8 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 USB interface. The power supply voltage is DC 5V. The SPK-OUT audio output interface is output to active speakers or power amplifiers through a 3.5mm

interface audio cable. It is recommended to use low-latency active speakers first, and the speaker experience will be better.

9 Classroom Installation

9.1 Microphone Installation

1) Installation Height: 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.

2) Installation Method and Location: It is hoisted with a boom, and the

position near the podium is centered horizontally, and the microphone disk

is facing the podium area, focusing on picking up the teacher's lecture

sound in the podium area.

9.2 Speaker Installation

1) Installation Height: The recommended height from the ground is

2.0m-2.6m.

2) 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.

9.3 Socket Installation

An optional socket panel with a USB socket can be installed next to the speaker

for easy access to the microphone and speaker. It can also be powered by a USB

adapter or directly use a device with a USB interface (TV or large display, etc.).

When the microphone and speaker are connected to the same wall plug for

power supply, the microphone and speaker need to be turned on or off at the

same time.

9.4 Switch Installation

You can choose a single switch panel, installed on the side of the door or the

blackboard, with a label, easy for teachers to open and close.

10 Problem and Solution

1) Howling appears at startup

For example, it is normal for the microphone to whistle slightly when it is

just started. When the device is just started, it needs to learn to adapt to the

live sound field environment, and it will stop automatically after the learning

is completed.

2) Persistent howling

For 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 is looped back.

3) The sound reverberation is not clear

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.
