*Pointer length: from the central axis to the needle end 44±1mm
*Pointer width: 0.45 ± 0.05 mm
*Meter use direction: vertical
*Current sensitivity: 960uA±8%
*Internal impedance: 650Ω ± 10%

1.Test experiment bulb: Two white LED 2.8-3.0V backlight (can be changed to 12V)
2.Soldering conditions: Place the terminal about 3mm into the tin plate at 230°C for 3.5 seconds. After the test, the 7-14 items remain normal.

3.Soldering temperature: The temperature of the hand-held soldering gun is 350 °C, the terminal is in contact for 3.5 seconds, and the front end of the terminal is about 3 mm in contact with the soldering gun. After the test, the 7-14 items remain normal.

4. Anti-static: Test with the dry nylon cloth on the surface of the transparent cover in the same direction three times. The difference between the markings on the scale is less than 1/3 of the scale length, and the zero return position after three seconds.

Driver Parameters:
Model: TS-VU003
Working voltage: DC/AC 12-18V
Output current: <50mA
PCB Size: 74x50mm
Meter calibration function: support
Backlight power output: 2V-12V 100mA (automatically adjust the output voltage according to the backlight voltage of the VU meter)
Model input: ≤5V rms
Tungsten lamp, LED backlight voltage: automatically adjust the output voltage according to the backlight voltage of the VU meter


1. Power supply: AC/DC 12-16V. To distinguish between AC and DC input terminals.
2. L, G, R: Two-channel input terminals of the driver board, which can be connected to the audio of audio source devices such as mobile phones, computer sound cards, pre-amplifiers (the signal is the signal that can be heard by the earphone), and the attack amplifier output terminal to get the signal. L, G, and R correspond to the left, ground, and right channels of the audio source device respectively, if the input is a mobile phone, computer sound card, preamp, etc. audio source. Please turn the DIP switches 1 and 3 to the "ON" port. If the input is the output terminal of the power amplifier, please turn the DIP switches 2 and 4 to the "ON" port, the signal will be compressed by 11 times. Note: The DIP switch cannot simultaneously switch 1 and 4 to the "ON" port.
3. The adjustable potentiometer "100R-V" is used to adjust the brightness of the backlight of the VU meter.
4. Adjustable potentiometers "50k-1" and "50k-2" control the beating amplitude of the pointers of VU meter 1 and VU meter 2, respectively.

Using:
1. Signal input: There are two signal input methods provided by driver board, depending on your situation,  (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 can be used, because can not 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 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 by by signal 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.

Package: 2x VU Panel Meter Header; 1x Driver Board
