-What to Expect-
The quality of the stereo 3D expander is totally dependent on a good stereo signal source; it will NOT
create a stereo image from a mono source. The KP-500SN is ideally placed 3-6 ft. in back of you at
about 2 ft. above the floor. Your position should be at amplifier center for best expander stereo effect.
Experience has shown that placing the amplifier on the floor can provide more bass, but depending on
how close you are to the KP-500SN, you may not hear enough treble. Tilting the KP-500SN back
slightly can help direct more “highs” toward you.
All rooms will sound different; experimenting with amplifier placement can improve the sound for
your audience.
-Control Panel-
The KP-500SN has two input channels and a master control area. Channels one and two are the same.
Inputs: Two sets of unbalanced ¼ stereo pairs. If you have a mono signal and want both channels to
respond, use the right/mono input. All inputs are available simultaneously.
Micophone input: A balanced XLR microphone input (located on rear panel) is assigned to channel
two’s volume and EQ controls. It is a mono input to left and right channels and XLR line outputs. The
XLR input works simultaneously with channel two’s ¼” inputs. The XLR input is AC coupled so
phantom powered microphones can be used. (The KP-500SN does not supply phantom power).
Volume works in conjunction with your signal source volume and volume pedal (if used). Typical
setting is 4-6 and should be adjusted so that your signal source/volume control covers the desired
range.
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 adjust 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.
