DC 12V Energy Amplifier VU Meter Driver Board DB Audio Stage Meter VU Header Driver Speaker TA7318P DENON
1. Using audio ranges designed for testing the import of built-in circuit chip containing the sq. root dynamic exponential compression circuit (for instance: enter 1V to 1V; enter 4V 2V; enter 9V from 3V) dynamic and precision Reasonable swing pointer directions To keep away from the small pointer signal doesn’t transfer massive pointer signal of the drawbacks.
2. no unbiased energy provide might be straight derived from the unique of in comparison with the TA7318P / TA7332P scale back the price of a transformer whereas occupying the chassis house for half the set up can also be extra handy and versatile. Asylum functions must be examined with out undue delay.
3. Circuit Design has the next traits:Low-pass filter enter circuit put in for top frequency interference filter appropriate for harsh surroundings (similar to automotive audio system);Adjustable output sensitivity for quite a lot of meter head;Probably the most generally used 12VDC energy provide, straightforward to make use of in automotive and PC laptop machine. Reverse polarity safety, relying on energy supply
4. Energy pointer safety to stop pointer primer to increase the lifetime of the primary desk; 0.5W margin steel movie resistors to make sure long-term steady dependable and steady work
5. The technical parameters: [Input sensitivity]: 8025B digital multimeter AC mV audio sign 400Hz enter measurement file enter: 97mV 39 pointer degree meter + 3 dB place.[Power supply voltage]: DC 12V 0.12A! [PCB size]: 5.2×6.3cm; [Power terminal bottom]: DC10~12V 50MA is obtainable For small bulb Energy provide gentle; [Car VU Meter Sensitivity Level]: It is suggested 500UA sensitivity 630 ohms inner resistance.
Right now, the damping impact is the most effective.Different specs of the damping impact meter shall be totally different than tighter.
Word: the ability provide voltage should be strictly assured 12VDC, Though greater than 12VDC may go for a short while however a very long time burn circuit safety, the wiring connection should be carried out.
Directions to be used.
1. Entry in part: Lin 0 Rin is the audio sign enter terminal appropriate for the CD output audio within the left floor channel O related to the entrance enter degree choice terminal terminal shouldn’t be related to the output terminal of brow or output quantity potentiometer
2. the Output part: The 2 “+” and “-” terminals on the VU meter facet are merchandise and must be related to the “+” and “-” terminals of the 2 degree meters, respectively.
Pushed by really useful sensitivity degree meter: DC 100 μA ~ 500 μA. It can’t exceed 1mA!
On board 2 blue 3296 sequence 500 ohm potentiometers can alter the sensitivity of the 2 headings, respectively, Clockwise, the rotation of the sensitivity elevated
LA LB for RA terminals energy backlight. RB for one more group of the backlight energy provide terminals
color: blue + inexperienced + black
Materials: PCB+digital elements
1 x VU Meter Driver Board
(Every batch of digital elements has totally different uncooked supplies,and there could also be variations in product colours and photos)
Solely the above bundle content material, different merchandise will not be included.
Word: Gentle capturing and totally different shows might trigger the colour of the merchandise within the image somewhat totally different from the actual factor. The measurement allowed error is +/- 1-3cm.
