DIGITAL/ANALOG STEREOENCODER
SE3+ is an excellent, low cost, high performance stereo encoder. It was designed to offer great stereo separation and excellent clear sounding audio for the MAX family of FM exciters as well as any other MONO FM transmitter. This encoder will finally provide your FM exciter (MAXPRO 3+ or any other) with quality stereo capability. Digital over-sampled pilot synthesis, audio low pass input filters, selectable pre-emphasis, limiter and basic post mpx filtering ensure excellent distortion-less sound that is sure to please your ear. SE3+ allows excellent compatibility with sub carrier services such as the radio data system – RDS (suitable RDS encoders are also available from PCS Electronics). High quality components and printed circuit board assure24/7 operation for years. Power, optional 19KHz output and audio terminals are all available on the PCB and no soldering is required. SE3+ is available in a KIT form as well and makes for a great weekend fun project. This is a perfect KIT project even for beginners, easy to assemble and setup.
