Oscillation mode PLL Frequency Synthesis
-
Frequency range 640-690MHz
-
Continuous use time 6-10 hours
-
Continuous use time 6-10 hours
-
Receiving mode Superheterodyne Secondary Frequency Conversion
- Using automatic human hand detection technology, the microphone will automatically mute after the hand leaves for 3 seconds(any direction and any angle), automatically save energy and enter the standby state after 5 minutes, automatically shut down and completely disconnect the power supply after 15 minutes; the microphone will be muted when it is falling on the ground.
- Using a new audio circuit structure, it provides delicate treble, powerful alto and bass; it is perfectly expressive in the details of the sound; super dynamic tracking ability makes the sound pickup flexible in far and short distances.
- The new digital pilot technology solves the problem of mutual cross-frequency in KTV private rooms.
- With squealing suppression circuit.
- Automatically search for the channels without
- Flexibly set the number of times of use.
- Use UHF frequency band and PLL frequency synthesis.
- Adopt super heterodyne secondary frequency conversion design, with extremely high receiving sensitivity.
- The RFadopts multi-stage high-performance dielectric filter, with excellent anti-interference ability.
- The first IFadopts a SAW filter, and the second IF adopts a three-stage ceramic filter, greatly improving the anti-interference ability.
- The specially designed mute circuit completely eliminates the impact noise when turning the microphone on and off.
- The microphone uses 2 AA batteries, which can last for 6-10 hours.
- The microphone adopts a unique boost design; the decrease in battery power does not affect the overall performance of the
- With adjustable transmit power and adjustable squelch threshold, the rear panel of the receiver is equipped with an external squelch control knob, and the effective operating radius can be flexibly set between 10 meters and 80 meters according to actual
- With an infrared automatic frequency matching function, the microphone can be quickly synchronized to the working channel of the receiver.
- KTV special model, two microphones+ one receiver, unique structure design, convenient maintenance, easily covers more than 100 KTV rooms.
