UHF True-Diversity Wireless Microphone System
ACT-290
Prevent crosstalk, each channel has a unique ID code, which prevents any interference source from entering the receiver.
With the world's advanced ACT (Automatic Channel Locking) function, the receiver's operating frequency can be locked automatically and accurately quickly.
The ^ housing is made of aluminium alloy and has the professional quality of break-free.
There are 8 color tail covers channel recognition;
High fax, wide range, high dynamic range, high quality, clear and bright super-centric directional midwick;
CPU control;
PLL frequency synthesis technology;
True Diversified Dual Receive Technology;
Large screen dynamic LCD display can display AF, RF level and channel conversion dynamically.
Channel ^200 is adjustable, so that multiple sets can be used simultaneously without interference.
The panel can set working distance, display mode and panel lock function.
