12-level indicator LED light bar VU meter stereo amplifier (A)

12-level indicator LED light bar VU meter stereo amplifier (A) Description

12-Level Display LED Light Bar VU Meter Stereo Amplifier (A) Description
1. Minimal volume, PCB size: 80 x 14 mm, LED module area: 58 x 14 mm
2. Thanks to the extensive functions, the user can freely adjust the actual speed of light of each individual light bar and the main light to optimally match it to their display.
3. The audio input is signal-isolated via TI to avoid high-frequency interference of individual chips in a series-connected audio circuit as much as possible.
4. A current-limiting resistor is provided for different light colors. A perfect combination.
Important Note:
1. The MCU performs a sampling time measurement, so the two-channel, simultaneously parallel input signal changes rapidly. The amplitude of the two light strips is displayed; this is normal.
2. In extreme cases, very slight high-frequency noise may occur. It is recommended to replace the signal input cable with a two-core, shielded cable.
3. Operating voltage: 7-12 V, current over 100 mA. Forbidden or voltage exceeding 12V, positive and negative reversed, regardless of whether the person causes light damage.
