Feedback
When using microphones with the SC100, point them away from the speakers to avoid feedback.
This is when the microphone can hear its own output through the speakers and causes a loud howl or
squeal through the speakers. Lowering some of the graphic equalizer sliders can also help to avoid this.
Monitoring
The SC100 has a jack output to enable the main mix to be heard through stereo headphones (30)
The headphones output volume is adjusted using the PHONES rotary control (19). Care should be taken
to keep listening levels within normal limits to avoid hearing damage.
The main mix is also fed as a mono output to the MONO LINE OUT jack (29), which is controlled by the
MASTER L+R faders (20)
Stereo input
Inputs for channel 4/5 are fed in stereo to the L/R main mix. Individual volume levels for the channel
4/5 inputs are governed by the LEFT and RIGHT controls, whereas the overall volume for the stereo
mix is governed by the MASTER control (4).
In some instances, specialist playback material for karaoke or aerobic instruction have a different mix
on the left and right channel. The SC100 has a LEFT/RIGHT SWAP switch to enable the L+R inputs to
be reversed. Channel 4/5 tone controls (13) affect both left and right inputs.
Audio player
The SC100 has an audio player section (1) which can play mp3 files stored on a USB stick or SD card.

Packing away
Before switching the SC100 power off, it is important to set all level controls back to minimum to avoid
any loud pops or clicks through the speakers. Pack all accessories away carefully and avoid trapping
leads or connectors when the lid is closed.
