DC 12V Energy Amplifier VU Meter Driver Board DB Audio Degree Meter VU Header Driver Speaker TA7318P for Denon

1. The usage of 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 Average swing pointer directions To keep away from the small pointer signal doesn’t transfer giant pointer signal of the drawbacks.
2. no impartial energy provide might be immediately derived from the unique of in comparison with the TA7318P / TA7332P scale back the price of a transformer whereas occupying the chassis area for half the set up can be extra handy and versatile. Asylum purposes ought to 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 setting (equivalent to automotive audio system);Adjustable output sensitivity for quite a lot of meter head;Essentially the most generally used 12VDC energy provide, straightforward to make use of in automotive and PC pc machine. Reverse polarity safety, relying on energy supply
4. Energy pointer safety to forestall pointer primer to increase the lifetime of the primary desk; 0.5W margin metallic movie resistors to make sure long-term steady dependable and secure work
5. The technical parameters: [Input sensitivity]: 8025B digital multimeter AC mV audio sign 400Hz enter measurement file enter: 97mV 39 pointer stage meter + 3 dB place.[Power supply voltage]: DC 12V 0.12A! [PCB size]: 5.2×6.3cm; [Power terminal bottom]: DC10~12V 50MA is on the market For small bulb Energy provide mild; [Car VU Meter Sensitivity Level]: It’s endorsed 500UA sensitivity 630 ohms inside resistance.

Presently, the damping impact is the perfect.Different specs of the damping impact meter will likely be totally different than tighter.
Word: the facility 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 linked to the entrance enter stage choice terminal terminal shouldn’t be linked to the output terminal of brow or output quantity potentiometer
2. the Output part: The 2 “+” and “-” terminals on the VU meter aspect are merchandise and ought to be linked to the “+” and “-” terminals of the 2 stage meters, respectively.
Pushed by really helpful sensitivity stage meter: DC 100 μA ~ 500 μA. It can’t exceed 1mA!
On board 2 blue 3296 collection 500 ohm potentiometers can regulate the sensitivity of the 2 headings, respectively, Clockwise, the rotation of the sensitivity elevated
LA LB for RA terminals energy backlight. RB for an additional group of the backlight energy provide terminals
