Suitable places: 

banks, office halls, hospitals, petition offices, border control, reception, prisons, interrogation, airports, classrooms, examination halls, companies, museums, auction houses, and other places that need to restore sound and record history.

Usage: 

Installation near the surface of the sound source, must expose the microphone's sound picking hole on the surface of the object or wall, wide range of sound collection should be installed in the centre of the room, four sides, balanced sound collection.   

This type of product needs to provide sufficient voltage and current, ordinary are 12V100MA DC power supply, requires good filtering performance with a voltage regulator transformer to provide, cable transmission distance can be up to a few thousand metres,

the thicker the cable, the farther the transmission, the case of AC interference, please use shielded cable (non-video cable) transmission.

Working Principle:

 The electret microphone with large diaphragm converts the sound signal into a weak electrical signal and transmits it to the highly sensitive audio preamplifier, which contains a noise attenuator, a sound reduction processing circuit,

 and an amplifier circuit to ensure that the amplitude of the output sound signal is high enough, with little noise and a long transmission distance to truly restore the sound of the scene.

Pickup installation location selection:

 pickups are generally suitable for installation on any flat surface, including the ceiling, side walls or directly fixed to the desktop or under the table. Try to be as close as possible to the main sound source.

Note:

 the best separate wiring, do not use the same cable slot with AC and other strong power, while trying to stay away from transformers, 

lamps and lanterns rectifiers and other strong electromagnetic interference equipment. Audio cable and power cable should be routed separately to avoid current interference.

Notes:

 1. Please compare the detailed size with your size, please allow 1-3 cm error due to manual measurement.

 2. Due to different shooting angles and light angles, the product color may have a slight color difference. This is a normal phenomenon. Please understand.

 3. If you have any questions about your purchase, receipt or non-receipt, you can contact our customer service center customer service staff, we will try our best to solve the problem for you!
