My Circuit

Actually, 5.1 channel amplifier consists of 6 amplifiers 1 channel mono, which has certain specifications on each canals. Has 6 channel surround sound amplifier that consists of Front Left | Center | Front Right | Rear Left (Left Surround) | Rear Right (Right Surround) | and LFE (Subwoofer). For clarity I give a simple illustration of the layout and the circuit for these speakers. 5.1 Speaker Setup Accoustic Field Generator Acoustic Field Generator is generating acoustic sound with surround effects are adjustable with a standard Dolby Surround, able to produce surround sound is good enough but not too much need of funds. Technological developments as if not only focused on one area alone but on all fronts. The development of technologies that exist today one of them is in the field of audio. With more advanced audio technology today not only as mere entertainment but has become a hobby, hobby is not cheap of course. Many audio enthusiasts trying to make music sound t...

I may have mentioned a while back that a friend of mine generously donated a couple of nut and saddle blanks – one set in Corian and one set in ebony. I already used the Corian nut blank to make a raised nut for playing slide guitar (as seen HERE). Now it was time to put the ebony to use. My acoustic only came with a plastic nut and saddle, so I was keen to see what sort of a difference this would make (to be discussed later). The ebony blanks: The first thing I should mention here is that ebony is a very difficult wood to work with. The only thing I can compare it to is frozen chocolate. It’s extremely hard, but it’s still possible to chip bits off the edge quite easily, so you have to be very careful, patient, and have very sharp tools. First thing to do was to remove the old nut and saddle to use as a template. These were then traced around on the nut and saddle blanks. Let’s look at the process of making the saddle first. The tracing: Cutting to length: Initial, quite rough, shapin...

Ready Bluetooth solutions are often quite expensive. The cheapest Bluetooth modules that are currently commercially available, there are from the Chinese manufacturer Rayson . The modules BTM-112 (Class 2) and BTM-222 (Class 1) each cost around 15 €. Since the modules are designed for 3.3V supply voltage is required for connection to a 5V system in addition to a 3.3V voltage regulator for 2 level converter (Level Shifter) for the UART signals. In addition, you do not want to give up a status display with LED safely. The price of a module is still all in all about 20 €. The circuit The circuit of the Bluetooth module is designed to operate on a 5V system. As a voltage regulator, a controllable LM317L is used.Similarly, a 3.3V voltage regulator such as the LF33CV could be used. Level converter A level converter (English Level Shifter) is used to adjust signal levels of different voltage levels. A typical example of a level converter is for example a RS232 converter. This converts the 1...
