    J-909U UHF Professional High Band Wireless Microphone  

System Features:

Products of thie series have various outstanding features, including large LCD display, demonstrable working frequency and AF volume indication.

1. Simultaneous output: imbalance 1/4" headphone plug and balance XLR output connector can be plugged to different external equipment simultaneously.

2. Coverage scope: KS-series transmitter's maximum coverage scope is 30 meters to 100 meters from the receiver (regarding to different transmissions)

3. Noise constraint: The squelch circuit analyzes the strength of the signal while analyzing the quality, thus effectively reduces the impulse train of the RF noise in the environment.

4. Low-battery warning indicator: The red light on the bodypack or handheld microphone turns bright to warn the user that the batteries have ess than one hour usage time.
