Product Details

T-530A UHF LCD Display FM Single Channel wireless classroom microphone for teaching

Features

* Adopt international standard EIA 1/2 width and 1U high metal chassis, which can be mounted directly to the rack.

* The use of ultra-high frequency UHF true diversity reception and multi-channel digital phase locked loop DPLL frequency synthesis technology;

* Provide 640-665M Hz and 100 frequencies 740-765MHz two each. Single-channel true diversity reception, avoid off-frequency phenomena and prolong the receiving distance.

* Super anti-jamming capability, can effectively suppress the noise caused by external interference and co-channel interference.

* LCD display window, channel, frequency, RF signal strength, antenna selection information action, AF audio output intensity, dynamic sweep.

* With infrared frequency transmitter frequency locked automatically synchronize ACT function.

* Rear receiving antenna separation design, true diversity dual antenna diversity receiver and the sound code, noise lock dual mute circuit, receiver distance, easily dropped.

* Internal SQ can increase receiver sensitivity adjustment to increase or decrease the sensitivity of the receiving distance in order to avoid noise interference.

* The receiver can be an external directional gain antenna system for increasing the reception distance and stable reception, the ideal state can be up to about 200 meters.
