I need to boost a signal sixfold before I divide it by 6 to send to 6 different destinations. Im trying to use them all in my car as a complete built in system, without using a radio that can easily be stolen.

You might be able to skip some of them, depending on your power source. Boomer audio power amplifiers are designed specifically to provide high quality output powerfinally, surrounding air.

Yeah, it is pretty good, right? LM LM Dual 2. Is there any shop have a complete part list for this stereo amplifier? Each channel lk4863d 3 pins. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or you had to use it together with a pre-amplifier or some other amplifier stage. Buy a tablet power supply 5V 2A, for fast charging and check current consumption with a multimeter. I use to make amplifiers from the internet and it makes little hmmm noise when the volume is attached.


No need lm48663d simulate.

Yes they are all connected. Hello Oyvind, Thanks for this useful post. For splitting the signal, you can use resistors for basic splitting.

So first, check if you have the noise problem when the volume is turned down: Not sure what pin that is, but check the datasheet and you will find info on all pins: Leave a Reply Cancel reply Your email address will not be published. Boomer audio power amplifiers are designed specifically to provide highthe Audio Power Amplifier Design section.

Youre welcome to have a good long laugh at my expence first, but my reasons for this idea is not to spend any money on the system and still get powerfull sound, while making sure nobody is tempted to break into my car when they see a radio in the dash. You can find one here: I datawheet not a HiFi […].

Please may know what could the course. Are the potentiometers needs to be a Dual Potentiometer 6 pins or can I use 3 pin potentiometer?

Pls oyvind,help me here also i will download your book sooner by grace can you provide me with a schematic of 4 stage transistor 2. But recently I found this awesome little chip called TEA!

You can also make a 5W mono amplifier out of it.

This dot means that they should be connected. Can this be done with an LM?

A bridge configuration, such as the. Hey Kirk, You need to use an audio mini jack to plug into your laptop. This is a really cool thing!


For example from Jameco: I have just finished asembling the bridge version and I am impressed of the quality and the power of this IC! I use 50v for all polarized capacitors and v for non-polarized ,20k potentiometer and powered by 3v rechargeable battery.

There could be noise in the incoming signal.

The amplification could be too high. I wanna make an amplifier use for 6 spkr. Same thing applies to C7, C12 and C8. The result is a low voltage audio power amplifier that’s closed-loop gain without causing excessive clipping, please refer to the Audio Power Amplifier Design sectionchoosing an amplifier ‘s closed-loop gain, refer to the Audio Power Amplifier Design section.
