmonic distortion below 0.5% at 1 kHz.
▸ Exceptional Range: Achieves 300–500 meters in open-space conditions and 80–200 meters in complex environments, powered by 4 rubber receiving antennas on the rear panel.
▸ High Dynamic Range: With ≥100 dB dynamic range and >80 dB adjacent-channel rejection ratio, the system maintains clean audio even in RF-congested venues.
▸ High-Fidelity Condenser Capsule: The KSM8 features a unidirectional (cardioid) condenser element with a frequency response of 40 Hz – 20 kHz, capturing every vocal nuance with outstanding clarity and minimal noise.
▸ Sensitivity & Power Efficiency: Rated at -43 ±3 dB @ 1 kHz with a power consumption of only 80 mA, each mic runs continuously for up to 12 hours on 3 × AA (1.5V) batteries.
▸ Patented Design with Status Indicator: The unique patented housing includes a blue light ring that illuminates during operation, making it easy to monitor mic status at a glance.
▸ Comprehensive I/O: Rear panel features 4 independent SQ potentiometers, 4 balanced XLR outputs, and 1 mixed unbalanced output, compatible with mixers, amplifiers, and recording interfaces.
▸ What's Included: 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.
