70W Stereo Audio Amplifier

This is a stereo amplifier circuit diagram. The amplifier will produce stereo output channel with the power audio output can reach up to 70W for each channel. The amplifier built based great amplifier chip STA550 from STMicroelectronics. Take a note that this amplifier is a bridge amplifier, the speaker`s terminal should not connected to the groun visit page.

44 Watt Mobile Car Stereo Amplifier

Using a mobile phone while driving is dangerous. It is also against the law. However, you can use your mobile phone as a powerful music player with the help of a stereo power amplifier. This does away with the need of a sophisticated in-dash car music system. Most mobile phones have a music player that offers a number of features including preset/ visit page.

Stereo Digital Camera Power-up Pulse Generator

Powering up my twin digital Sony DSC-V1 cameras at exactly the same time frequently synchronizes the cameras to a remarkable degree, within milliseconds. The cameras are powered up by twinned Sony wired remotes by shorting the ACC port LANC signal conductor with the ACC port ground. With experimentation, I find further that the synchronization can be refined to within microseconds visit page. via next.gr

Multi-channel Audio Codec With Stereo Headphone Amplifier

The LM4610 is a DC controlled Tone (bass/treble), volume and balance circuit for stereo applications in car Radio TV and Audio systems. It also features Nationals 3D-Sound Cir- cuitry which CAN be externally adjusted via a simple RC Net- work. An additional control input allows loudness compensa- tion to be simply effected. Four control inputs pro visit page.

PLL Stereo FM Transmitter

The circuit shown here is of a good Stereo FM transmitter that can transmit high quality signals up to a range of 70 feet. The circuit is based on BH1417 PLL stereo transmitter IC from Rhom semiconductors. The IC has separate audio processing sections for the left and right channels, pre emphasis circuit for improving signal to noise ratio, crystal control circuitry for accurate frequency locking, multiplex circuit for making sum ( left plus right) and difference ( left minus right) {see this article for better understanding Stereo decoder circuit} etc. Another important feature of this IC is that the transmission frequency can be set using a 4 channel DIP switch. The IC can be powered from anything between 4 to 6V DC and has an output power around 20mW. At full output power the circuit consumes only 20mA and has a channel separation...visit page. via next.gr
