Please Read Before Purchasing:
- Audio signal is taken from a 3.5mm conventional headphone jack, or connected in parallel with the input signal of audio device. Generally we call it a low-level signal, and the volume of audio device must be set to the maximum volume, and the low volume cannot be used. Can not be connected to a car speaker cable, can not be connected to the output end of power amplifier! Wrong connection will cause product damage! If there is no headphone jack nor other connectors, please purchase an adapter (cable) separately. It cannot be used in an environment with audio Bluetooth transmission. This product has only line input, and there is no voice control.
- This product is for professional electronic enthusiasts to modify power amplifiers and other products. Non-professional electronics enthusiasts or users who have no ability to modify please not buy it.
- This product is for DIY use. If you don't have electronic knowledge nor hands-on ability, please think twice before purchasing.
- Please refer to the figure below for product wiring diagram.
Features:
- PCB size: 105*10mm. LED module size: 82*10mm.
- Power supply voltage: DC 7V-12V. Please power the product independently. Power supply current: No less than 50MA. It can be more than 50MA.
- Front end audio signal must be connected. Connection to power amp output is prohibited.
- Software adjusts the original real-time mode to a professional DB mode, which has a professional reference function. It can be installed in professional related equipment for signal monitoring. The functions and effects of the original AGC mode remain unchanged.
