TA7318P pre-Amp PCB driver board VU header Meter db level meter

Feature:
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. )
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.
