The signal source of the drive can be connected to the input of the amplifier or the output of the audio amplifier, without changing the original circuits.
The filter circuit design of the pile rectifier bridge, can be transformer or DC power supply, power supply voltage 12-15V/300mA.
Support two-level meter backlight power supply, change Current limiting can be connected to a different backlight.
Features:
Driver board:
The bridge stack rectifier filter circuit design, can be a transformer or a DC power supply, voltage of Power supply 12-15 V/300 mA. Level changes adjustable.
Vu meter:
Voltage 500MV,
weight: 21 grams, excellent quality, beautiful appearance, stable and reliable performance
DC head resistance: 652
Backlight incandescent bulbs.
Operating voltage: 6 ~ 12V AC or DC
In the backlight brightness to meet the requirements of the conditions, lower voltage operation can significantly extend the service life.
The need to use a current limiting resistor in the 100 to 200 series reduces, reduces the impact on the filament sheath
