01 Introduction

Product Features FEATURES:

1. This machine comes with ten sets of preset frequencies, which can be called with one button, making debugging more convenient.

2. It has the function of automatically and quickly searching for clean frequencies, quickly finding reliable communication frequencies and avoiding interference

3. It has a one-button lock screen to protect settings and avoid misoperation. It has a one-button flying comb volume adjustment, which can independently adjust the volume to meet the needs of sound. The shuttle design avoids misoperation, making the project more secure, easy and efficient.

4. It has IR infrared automatic frequency matching technology, which can automatically achieve frequency matching and locking between devices with one button.

5. Due to the use of the same working frequency for each channel, the transmitters can be interchanged at any time, which greatly enhances the flexibility of operation. The conference/handheld/collar clip/head-mounted transmitter can be mixed and used.

6. The single-channel volume is independently adjustable, the single-channel audio output is independently controllable, four-way BALANCE independent output port, one-way MIX OUT mixed output port, and two optional output ports to meet the connection needs of different devices

7. The professional performance-level phase locking circuit, combined with the noise locking squelch control, ensures effective blocking of interference signals.

8. Super strong anti-interference ability, can effectively suppress noise interference and co-frequency interference caused by the outside, rich intermediate frequency, and magnetic and thick sound

9. With high-brightness full-view display screen, the receiver battery power real-time monitoring displays RF and AF signal strength, battery power, frequency, channel, etc. The transmitter real-time monitoring displays power, channel and frequency status.

10. The handheld adopts ultra-low power consumption design, uses two No. 5 batteries for ultra-long standby, and is easy to operate.

11. The high-configuration circuit is matched with the special dynamic microphone core to make the overall microphone noise clean and the sound quality transparent until the perfect effect is achieved.
