Description VU Meter Driver Board Replaces TA7318P For Power Amplifier Preamp Tube Amp DB Level Meter Driver IC Description: New VU meter driver board replaces TA7318P driver IC. It boasts a better driving effect on your VU meter, the needle of which swings quickly and is responsive. It further increases the output signal on the basis of the TA7318P circuit, which can drive the meters that TA7318P circuit cannot drive before. It adds a wide voltage regulator circuit, the working performance is more stable, the overall layout of the original piece follows the original classic design style, the appearance is beautiful, exquisite and practical! And it can cooperate with the expansion circuit and adds peak indicator! Package Included: – 1 x Set of VU Meter Driver Board Note: – VU meter is not included. Instructions For Use: 1. Signal input: The driver board provides two signal input methods; you can choose one according to your situation! (Reminder: If the signal is taken at the back end of the volume potentiometer or at the output of power amplifier, pointer swing will be controlled by the volume potentiometer. When the volume is high, the pointer swing is large, and when the volume is small, the pointer swing is small.) ①LOW, GND, LOW: are the low-level signal input terminals of the driver board, which are used to connect audio signals of CD players, computer sound cards, front-end devices, and other audio source equipment. When wiring, LOW, GND, and LOW correspond to the left, ground, and right channels respectively. (Adjust the two potentiometers on the driver board to control the amplitude of the needle swing. If the signal is fully turned on, the pointer swing fails to reach your expected value, or the volume becomes smaller, you can remove R2 and R3 resistors on the driver board. R2 and R3 are the attenuation resistors to ground when the driver board is connected to high-level input signals. They are only used when using high-level input. There is no way to determine which signal input method you use, so the resistors are all welded during production. Of course, this is a very special case, and you don’t need to remove them usually!) ② HIGH, GND, HIGH: are the high-level signal input terminals of the driver board, used to connect power signal amplified by power amplifier. The attenuation circuit in the driver board will attenuate the high-intensity level output by the power amplifier and send it to the driver IC. The attenuation circuit includes the R2 and R3 resistors just mentioned. When connecting the output terminals of the power amplifier, the two HIGH terminals of the driver board are respectively connected to the two red binding posts of the power amplifier and the two black binding posts of the power amplifier. Choose any one of them to connect to the GND terminal of the drive board. 2. Drive output: V+, V-, terminal: For backlight of your VU meter. Provide two sets of 12V backlight power supply output terminals. When connecting, please pay attention to match the voltage, positive and negative poles of the light source of your meter. +, -, terminal: Output terminal for driver board driving VU meter, respectively connected to the «+» and «-» terminals of two level meters. Pay attention to the positive and negative poles when connecting. 3. Power supply parameters: – Working voltage AC/DC 12-15V (It is recommended to use an independent power transformer or independent winding for power supply). – Rated power: 3W 4. PCB size: – 60*39mm 5. Accessories: – Connection cable of VU meter is half a meter, divided into two for use.
