Panel Descriptions
Rear Panel
7 CH1–CH3 input jacks
CH1: BALANCED jack, MIC/LINE jack
CH1 is equipped with a phone-type MIC/LINE jack and a balanced
XLR-type BALANCED jack that is convenient for connecting a mic.
This channel supports levels ranging from mic input level
(-50 dBu) through line input level (-20 dBu) for sources such as a
sound module.
* Pin assignment of CH1 BALANCED jack
CH2, CH3: LINE jacks
Use these for connecting keyboards, sound modules, and other
devices.
They accept line level input (-20 dBu).
8 AUX IN (STEREO, R/L) jacks
Here you can connect an audio player, electronic musical
instrument, or similar audio source, and listen to it while you
perform.
[LEVEL] knob
Adjusts the level of the input from AUX IN jacks.
9 LINE OUT jack
Connect this to your mixer or recorder.
The EQUALIZER knobs and the [MASTER] knob do not affect the
volume or tone of the output from the LINE OUT jack.
10 FOOT SW jack
If a momentary-type footswitch (sold separately: FS-5U) is
connected here, you can use your foot to turn the internal effect
on/off.
FS-5U
11 DC IN jack
Connect the included AC adaptor.
* Use only the AC adaptor that was included with
the unit.
* To prevent the inadvertent disruption of power
to your unit (should the plug be pulled out
accidentally), and to avoid applying undue
stress to the jack, anchor the power cord using
the cord hook, as shown in the illustration.
12 Battery case
Installing batteries
1. Remove the screws from these two
locations.
2. Remove the battery compartment
cover.
3. Insert batteries, taking care to
observe the correct polarity.
* We recommend that you keep batteries
installed in the unit even though you’ll be powering it with the
AC adaptor. That way, you’ll be able to continue a performance
even if the cord of the AC adaptor gets accidentally
disconnected from the unit.
* To prevent malfunction and speaker damage, make sure to
switch off the KC-220’s power before you insert or replace its
batteries, and before connecting it to other devices.
* If you handle batteries improperly, you risk explosion and
fluid leakage. Make sure that you carefully observe all of the
items related to batteries that are listed in “USING THE UNIT
SAFELY” and “IMPORTANT NOTES” (leaflet “USING THE UNIT
SAFELY” and Owner’s manual (p. 7)).
Removing the battery case
Although it is possible to replace the
batteries without removing the battery case,
battery replacement will be easier if you
remove the battery case.
1. Remove the screws from these
two locations.
2. Remove the battery case.
* Take care that no metal object touches the contacts of the
battery case. This can short-circuit the batteries, causing the
case to overheat or burn.
