If you build it right and have a big enough power supply you can always just add a second speaker later. The same goes with a very high voltage reading at the output of the amplifier where you should expect a very low voltage reading in the millivolts range.

I would just put a log pot on the inputs. Potentiometer Questions Started by norbss Yesterday at To participate you need to register. It is highly recommended to use a Variac transformer when performing the initial test of the project.

You mean something like these? Factory made is easier and better for getting one of them.

If a Variac transformer is availableconnect the AC input of the power supply to the output of the Variac transformer.

These components are not easy to find. The picture above shows a DC offset voltage for channel 1 at 3. The LM ‘s mute function, when activated, mutes the input drive signal and forces theapplications and performance levels. If you obtain similar DMM readings, you may proceed with music test. Click here to register now. If you going to build your own amplifier do it all at once, Then you have a way to expand your system when you need to.

Contact Us Questions about a project: Use a heat sink for the LM Both genuine devices are available from Fairchild Semiconductor. Can someone supply a schematic, cheers. The LMC is targeted at high volume applications. They will give you far more control and function than you could ever build for datashewt same price. That will give you a good simple volume control.

I dont know what more of a schematic you need other than a dual voltage power supply in the volts per rail at perhaps 15 or more amps capacity. TO; No of Pins: Bear in mind for DJ use, and for a sub in particular, it will be run continually at high sustained powers – it needs to be very well built, and to have massive cooling capability.

The area in the big rectangle is the IC itself. However datsheet test procedures with or without the use of a Variac transformer will be explained. datahseet

PA Amp schematic

It also provides inverse thermal tracking to maintain the bias level as the output stage temperature changes. The LM device is limited to 5mA of output drive current capability.

No abstract text available Text: From the prototype test results, it was determine that this bias voltage is the minimum actual value that produces a well-rounded peak on the output waveform.
