Scenario Installation Classroom
- For classroom installation, please refer to the figure below. The USB interface is used as the power supply port of the microphone, and can be connected to the socket or adapter with a USB interface.
- Lub zog mov voltage is DC 5V. The SPKOUT audio output interface is output to active speakers or power amplifiers through a 3.5mm audio cable.
- It is recommended to use low-latency active speakers first, and the speaker experience will be better.

Kev teeb tsa chav kawm
Kev Kho Mob Microphone Installation
- Installation Qhov siab: In theory, the closer the microphone is to the speaker, the better, but considering that it is too low, there may be a risk of students accidentally reaching out and hitting the speaker, causing damage or falling. principle, while considering security and flexible processing.
- Installation Method and Location: It is hoisted with a boom, and the position near the podium is centered horizontally, and the microphone disk facing the podium area, focusing on picking up the teacher’s lecture sound in the podium area.
Installation hais lus
- Installation Qhov siab: The recommended height from the ground is 2.0m-2.6m.
- Installation Method and Location: It is wall-mounted with brackets. It is recommended to install it in the middle and front of the walls on both sides of the classroom.
Qhov (socket) Installation
- Ib qho kev xaiv lub qhov (socket) vaj huam sib luag nrog lub qhov (socket) USB tuaj yeem nruab ib sab ntawm tus hais lus kom nkag tau yooj yim rau lub microphone thiab hais lus. Nws tuaj yeem siv tau los ntawm USB adapter lossis ncaj qha siv lub cuab yeej nrog USB interface (TV lossis cov zaub loj, thiab lwm yam).
- Thaum lub microphone thiab hais lus txuas nrog tib lub phab ntsa ntsaws rau lub hwj chim, lub microphone thiab tus hais lus yuav tsum tau qhib lossis kaw tib lub sijhawm.
Hloov Installation
- Koj tuaj yeem xaiv ib lub vaj huam sib luag hloov, nruab rau sab ntawm lub qhov rooj lossis lub qhov rooj dub, nrog rau daim ntawv lo, yooj yim rau cov xibfwb qhib thiab kaw.
Teeb meem thiab kev daws teeb meem
- Howling appears at startup
- Rau example, nws yog ib txwm rau lub microphone xuav me ntsis thaum nws nyuam qhuav pib. Thaum lub cuab yeej nyuam qhuav pib, nws yuav tsum kawm kom hloov mus rau qhov chaw nyob ib puag ncig lub suab, thiab nws yuav nres tau tom qab kev kawm tiav.
- Tsis tu ncua quaj
- Rau example, when the USB is connected to the computer, confirm whether the listening function is turned on, and check whether the audio input and output wiring are looped back.
- Lub suab reverberation tsis meej
- First, check whether the room is too small and the reverberation is too large, and then check the settings of the power amplifier or speaker EQ to see if the low-frequency part is adjusted too much.
