Connecting the K2100E0100 Shaker Kit
1. Connect shaker cable to amplifier (see below). Note: Orange and black overdrive wires are not used.
2. Connect the shaker cable and cooling vacuum hose to shaker.
3. Power amplifier and cooling vacuum with included power cables.
4. Connect input signal via the BNC input connector on the back of the amplifier.
5. Ensure Channel 1 and 2 gain controls is set to off (∞) before turning amplifier on. Note: Gain controls are
located on the rear control panel near signal input connector.
6. Turn on master power switch located on the front of the 2100E18 amplifier and activate vacuum cooling.
Adjust gain control on channel 1 as necessary.
2100E18 User Tips
• Clip (red) LED indicator:
o Normal indication: Illuminates whenever the amplifier is driven beyond full power. The resulting
distortion corresponds to the brightness of the LED. Distortion that causes only brief flashing may
not be audible. During muting, the LED fully illuminates. This occurs during normal “On-Off”
muting.
o Abnormal indication: Bright red illumination while the amp is being used indicates either
thermal muting or a shorted output. If the amplifier overheats, the fan will run at full speed, and
operation should resume within one minute. Allow the fan to run, and make sure the amplifier
ventilation is adequate. A shorted or overloaded output circuit will cause excessive Clip flashing
and possible overheating. If distortion is audible without a Clip indication, the problem is either
before or after the amplifier. Check for damaged shakers or overloaded signal source. The
amplifier Gain control should be in the upper half of its range to prevent input overload.
• Signal (green) LED indicator:
o Normal indication: illuminates when the input signal is strong enough to drive the output to -40
dB from rated 8 ohm power. As signal approaches full power, the LED will illuminate
continuously.
o If no indication: check Gain settings and increase gain if necessary. Check input connections and
audio source for signal. If the Clip LED illuminates with little or no Signal indication, check the
output wiring for shorts.
o Abnormal indication: If the Signal LED illuminates with no signal input, there may be system
oscillations or some other malfunction. Disconnect the load and fully reduce the gain. If the
signal LED remains on, the amp may need servicing.
