Features:
- 8 channels receiving signals, each channel has 50 signal channels to select, and each channel is stepped by 250KHz; For each channel is 49.75MHz;
- Stable PLL digital phase-locked loop synthesis technology and chip circuit are adopted to significantly improve the stability of the overall performance;
- UHF band transmission signal, frequency range: 500MHz-690MHz;
- The same occasion can be used for 5 sets of machines at the same time, that is, 5 receivers and 80 transmitters can be used at the same time;
- LCD screen displays working channel, working frequency point, received signal and audio signal;
- 4 rubber receiving antennas are set on the back of the receiver to enhance the received signals, and the appearance is elegant and decent;
- 8 balanced outputs, 1 mixed unbalanced output and 1 mixed balanced output on the back, suitable for connecting various external devices;
- It is no longer limited to a single channel that can only be paired with one transmission, and the same transmission can be interworked in 400 channels of two channels. Interoperability and humanization of high-tech design;
- The power consumption of the microphone is 80 mA, powered by 1.5V batteries (3pcs), and can be used continuously for 12 hours;
- The microphone is equipped with a blue light ring to indicate the working status of the conference microphone (the light ring displays blue when working);
- Use distance: Open environment: 80-100m ; Complex environment: 50-80m
- Suitable for all kinds of meetings and presentations.
