Adjustable output sensitivity, for a variety of specifications header. -The most common 12VDC power supply, easy to use on in-vehicle device and PC computers. -With power supply reverse polarity protection. Provide energization pointer protection against boot pointer base, extend header life. -Use 0.5W metal film resistors, large power margin to ensure long-time reliable and stable working. Specification: Item Type: VU Meter Driver Board DB Audio Level Meter Input Sensitivity: 400Hz input audio signal with 8025B digital multimeter range measuring AC mV, input: 97mV, 39 level to + 3dB position. Power Supply Voltage: DC12V 0.12A PCB Size: 63x52x20mm / 2.48x2.05x0.79in Backlight Power Supply Terminals: Available DCl0 to 12V 50MA. Power for small bulbs backlighting. Drive VU Meter, Level Meter Sensitivity: Recommended 500uA sensitivity, 630 ohm resistance. At this time damping effect is the best, the other specifications level meter will be different in damping effect, need further adjustments. Description: The supply voltage must be strict to ensure 12VDC, although more than a short-term work, but a long time will burn protection circuit. Instructions: -Input Part: Lin, 0, Rin, is an audio signal input terminal for CD audio output connected to the left and to the right channel. Or an output terminal connected to the first input terminal selection stage, the former should not connected to the output stage output or volume potentiometer. -Output Part: Two VU Meter side ”+” and "—" terminal as an output, respectively, should be connected to the ”+' and '-” terminal of two
