100% brand new and high quality

Features:
The feature-rich, user can freely adjust each light bar and the main peak of the real speed of light, with the most suitable for their own display.

Audio input through the TI original signal isolation, the maximum to avoid the single-chip high-frequency interference to an audio circuit in series.
Different colors of light alone provided a current limiting resistor. Guarantee a perfect match.

Important note:
1. MCU in the sampling time-sampling, so that there is dual-channel simultaneous parallel input signal changes fast, the amplitude of the two light bar display may vary,

this is a normal situation.
2. In extreme cases, there may be very slight high frequency noise. Recommended to replace the signal input line head position as dual-core shielded cable.
3. Operating voltage: 7-12v current can work in more than 100MA. Prohibited or voltage exceeds 12v positive and negative reversed, whether the person will cause light damage level.

Display effect:

1. strip show + after peak travel whereabouts
2. strip show after + the disappearance of the peak travel
3. The strip display + (no peak display)
