NOTE:

 In this example , the S direct plus is converting the unbalanced signal from the DJ mixer to bal-

anced outputs that can be connected to the main PA mixer.

Converting the Output of Unbalanced Devices 

The S direct plus can be quite useful on stage or in the studio for connecting unbalanced 

devices, particularly keyboards and DJ mixers. The output levels of many keyboards and DJ 

mixers are low, so their signals can benefit greatly by connecting their unbalanced outputs to 

the S direct plus. By doing so, the signal can be sent cleanly for long distances while benefit-

ing from the low noise and common mode rejection provided by S direct plusʼs balanced low-

level output.  The diagram following shows a typical hook-up for a DJ mixer connected to a 

stereo stage monitor system and the main PA mixer.
