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.
- Mae'r cyflenwad pŵer cyftage 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.
Gosod Ystafell Ddosbarth
Gosod Meicroffon
- Uchder Gosod: 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.
Gosod Siaradwr
- Uchder Gosod: 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.
Gosod Soced
- Gellir gosod panel soced dewisol gyda soced USB wrth ymyl y siaradwr i gael mynediad hawdd i'r meicroffon a'r siaradwr. Gall hefyd gael ei bweru gan addasydd USB neu ddefnyddio dyfais gyda rhyngwyneb USB yn uniongyrchol (teledu neu arddangosfa fawr, ac ati).
- Pan fydd y meicroffon a'r siaradwr wedi'u cysylltu â'r un plwg wal ar gyfer cyflenwad pŵer, mae angen troi'r meicroffon a'r siaradwr ymlaen neu i ffwrdd ar yr un pryd.
Gosod switsh
- Gallwch ddewis panel switsh sengl, wedi'i osod ar ochr y drws neu'r bwrdd du, gyda label, yn hawdd i athrawon ei agor a'i gau.
Problem ac Ateb
- Howling appears at startup
- Am gynample, mae'n arferol i'r meicroffon chwibanu ychydig pan fydd newydd ddechrau. Pan fydd y ddyfais newydd ddechrau, mae angen iddo ddysgu addasu i'r amgylchedd maes sain byw, a bydd yn stopio'n awtomatig ar ôl i'r dysgu gael ei gwblhau.
- udo parhaus
- Am gynample, 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.
- Nid yw'r atseiniad sain yn glir
- 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.
FAQ
Can I use the microphone without connecting it to a PC?
Yes, you can use the microphone in standalone mode by connecting it to an audio output device using the provided cables.
Beth yw'r cyflenwad pŵer a argymhellir cyftage ar gyfer y meicroffon?
Mae'r cyflenwad pŵer a argymhellir cyftage is DC 5V when using the USB interface for power.
How can I improve the speaker experience when using active speakers?
It is recommended to use low-latency active speakers for a better speaker experience.
