High-quality stereo digital effects
Before using this unit, carefully read the sections entitled: "USING THE UNIT SAFELY" and "IMPORTANT NOTES". These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, Owner's manual should be read in its entirety. The manual should be saved and kept on hand as a convenient reference.
The KC-110 can be operated using either an AC adaptor or batteries. Use the type of power that's appropriate for your situation.
* Use only the AC adaptor that is supplied with the KC-110.
Although it is possible to replace the batteries without removing the battery case, battery replacement will be easier if you remove the battery case.
* 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 accidently disconnected from the unit.
* To prevent malfunction and speaker damage, make sure to switch off the KC-110's power before you insert or replace its batteries, and before connecting it to other devices.
* 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.
Batteries that can be used
The KC-110 uses eight AA alkaline or nickel-metal hydride batteries.
* Nickel-metal hydride batteries cannot be recharged by the KC-110 itself. You'll need to use a commercially available battery manufacturer.
* When using nickel-metal hydride batteries, please be aware that the battery life will normally shorten each time they are recharged.
Caution regarding batteries
Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.
NOTE
CHANNEL CONTROL
Level Knobs 1–3
These knobs adjust the volume of the devices connected to the channels.
Turning the knob toward the right will increase the volume.
A microphone can be connected to CH 1.
If you connect a microphone, turn the knob to the range indicated as MIC.
* If you're not using a channel, leave its level knob set to 0.
MASTER CONTROL
[EFFECT] Knob
The position of this knob lets you switch between three effects, and adjust the effect depth.
REVERB:
This effect produces the reverberation of a concert hall.
It is a stereo reverb with a spacious feeling.
The position of the knob adjusts the volume of the reverb. This is also ideal for a microphone connected to CH 1.
CHORUS:
This effect adds depth and spaciousness to the sound.
The position of the knob adjusts the depth of the effect. This is particularly suitable for sounds such as strings.
WIDE:
This is a stereo chorus that processes the three frequency bands independently, creating a spacious, embracing effect.
The low range remains firmly localized in the center, and the sound will become more spacious as you go from the mid to the high range.
* The effect is not applied to the sound that's being input from AUX IN jack.
Equalizer
This adjusts the tone of the speaker output and headphone output.
Normally, you should place these knobs at 0.
* These knobs do not affect the output from LINE OUT jack.
[LOW] Knob
This adjusts the tonal character of the low-frequency range.
[HIGH] Knob
This adjusts the tonal character of the high-frequency range.
VOLUME
[VOLUME] Knob
This adjusts the overall volume that is output by the KC-110's speakers.
If headphones are connected, this adjusts the headphone volume.
* The [VOLUME] knob does not affect the output from LINE OUT.
PHONES
PHONES Jack
You can connect stereo headphones to this jack.
* If headphones are connected, sound will not be output from the speakers.
* You must set the [VOLUME] knob to 0 before connecting headphones.
POWER
[POWER] Switch
This turns the KC-110's power on/off.
POWER Indicator
This will light when the power is on.
* The POWER indicator will become dim when the batteries run low. If the batteries become even lower, the POWER indicator will blink.
Please replace the spent batteries with fresh ones.
CH 1 Input Jacks
Here you can connect up to three devices, such as a keyboard or other electronic musical instrument, a CD player, or a microphone (CH 1 only).
CH 1 BALANCED (XLR) Input Connector
CH 1 Input Jacks
These provide both a 1/4" phone jack and an XLR connector for conveniently connecting a microphone.
This input supports a range from microphone input level (-50 dBu) to the line input level (-20 dBu) typical of a keyboard.
This instrument is equipped with balanced (XLR) type jacks. Wiring diagrams for these jacks are shown below. Make connections after first checking the wiring diagrams of other equipment you intend to connect
* This jack does not supply phantom power.
CH 2, 3 Input Jacks
Here you can connect a keyboard or other electronic musical instrument, or you can connect audio devices such as a CD player (-20 dBu).
If your device uses a monaural output, connect it to L/MONO.
AUX IN Jacks
Here you can connect a device such as a CD or portable audio player (-10 dBu).
Two types of jacks are provided (RCA phono jacks and a stereo mini jack), and the signals are mixed internally.
You may use the two types of jacks simultaneously, but this may cause the volume to be lower than if they are used separately.
* The effect is not applied to the sound that's input from AUX IN jack.
AUX IN [LEVEL] Knob
This adjusts the level of the input from AUX IN jack.
LINE OUT Jacks
You can connect these jacks to your mixer or recorder.
Use L/MONO jack if you're outputting in mono.
The equalizer knobs and [VOLUME] knob do not affect LINE OUT.
FOOT SW Jack
If you connect a foot switch here, you'll be able to turn the internal effect on/off with your foot. You'll need a separately sold momentary type foot switch (BOSS FS-5U; sold separately) and a connection cable.
Set the polarity switch toward the jack.
DC IN Jack
Connect the included AC adaptor here.
You must use only the AC adaptor that is supplied with the KC-110.

* When connection cables with resistors are used, the volume level of equipment connected to the inputs (CH 1–CH 3, AUX IN) may be low. If this happens, use connection cables that do not contain resistors.
You can connect your keyboard in stereo, and sing/narrate while you perform.
Multiple instruments such as keyboard or electronic drums (up to four) can be connected to the KC-110 and mixed.
By using the KC-110 with the ST-A95 speaker stand (sold separately), it can be positioned at the ideal height for monitoring or use as a simple PA system.
* You must obtain the assistance of at least one other person when attaching the KC-110 to the speaker stand, or when adjusting the height of the speaker stand with the KC-110 attached.
* When setting up, take care not to pinch your fingers.
When using the KC-110 at a low position such as on the floor, extending the arm stand will make the sound from the speakers easier to hear.
