Multi-classroom simultaneous use of non-serial frequency ｜ Broadcast Priority Access ｜ Handheld/Lover dual-purpose wireless microphone
Specially built for multimedia classrooms in primary and secondary schools, 50W high-power two-frequency wooden box, 2.4G digital radio frequency anti-interference; Microphone comes with laser pointer and PPT page turning. Compatible with campus broadcasting system, wall hanging and hoisting dual-purpose, large-scale campus projects prefer sound reinforcement equipment.
Covering the main teaching space of the campus and supporting the standardized batch deployment of the whole school.
The teacher gave a lecture with a wireless microphone, and the sound box was hung on both sides of the classroom. The voice was clear and loud, and the students in the back row could hear clearly.
Ladder lecture hall, multi-function hall wall-mounted sound reinforcement, speech, report, event host voice full coverage.
Daily teaching sound reinforcement, teachers are not laborious, classroom sound evenly covered.
Training lectures, lecture reports, activity hosts, voice clearly convey the whole audience.
Multi-classroom batch deployment, thousands of sets of equipment in the same field without serial frequency, management worry-free.
From wireless transmission to vocal restoration, technical basis supports every value.
2400-2483.5MHz 2.4G digital radio frequency technology is adopted to effectively avoid transmission interference. At most 1000 sets of equipment can be operated at the same site at the same time, without serial frequency and mutual interference, which is suitable for the construction of batch projects of the whole school. The external integrated hidden 2.4G signal receiving box has no exposed antenna, avoiding electromagnetic interference inside the speaker, and improving the sensitivity and stability of signal receiving.
Equipped with broadcast priority interface (70V-110V constant voltage broadcast input), when the campus broadcast signal is connected, the equipment automatically switches to give priority to broadcast broadcast notification, and the two systems of class and campus broadcast coexist without manual switching.
Rated power ≥ 50W,4Ω impedance; 5.5-inch long stroke bass unit treble unit divide-by-two design, frequency division point 1.8KHz; Phase reflection wooden black box body, steel net cover; Sensitivity 85dB/1W/1M, signal-to-noise ratio 75dB, restore clear voice.
1 channel of 70-110V broadcast priority input; 1 channel stereo RCA audio input, docking teaching all-in-one machine, computer audio output; 1 channel microphone input interface, with DC 6V power supply, can be externally connected with wired microphone.
Also using 2.4G digital radio frequency, automatic pairing when starting up, and prompt tone when pairing is successful; Built-in pickup head, can be hand-held; With 3.5mm external microphone interface, it can be externally connected with collar clip microphone and head microphone to realize collar clip mode teaching.
The microphone is equipped with an intuitive LED-LCD display screen to display digital volume, signal strength and remaining power in real time. It has a windproof sound pickup structure and clean sound quality. Integrated laser pointer, optional module can realize PPT wireless page turning and one-key black screen functions.
The microphone automatically enters the energy-saving standby without signal/no operation for 60 seconds, and automatically wakes up when the signal is detected, reducing power loss; the detachable interface rechargeable lithium battery, working continuously for ≥ 8 hours in a fully charged state; equipped with a travel/USB charger; boot with a prompt Tone, support body digital volume adjustment.

Use matching wall hanging accessories to complete wall hanging or hoisting and fixing; Connect the power supply and connect RCA audio of campus broadcasting and teaching integrated machine.
When there is a broadcast signal on the 70-110V broadcast line, the audio will automatically give priority to the broadcast, and the broadcast will automatically switch back to the teaching audio.
The audio of the teaching integrated machine is connected to the RCA port; when an external wired microphone is required, the MIC interface is inserted.
When the microphone is turned on, it will automatically enter the pairing state, and a prompt tone will sound when pairing is successful, and it will enter the receiving working state.
The built-in microphone can be used to give lectures in hand. The 3.5mm interface is externally connected with a collar clip/headset to switch the teaching mode of the collar clip.
Laser pointer pointing courseware; The optional page turning module realizes PPT page turning up and down and one-key black screen.
Idle 60 seconds automatic standby; operation, sound signal automatically wake up; body button to adjust the microphone volume.
Use the matching USB charger to charge the microphone lithium battery, and charge it as you use it.
