1.Using multimeter to measure audio monitoring’s DC power voltages, requirement of voltage between 8v and 18V.
2.If you have more audio monitorings, can compare their cross wiring, to confirm the failure from audio monitoring or wiring or other complete set of equipment.
3.If the audio line connect to other audio equipment, please disconnect and directly connect to the walkman earphones/computer’s ordinary active speaker system to test. If the sound is normal, it explains that audio monitoring has no problem, please check the audio equipment or other aspects.
4. Connection is in good condition and reliable or not.
5.Whether amplification equipment interfaces match with audio monitoring or not, the sound volume of amplification equipment appropriately adjust or not.
6.It is strictly prohibited to connect to microphone input end (MIC) of sound card or sound console or power amplifier devices, otherwise may damage the equipment. Because audio monitoring contains microphone too, and it also contains amplification, noise reduction and echo processing circuit, output "Line Out" audio signal more than 1 VPP.
(1)The audio monitoring cannot be used with switch power supply, please use the high quality of 12v DC regulated power supply. You can choose our high-quality power supply or adapter.
(2)If the audio line connect to other audio equipment, please disconnect and directly connect to the walkman earphones/computer’s ordinary active speaker system to test. If the sound is normal, it explains that audio monitoring has no problem, please check the audio equipment or other aspects.
(3)Checking whether caused by sound self-excitation or not. The loudspeaker used on monitoring must not too close to audio monitoring, and don't test as far as possible in the same room. Due to the audio monitoring is high sensitivity, the voice of loudspeaker fed back to audio monitoring microphone, it will inevitably cause squealing sound. If need to monitor in the same room, you can use the walkman headphones.
(4)When wiring, you have better to separately cabling, do not use the same cable trough with alternating current or strong current. At the same time, as far as possible away from transformer, rectifier of lamps and lanterns or other strong electromagnetic interference equipment.
(5)It is strictly prohibited to connect to microphone input end (MIC) of sound card or sound console or power amplifier devices,otherwise may damage the equipment. Because audio monitoring contains microphone too, and it also contains amplification, noise reduction and echo processing circuit, output "Line Out" audio signal more than 1 VPP.
(6)Some video monitor with own loudspeaker, but may have a poor effect, please use the middle or high-grade earphones or active speakers system for monitoring.
(7)The integration sound card quality of some computer mainboard is bad, it will cause serious noise when recording, please change to use brands of high quality sound cards.
(8)Check the volume of audio monitoring’s sound gain potentiometer or amplification equipment whether adjust appropriatly or not.
(9)Some brands of audio distributors are not high quality, it will cause voice cracking,etc., please choose high quality distributor or our brand audio monitoring adapter .
(10)Some model hard disk video recorder only focus on the video processing and ignore the audio processing, it may cause the voice of the synchronous video recording quality become low. Please disconnect the connection, and then directly connect to audio line with high-quality headphones or active speaker to test. If the sound quality is very good, you can determine that the audio monitoring quality is no problem.
