2x P-134 VU Meter Head DB Level Power Amplifier w/ Power Supply w/ Driver Board

Description: 2pcs P-134 Amplifier VU Meter DB Level w/ Backlight + Driver Board VU Meter Parameters:*Size: see the product picture;*Pointer material: Nickel silver strips*Pointer color: Orange*Pointer swing direction: from left to right*Pointer length: from the central axis to the needle end 70±1mm*Pointer width: 0.45 ± 0.05 mm*Meter use direction: vertical*Current sensitivity: 1000uA ±10%*Internal impedance: 100Ω ± 10%*Use / storage temperature limit: -10 ° C to +60 ° C RH 35~85% 1.Test experiment bulb: 4pcs blue LED backlight, parallel to PCB (80mA at 3.0 - 3.2V) backlight voltage can be changed to 12V2.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:1. It is a new upgraded version, replacement of the discontinued TA-7318P IC, works better.2. Increase the output signal to drive more models of the meter. And can be combined with the expansion circuit to increase the peak PEAK indicator function. PCB size: 60*39mmRated power: 3WOperating voltage: AC / DC 12-15V Meter connection cable: half a meter in length, divided into two to use 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. Note: It is recommended to use a separate power transformer or separate windings to power the product! If you need the transformer, please contact us.
