This is a 'line out' output, i.e. low level voltage. This means that you can either connect this output to active loudspeakers (ones with a built-in amplifier, recognizable by the volume control on the loudspeakers themselves) or your Hi-Fi system (the output signal is too weak for normal loudspeakers) or to a sound board, such as SPEA's V7-media fx. This output provides a stereo signal (3.5mm stereo jackplug connection), however a mono jackplug can also be used without danger of short-circuiting the SPEA SHOWTIME PLUS.
