Generally in the live performances, studio and other important occasions,Be sure to use the true diversity of products received in order to ensure that the practical operating distance does not produce dead spots, to overcome the frequency off.True Diversity Features:1. True diversity dual microphone four receive, effectively overcome the frequency off dead ends, UHF band, PLL digital frequency synthesis.2. Infrared frequency, the transmitter can be interchangeable, simple operation, advanced features.3.300 frequency points to meet the 100 KTV rooms used at the same time, high sensitivity to meet the outdoor distance to meet the performance requirements.4. Each stack frequency, simple operation, for the user to provide more convenience.5. High-quality microphone core, high-fidelity output, so that your voice sound transmission. Close to the level of high-fidelity cable microphone level, so that your voice is fully restored.6. Automatically search for free channels, automatically avoid interference channels.SystemType of SystemTrue Diversity UHF Wireless Handheld SystemRF Carrier Frequency RangeUHF780 - 830MHzDynamic range110dBOverall Frequency Response35Hz ~ 20KHz ± 3dBSignal-to-Noise Ratio> /- 115dBAThe total number of channels100 × 2 = 200Effective distance200 ~ 300 (depending on the scene may be)ReceiverSensitivity-100dBmOscillation methodPLL digital frequency synthesisSignal to noise ratio90dBDistortion0.5%Battery Type/Approx.
