BUILD A LOW COST AMPLIFIER 30W
is a very affordable stereo amplifier of 15W per channel. This amplifier is ideal for small spaces, has been tested in videorockolas. Their response is flat, you can equalize the sound from the computer software of the videorockola.

This stereo amplifier is ideal for beginners, for its simplicity and low cost. Use the built-TDA2030 is a monolithic integrated circuit class AB. Can provide 15W of output power with a load of 8 ohms.
The TDA2030 provides high output current and very low harmonic distortion. The device also incorporates a short-circuit protection automatically limits power dissipation to keep the working point of the output transistors by ensuring its operation. It also includes a conventional thermal shutdown.
For simplicity, this project can be assembled in a few minutes, providing acceptable performance. If you want to be adding some of the preamps that are in our section projects, and so drive tones.

The design of the power of this amplifier is a voltage doubler and the TDA2030 is powered by dual source, this avoids having to get a transformer with central TAP, and you just need a transformer 12v at 4 amps easy to work perfectly.
This amplifier can be used with speakers of 60W of power on, and an impedance of 8 Ohms. The size in inches, is your taste. We recommend 8 to 10 inches.
The design of this form amplifier brings the volume control built for easy assembly. It also comes with an LED that served as pilot on, and a switch connector should join him in luxury box.
A great advantage of this amplifier is that it brings a built-in voltage doubler. This allows the use of a simple transformer (two wire output), the doubler converts alternating current to direct, as well as its name suggests, doubles.

This user Manizales Colombia, using a 30W amplifier, three input preamps with microphone, line and eq , and a signal summing , joined this small console 3 channels with a channel for high-impedance microphone and 2-channel low impedance microphone.
This is one of many possibilities that can be done with the projects that are in construyasuvideorockola.com . Only just a little imagination, to find many applications and combinations that can be very useful and fun as they learn something that can become a way of living.
is important to consider interconnection of each project, unifying land and maintain a color code to identify the left-right channel and not offset errors. These details are essential to the success of the project.
Some people see the connectors as an unnecessary expense, but really, the use of connectors is very useful when assembling, or do maintenance.
Notice how all the parts are interconnected by connectors.
