Complex harsh environment 250m Range (Rainy days are included)

1. True diversity, 2 Channel wireless handheld microphones, short circuit protection function; infrared automatic frequency matching, pilot frequency function Four antenna signal strengthened reception (multi-level high-frequency filter design has strong anti-interference ability and no noise)

2.1U standard chassis, metal panel, LCD liquid crystal display display working status, simple function operation.

3. High-fidelity audio transmission circuit, anti-drop, anti-vibration microphone core matching, sound clarity and high vocal reproduction.

4. Hand microphone power consumption: 110MA, using imported DC conversion boost circuit low power consumption and high efficiency, effectively extending the battery life. Radiant power: 16mW, use distance up to 500 meters in open environment. Complex harsh environment Rainy 200m Range.

5. Use multiple squelch control circuits on the receiver to effectively prevent external signal interference. 300 channels (A channel 001-150, B channel 151-300), no serial frequency or frequency drop when using multiple sets. Suitable for long-distance projects, large and small performances and other occasions. 5. Equipped with anti-switch impact function to ensure the protection of the output of the rear stage, and prevent the power amplifier and speakers from being impacted and burned.

6. The hand microphone has a battery level display, and the receiver also has a battery level display, which is convenient for remote monitoring of battery usage and working status at a glance.

 

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.
