Welcome To Our Company Online Store - MiCWL Audio Inc.
with AD2 KSM8 Handheld Singing Voice Speech Microphones
Features:
1. True diversity receiver, dual-channel independent selection system. It can minimize the occurrence of frequency interruption.
2. The dual-channel independent AFS frequency automatic search function can quickly scan and lock the frequency with the least
worry in the working environment.
3. Receiver and transmitter use IR infrared frequency matching technology to synchronize codes with one click.
4. Professional performance-level phase lock circuit, combined with noise lock squelch control and digital pilot technology, when
the transmitter is turned off, the pilot control mutes the AF signal to suppress noise, and at the same time mutes the
corresponding receiver. It guarantees the effective blocking of the worry signal.
5. Backlit LED display indicates the working status of RF and AF signal strength, battery status, diversity channel indication
(A/B), frequency, frequency group/channel, etc.
6.Accurate electronic volume control technology, the receiving distance is adjustable in three gears, and has an operation key
lock function to prevent misuse.
7. TRD.3 true diversity wireless system is specially designed for touring and fixed installation purposes, and provides a variety
of sound heads with different sound properties for replacement. It has the highest reliability, sound quality and transmission
stability.
