2. Adopting professional audio compression-expansion technology, it has low noise, small tail tone and larger dynamic range.
3. Applying PLL RF stabilization technology, the frequency is accurate and the work is stable and reliable.
4. It has independent output (XLR) and mixed output (_6.3mm), which makes it easy to connect audio processing and power amplifier equipment.
5. Infrared frequency matching, interchangeable transmitter, simple operation and advanced function;
6. With 8-level radio frequency level display, 8-level audio level display, channel menu display, silent display;
7. Balanced and unbalanced output ports are selected to meet different equipment connection requirements.
8. Super anti-jamming ability can effectively suppress noise interference and co-frequency interference caused by external.
9. Search the free channel automatically and avoid the interference channel automatically.
10, medium frequency rich, sound and magnetic and thick feeling, is the essence of human voice microphone quality.
