Product Description
UR-280 Dual-channel diversity wireless microphone system is a wireless microphone system condensed from the essence of Relacart many years of technology. 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
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.
Anti-accidental touch switch
The handheld microphone uses a toggle switch and is located at the tail to prevent accidentally touching the switch during use, which may cause interruptions in performances, meetings, etc.
RF power multi-level adjustable
The RF power is available in three levels, Compared with other products on the market, there are more choices. Short-distance transmission can reduce power consumption, and it can also easily handle situations where long-distance transmission is required.
