NEW VU meter driver board TA7318P Dual channel Stereo module Upgraded version
QTY:1PCS
1. Signal input: drive plate provides two kind of signal input mode, can according to your situation, choose any one! (hint: as in the volume potentiometer back end, or the power output end take signal, pointer swing will be controlled in the volume potentiometer, namely volume big pointer swing, volume little, pointer swing small).
(1) the LOW, GND, LOW: this is to drive plate LOW level signal input terminal, used for barge joint CD machine, computer sound card, former level, such as source of sound equipment audio signal, connection when LOW, GND, LOW corresponding: left, and right sound channel can.
(driver board two potentiometer, can adjust watch hands swing size, such as signal full open, pointer swing is not up to your expectation, but will drive plate on the R2 and R3 resistance take out, R2 and R3, is used to drive plate joint high level input signal to the earth of decay resistance, only in the use of high level input will be used, because can't make sure you specific with what kind of signal input mode, so finished drive plate R2 and R3, are welded, tear down resistance than welding up easy to many, after all, not all people have welding equipment, ha ha, of course it belongs to and special circumstances, usually is not removed.
(2) the HIGH, GND, HIGH: this is the drive plate HIGH level signal input terminal, used for barge joint after borne power amplifier amplification after power signal, drive plate with attenuation circuit, the power output will be HIGH strength level after attenuating into drive IC, attenuation circuit contains just mentioned resistance R2 and R3, connection borne power amplifier output terminal, drive plate two HIGH terminal, respectively joint power amplifier two red terminal, borne power amplifier two black terminal, choose which any one by drive plate GND terminal can.
2. Drive output:
V +, V -, terminal: this is to drive plate for meter backlight, provide two group of 12 V backlight power supply output terminal, connection please note matching meter source voltage and is negative to.
+, -, terminal: this is to drive plate drive meter output terminal, respectively up in two level meter "+" and "-" terminal, connection to pay attention to is negative.
(3) power supply parameters:
Working voltage: AC/DC 12 to 15 v AC/DC wide range working voltage (recommended independent power supply transformer, or independent winding for its power supply!
Rating: 3 w
4. PCB size: 60 * 39 mm
