Over the years, people have asked for the best way to combine a stereo signal to a mono signal. The best way is to use the S2M by EDCOR. This unit couples a stereo signal to a mono signal and visa-verse. Compared to the typical "Y" connector or resistor circuit the S2M has almost no losses and gives you a perfect signal.
The most common installation of the S2M is coupling a signal from a stereo unit to a mono input of a distribution amplifier. Many office and industrial installations require a 70V or 25V distributed line system to avoid loss of signal. But with several speakers placed in an office you can achieve a pseudo stereo sound by using the S2M with your mono amplifier. Most stereo amplifiers cannot handle an inductive load like that of a distribution transformer and the ones that can, can be very costly.

When using a stereo tape deck, CD player, or tuner for background music, the S2M comes in handy to give you quality sound. You go from the stereo output signal of the tape deck, CD player, or tuner to the mono signal of your power amplifier. It?s USER FRIENDLY!
