High Quality Stereo Encoder with NJM2035 This stereo encoder is the perfect solution for those looking for transmitting high quality stereo sound with low cost. This stereo encoder produces crystal clear stereo sound very good and very good channel separation that can match many more expensive stereo encoders that are available in the market. It's all possible thanks to 38KHz quartz crystal that controls the 19kHz pilot tone, so you'll never go back to calibrate or adjust sirkuit.NJM2035 offer superb quality and manufactured by NJR CORPORATION (JRC), a subsidiary of New Japan Radio, a company known as the world's best manufacturers of high end professional audio semiconductors. This transmitter will work with mono FM transmitter including the TX300 and TX500 are available on our website. The entire series can easily fit on a small "x 1.5" printed circuit board that allows to adjust in a place where space is limited. While building your stereo encoder please take y...

Making your own universal remote control systems today is very easy. Such procure the relevant chips, assemble them and here goes, your hi-tech remote control device is working for you. Here we explain a couple RF 433kHz remote control chips especially designed for the purpose. The IC TWS-434 along with its encoder chip HOLTEK’s HT-12E form a high class transmitter circuit, whereas the chip RWS-434 through its complementing decoder IC HT-12D operates as the receiver module. Both of the above modules are able to exchange 4-bits of discrete data for control four external loads separately. With the easy availability of accurate remote control chips, making your own universal remote control modules is today just a matter of few hours. We discuss a couple of compact RF remote control transmitter and receiver modules here using the chips: HT-12E, HT-12D, TWS-434, RWS-434 Making a hi-end professional remote control system at home is a child’s play now. With the advent of micro remote cont...
