(Hand-held wireless transmitter T-52X, desktop wireless microphone T-52D)
Feature:
* Advanced PLL phase-locked loop frequency synthesis technology, CPU bus control system of microcomputer integrated central processor.
* Compatible with manually frequency selection and infrared automatic frequency locking channel, noise and sound code lock squelch control, more stable signal transmission.
* With SCAN automatic frequency scanning function. Press the SET key to automatically find out the cleanest frequency point and keep it as receiving frequency.
* The V/A screen is clear at any angle and can display channel number and working frequency, and supports 8-level RF display, 8-level audio level display, channel menu display, muted display
* Advanced filtering and anti-interference functions can effectively block the external interference of poor signals or phone signals.
* Use 640-830MHZ bands, each receiver has 200 adjustable frequencies.
* The traditional control button is more durable and affordable, built-in high performance voice companding technology, support both balanced and unbalanced output ports, better sound quality.
* Applicable to conference rooms, classrooms, banquet halls and other places.
