 VU Meter Driver PCB Board Stereo for Two VU Meters

OT820

 

Specifications:

Power voltage: AC 20V to AC 26V(not more than 26V)

Dimension: 52mm x 67mm x 32mm

It can connect two VU meters (100μA to 500μA). You don’t need to adjust for our VU meter 500μA. (Others may be adjusted).

 

Introduction:

1. Input:

Default is LOW-0-LOW, two low level input terminals connected to the CD for audio output , left-ground-right.

If connected to the amplifier's speaker output terminals, need to take in the HIGH-0-HIGH, soldered 1R, 9R with the corresponding decay resistance.

1R = 200ohm, 9R = 1.8K, then attenuation is 20dB. And general amplifier gain is essentially flat.

 

2. Output:

VU Meter side of the two groups of '+' and '-' terminal for the output should be connected to the two levels, respectively, table '+''-' terminals. Level meter can be driven sensitivity.

Recommended: DC 100 microamps to 500 microamps. Can not exceed 1mA.

 

3. Power supply:

Driver board need to adopt separate transformer power supply, or independent of the exchange of

winding! Recommended AC 23V ~ 25V. If the direct use of original .

A system power transformer winding or the original system, the tap to give driver board power supply, can cause damage to the driver IC board!

 

Package included:

1 x VU Meter Driver PCB Board
