Product Description
Original TA-7318P driver circuit is an upgraded version of the new drive head of the table better,hands swinging rapidly, responsive, and the basis of progress in the 7318 circuit Step increases the drive signal can drive the header of the past, the 7318 circuit can not drive, an upgraded version has been increased to a wide range of regulator circuit, the performance is more stable, The original overall layout follows the original classic design style, beautiful appearance, compact and practical!

1. A signal input: There are two signal input methods provided by driver board, depending on your situation, choosing one of them! (Hint: If the volume potentiometer Side to take the back-end, or the amplifier output signal pointer swing is controlled by the volume potentiometer, that is the volume pointer swing and the volume small pointer swing. )

(1) LOW, GND, LOW: this is driven plate LOW level signals input terminals, used to refute meet CD machine, computer sound card, the former stage, such as audio source equipment audio signal, wiring LOW, when GND, LOW corresponding: left, and right sound channel can be.
(driving plate on the two potentiometer, whose hands can adjust the swing size, such as signal full swing open, pointer is not up to your expectations, but will drive on the board, R3 resistance take out, R2 R2, R3, is used to drive the board meet high level when the input signal to the earth of resistance in use, only attenuation high-level input will be used, because can't make sure you specific use which kinds of signal input methods, so the R2, finished product drive board is welded, R3 resistance welding, tear down than up easily more, after all, is not all people have welding equipment, ha ha, which, of course, belong to and special circumstances, usually is not removed!)
(2) HIGH, GND, HIGH: this is the driver board HIGH level signal input terminals, used to pick up after borne power amplifier amplification by power signal, driven plate with attenuation circuit, will the power output of the HIGH strength level to drive after attenuation IC, attenuation circuit contains just mentioned and R3 resistance R2, connection borne power amplifier output terminals, drive the board two HIGH terminal, by two of the power amplifier were red terminals, the two black borne power amplifier terminals, choose which any one by driving the GND terminal board can.

2. The driver output: V +, V-terminal: this is driven plate for the multiplier backlighting, with the two groups of 12 V power supply output terminals backlighting, pay attention to the connection of the light source voltage and matching headers are aligned to.
+,-terminal: this is to drive the multiplier output terminal board drive, respectively, then in two level table "+" and "" terminal, the connection to the attention of anode.

3. The power supply parameters: Working voltage: AC/DC 12-15 V AC/DC amphibious wide working voltage range (recommended independent power transformer, or independent power supply, such as for its winding with the original audio system share power transformer, may cause driven plate IC damage or audio system fault!)
The power rating: 3W
4. PCB size: 60 * 39mm
5. Accessories: connecting headers to half a metre, in two use.

Package:
1pc TA7318P pre-Amp PCB driver board VU header Meter db level meter
