Description
20 Segments VU Meter Module LED Audio VU Meter Audio Analog VU Meter Yellow LED Display Volume Module
Product Description
VF series vu LED bargraph meter modules can accept and interpret audio signal and programme signal which is transmitted by lines and generate audio level for display. The module can achieve vu volume meter's bar display or dot display and level's peak hold is optional. Sensitivity of transmission channel can be adjusted by the parts on module, so display's dynamic range can be adjusted easily. Audio input can connect the signal to the preamplier(circuit) or power amplier output port by PH port connector or other two connectors. The signal is sent to the LED bar to display after mean detection, transfer amplication and processed by software. Because of wide impedance match range, the module can be widely used in the display of audio system's audio output, sound console output, programme signal transmitted by lines and volume output by power amplifier. The module has wide range power supply, low power consumption. The bargraph can be a single color, such as red, green, yellow etc. or can be two or more colors to display separately, which represent different function region and improve the visual effect of programme.
