Suggested Performance Application
The following illustration shows the basic interconnections between an SD8 and external equipment when used in a
typical live performance application:
The main connections here involve connecting the SD8 speaker outputs to PA speakers and the Monitor output to the
input of an external amplifier driving onstage monitors. Various microphones and line level signals are connected to
channel mic and line inputs and a CD or tape player is connected to the CD/Tape input. An external signal processor is
connected to Aux Send 2, with the resulting processed signal returned to Aux Returns 1 and 2.
