It has advanced technology, stable performance and exquisite design. The 64MHZ bandwidth brings better transmission performance; the volume gain is adjustable in 1dB steps. Three levels of RF power are optional, and multiple levels of SQ are available. The microphone is equipped with a TFT display, so the device status is clear at a glance. It is fully suitable for high-demand KTV, multi-function halls, hotels, conference rooms and small and medium-sized performance venues.

Functional Features

64MHZ system bandwidth

The system has an ultra-wide bandwidth of 64MHZ, which is wider than similar products on the market. Even when multiple sets of equipment are needed for large-scale performances, there are still enough frequencies to choose from, making it easier to avoid interference during use.

Optional dual-bay chargers

Optional contact-type dual bay changer, simply place the microphone into it for charging. Utilizing rechargeable NiMH batteries, it offers a longer lifespan compared to alkaline batteries, ensuring enhanced safety, durability, and environmental friendliness. This convenient charging method is suitable for various scenarios requiring frequent charging.

TFT color display

TFT color display

It adopts a 1.14-inch TFT high-brightness display with rich colors and high visibility. It is easy to grasp the working status of the device and clearly displays the frequency, power, dB value, lock/unlock and other status.

SQ multi-level adjustable

The multi-level SQ value can be adjusted freely, and the mute threshold can be adjusted according to the actual use situation on site. It can ensure high-quality sound pickup regardless of short distance or long distance, and can be used in various occasions.
