AM6409 Intelligent Wireless Microphone System

Features

● Brand-new audio circuit architecture delivers delicate highs and powerful mid-low frequencies, with exceptional detail and clarity. Outstanding dynamic tracking capability ensures stable and natural sound pickup at both long and short distances.
● Innovative digital pilot tone technology completely eliminates frequency interference between adjacent KTV rooms — no cross-frequency interference ever.
● Built-in feedback suppression circuit for easier system setup and tuning.
● Automatic interference-free channel scanning for convenient installation.
● Maximum output volume can be freely limited for flexible application.
● UHF frequency band with PLL (Phase-Locked Loop) frequency synthesis.
● 100 × 2 channels with 250 kHz channel spacing.
● Superheterodyne dual-conversion design with extremely high receiving sensitivity.
● Multi-stage high-performance dielectric RF filters for excellent anti-interference capability.
● First IF uses SAW (Surface Acoustic Wave) filter; second IF uses triple ceramic filters for enhanced interference rejection.
● Specially designed mute circuit completely eliminates turn-on and turn-off pop noise.
● Powered by widely available AA batteries, with 6–10 hours of continuous operation.
● Unique voltage-boosting design ensures consistent performance even when battery power decreases.
● Ideal operating radius up to 80 meters under optimal conditions.
● Default configuration includes LCD display with blue backlight and aluminum alloy microphone body.
● Adjustable RF transmission power and adjustable squelch threshold. Rear-panel external squelch control knob allows flexible effective operating range adjustment from 10m to 80m.
● Infrared automatic frequency synchronization enables quick channel pairing between microphone and receiver.
● Specially designed for KTV installations. Standard configuration: two microphones and one receiver. Easily supports deployment in over 100 KTV rooms. Unique structural design allows fast and simple maintenance.
● Applications: Suitable for high-end KTV rooms, small to medium-sized performances, classrooms, conference rooms, and similar venues. A key new product of the year, highly favored by customers. Packaging: Standard color box packaging (see product brochure for details).
