Motion Sound KP-200S - Manual (Page 3)

Expand control increases the stereo spread. The control is totally dependent on the quality of a stereo
source. Mono=No expand. Too much expand may change the tone of some sounds. Use only enough
for effect and then readjust the channel EQ if needed.
Bass <150 Hz Low frequency boost/cut. If you have a bass player, set this at about 5. Bass uses a lot
of power and can make your sound muddy, adjust carefully to preference. If you use the <100 Hz
subwoofer output, read that section first.
Middle controls frequencies from 150 Hz to 3 kHz. This is the most important frequency range of
most instruments---set at “5” and then vary according to preference.
Treble adjusts sound above 3 kHz. Treble is the highest frequency content of sound and the most
directional part of the spectrum. Set at 5 initially and adjust to preference. The highest frequencies do
not travel very far in air, so don’t fry your ears with searing highs that will never reach an audience.

Volume
Normally set at 5-6. If you are playing quietly and input levels are within the normal range, you can
adjust the master volume for quiet amplifier operations. Higher numbers 5-10 allow maximum
headroom, but produce more pre-amp “hiss”. Higher settings should be used in loud band situations.

The ¼” unbalanced input (on the rear panel) is traditionally used to receive a “cue” from a tape or
sequencer to start a song. This is a mono input and the KP-200S will reproduce the sound from both
channels. The sound will NOT be sent to the XRL line outputs. This input can also be used to
monitor other instruments on stage.
XLR Line Outputs
Left and right channels are output for feed to mixing boards. The level is “hot” microphone,
approximately 2 volts p-p 600 ohms nominal impedance. The XLR line outputs will work very well in
most venues. If there is a very large difference in ground potential between the KP-200S and the
mixing board in use, you may need to use transformer isolation or “ground float” boxes to eliminate
noise. Many older buildings can have ground problems. Check AC outlets to prevent shock and to
ensure proper KP-200S grounding. Volume, expand and EQ affect XLR output signals.
Slave Output
Outputs left and right audio from the master volume control to a SL-200S slave amplifier. The
connector is standard “midi” style for convenience in obtaining cords but does not send midi data.
The cord must use all five conductors. Add as many SL-200S (up to 10) to a KP-200S as you need.
Take just the right amount of power to each venue. Play next to a Guitar stack? No problem!
