First, the conference system (paperless conference system) sound horns appear murmur or howling
1. The microphone (microphone lifter) has insufficient battery power or the amplifier volume is too large to cause noise. It is recommended that the user replace the microphone battery first or reduce the volume of the power amplifier appropriately.
2, Mike (microphone lifter) is too close to the speaker or facing the speaker is easy to produce howling, please adjust the distance and angle between the microphone and the speaker; the volume of the amplifier too large will also produce howling, adjustable low power amplifier volume try .
Second, the conference audio system microphone (microphone lifter) silent
1. Check if the microphone battery is dead; whether the wireless microphone receiver is powered; whether the connection between the receiver and the mixer is connected or loose
Third, the audio speaker does not ring
1. Check if the power amplifier is powered on or whether the power socket is powered. Users often turn off the power of the device when the system is turned off.
2. If the amplifier is turned on, check if the system is muted, or adjust the volume of the amplifier to be too low, so that the speaker is silent or the volume of playback is small.
3. If the amplifier is turned on, the volume is also adjusted, and the speaker still has no sound, then check if the mixer is powered off. The projector in the intelligent conference system is not lit. Symptom: The projector in the intelligent conference system is not lit. Solution suggestion: There are usually two representations of the projector that are not lit: A. The projector is not powered; B. The power is not projected.
Fourth, how to gradually check the conference system (ultra-thin one lift)?
Determine if the projector of the conference system is working properly
1: Is the projector's power switch turned on and the indicator light is on?
The indicator does not light after power-on, indicating a problem with the projector. Under normal circumstances, the hard switching power supply of the user's projector is long open, and the power indicator light is long. Among them, yellow light: waiting; green light: normal; red light: power up
2: Is the LAMP lamp and TEMP lamp long or blinking? (displays red)
A red light on the LAMP indicator indicates that the projector lamp is broken, reminding the user to replace the lamp. The red light on the TEMP indicator indicates that the projector is in an error state and cannot be projected. The projector is in self-protection or the hardware is bad.
3: Let the user connect the computer directly to the projector, does the projector project? Does the projector's port setting for the signal match? (If it is a VGA receiving port)
If the projector is not projected after connecting the projector directly, if the projector has a normal projection, it indicates that there is a problem with other related devices or cables connected to the projector.
