CRYSTAL REFERENCED STEREO CODER
HIGH PERFORMANCE KIT RANGE
Perfect Audio Every Time.....
|
|
With this kit, you can convert your existing mono Veronica transmitter into a high quality FM stereo broadcast transmitter. The coder takes a separate left and right audio signal on two separate cables and combines them together to form just one signal coming out on one cable. This unique signal is called multiplex and can be fed into any mono Veronica transmitter. Any stereo tuner receiving this signal decodes the multiplex back into separate left and right audio signals. Stereo coder and receiver decoder synchronise to each other using a 19KHz pilot tone which is also added to the multiplex signal. Only the most expensive stereo coders will match the spec of this unit due to the pilot tone being crystal generated.
For the first time high quality FM stereo is available to all, at low cost. This kit includes all parts, PCB and phono input and output sockets allowing easy hook up to your audio source and transmitter. No test equipment is required to set this unit up.
