The LS - 949.
UHF800MHZ four-way wireless meeting microphone
Use the UHF740-840 MHZ band, to avoid interference.
The transmitter is equipped with high and low power adjustment and volume adjustment.
Meeting the goose pole adopts aviation plug, not afraid to loose.
Using multilevel narrow-band high frequency and medium frequency narrowband filtering, fully eliminate the interference signal.
Using quartz oscillation circuit, high frequency stability.
Using high frequency compression extension technology, greatly reduce the noise and dynamic range.
There is the function of doping call down less, can effectively reduce the lost call back.
Receiver using multilevel high frequency amplifier has a very high degree of sensitivity.
Noise level locking double mute control, noninterference more machine used at the same time.
Has a balance and imbalance way audio output.
Wide frequency response range. Low distortion.
