Setup Procedures:

1. Connect each speaker wire’s “+” and “-” leads to the kickAMP’s Left and Right Speaker Output “+” and “-” termi­nals. Tighten the terminal screws to secure the connections. You may also detach the quick-connectors from the
amplifier assembly to aid installation or to easily move the unit between locations. To avoid damage to speak-

ers, ensure that they are rated to safely handle the amplifier’s 20 Watt per speaker maximum output.

2. Make sure the audio source has a volume control and that the volume is set to a low level. Insert one
end of the Audio Cable’s 3.5mm plug into the kickAMP’s Audio Input connector. Insert the other end of the
Audio Cable into the audio source’s headphone or speaker output.

3. Connect the 24V DC 2A power transformer to the kickAMP’s Power Input connector. Connect the other end of
the power transformer to an AC outlet; you must connect the transformer to the kickAMP before plug-

ging it into the AC outlet.

4. Start the audio source and slowly increase the volume to the desired level.

Frequently Asked Questions

Q- Why aren’t there any volume or other controls on the kickAMP™?

A- Volume, equalization, and left/right balance are centrally controlled by the audio input device.

Therefore, the audio device must have at least a volume control in order to connect it to the kickAMP.

Q- Why does the sound sometimes cut out when I’m playing my music loud?

A- The kickAMP’s automatic protection circuitry is momentarily shutting the unit down. This prevents

damage to the amplifier when the audio source volume is too high or the peak demand exceeds the
amplifier’s capacity. This shut-off is not intended to protect the speakers.

Q- Why don’t my speakers work anymore?

A- First, make sure that the wires are properly connected to both the speakers and the amplifier. Make

sure no strands of speaker wire are shorting + and -. If everything else is good, then you may have
damaged the speakers. To avoid damage to speakers, ensure that they are rated to safely

handle the amplifier’s 20 Watt per speaker maximum output.

Q- Why do I still hear sound or still see the Power LED lit after I unplug power?

A- The amplifier design uses many capacitors, which store extra energy like batteries, to ensure that it

has enough power for the sudden peak demands which are common in music. It takes a few
seconds after unplugging, for all the capacitors to discharge enough to quit driving the speakers
and around a minute before the power is too low for the blue LED. Turn the audio source off before
disconnecting power to avoid hearing music afterwards.

Q- Why is there sometimes a spark when I connect power to the amplifier?

A- The amplifier’s high power requirements increase the potential for sparking/arcing between the

case and the transformer’s connector tip. The amplifier’s case is grounded to reduce the risk of
damage but to avoid this effect, you must connect the power transformer to the amplifier

before plugging it into the AC outlet.

Q- Why do the speaker connectors stick out so far?

A- The connectors are designed to quickly attach and detach speakers to or from the amplifier for

maximum portability. They can be disconnected by pulling them straight out and reconnected by
pushing them in until they click (see Figure 2). Use more connectors (available from NetMedia) to
integrate additional speakers and locations into your kickAMP sound empire.
