The Kustom KPM4100 Powered Mixer delivers true versatility, performance, and power- all in a compact and
economical package. It houses its high technology electronics in a rugged steel chassis and is protected by a
vinyl covered wooden cabinet. All of the features you would expect to find in more expensive mixers are
incorporated right here: Balanced microphone inputs with low noise pre-amplifiers, carbon film potentiometers,
tape inputs and outputs, high-quality Digital Effects with an 80 Watt power amplifier.
The typical uses for powered mixers can be strenuous. With setup, tear down, packing and unpacking,
patching and un-patching, it can take its toll on a mixer. Since 1966, Kustom has been building the most
rugged amplifiers in the industry and the KPM4100 has been designed to carry on that tradition. Today, world-
class design means using the most rugged connectors and reliable components and housing them in a rugged
cabinet. Many manufacturers design products for the perfect world rather than the real world. In reality, the real
world has shorted speaker cables, defective speakers, mis-connections, and improper impedances. The
KPM4100 is designed to be tolerant of that imperfect world. With this product, we are able to deliver to you an
amplifier that will ramp up to power within 4 seconds and check itself over to make sure there are no problems
before it allows power to be delivered to the outputs. Also, it will check to see if there are thermal (heat) or
short circuits. If it detects a thermal situation, the unit will shut itself off until the heat dissipates. If it detects a
short circuit, it will continue to pass signal but it will cause the short circuit protection to engage so that the unit
will shut down until the problem is corrected.

INPUT SECTION FEATURES:
3 Pin Low Impedance Microphone Input -
This input is for balanced low-impedance microphones.
Phantom power (15 volts) for condenser microphones is always on and available. It has an input
impedance of 1 K ohm. The connector is wired as: Pin 1 = shield; Pin 2 = positive (hot); Pin 3 = negative
(cold)
1/4" Line High Impedance Input -
This may be used as either a high-impedance microphone input or a line
level device such as tape players, CD players, effects returns or radios. It will also allow connection from
an electric guitar, bass, or keyboard. It is a 2-conductor input with an impedance of 10K ohms. Both the
high and low impedance inputs may be used simultaneously.
Volume Control -
This is the volume control for each channel. It sends the signal to the master mix buss.
Typical operation is between 4 and 8, dependent upon the device(s) on that channel. Please remember
that it acts like a preamp, so if you are using a device that has a volume output control (i.e.: a tape or CD
player) you will need to do some level matching by adjusting the level controls on each unit.
Tone Control -
This is to adjust the overall tone of the individual inputs. It is set at 5Khz. Since it is a cut or
boost control, (+/- 15 dB) it will add or diminish presence frequencies.
Effects Control -
This is a send control to the effects buss. It controls the amount of effects added to the
input signals.
