Stereo Encoder Multiplexer (Enkoder Stereo)


This stereo encoder is the perfect solution for those looking for a high quality stereo sound transmission at a low cost. This stereo encoder produces an excellent crystal clear stereo sound and very good channel separation that can match with many more expensive stereo encoders that are available on the market. It is all possible thanks to a 38KHz quartz crystal that controls the 19kHz pilot tone, so you will never have to calibrate or re-adjust the circuit.
NJM2035 offers superb quality and is manufactured by NJR CORPORATION (JRC), a subsidiary of New Japan Radio,

NJM2035 offers superb quality and is manufactured by NJR CORPORATION (JRC), a subsidiary of New Japan Radio, a company that is known as the world’s best manufacturer of high end professional audio semiconductors. This transmitter will work with any mono FM transmitter including TX300 and TX500 which are available on our website.
The whole circuit may easily fit on a small 1” x 1.5” printed circuit board allowing to fit in places where space is limited. While building your stereo encoder please take your time and always double check with the schematic to make sure that all the connections are done correctly. If you have any questions, comments or suggestion we will be glad to further assist you
