The Roland KC-110 is a compact, high-efficiency 30 W stereo keyboard amplifier designed for versatile use in various settings, from home practice to outdoor performances. Its primary function is to provide stereo playback for keyboards and other electronic musical instruments, as well as microphones and portable audio players, all within a single, portable unit.
The KC-110 serves as a comprehensive amplification solution for musicians. It features a built-in high-efficiency stereo 30 W power amplifier, delivering 15 W + 15 W when powered by the AC adaptor, or 10 W + 10 W when using alkaline batteries. This power drives two 6.5-inch (16 cm) speakers and two tweeters, ensuring wide-range stereo sound reproduction.
The amplifier offers a dual power design, allowing it to operate using either eight AA batteries or the included AC adaptor. This flexibility makes it suitable for use anywhere, including outdoor performances when paired with a battery-powered musical instrument. It supports rechargeable nickel-metal hydride batteries, offering approximately 8 hours of running time, while alkaline batteries provide about 7 hours.
For connectivity, the KC-110 is equipped with a full complement of input/output jacks. It includes one microphone/instrument input (CH 1), two stereo inputs (CH 2 and CH 3) for keyboards or other electronic musical instruments, and AUX IN jacks for connecting CD or portable audio players. LINE OUT jacks are also provided for connecting to a mixer or recorder. This makes the KC-110 an ideal amp for a keyboardist/singer, or for use as a small mixing monitor or PA system. A convenient headphone jack is included for private practice or sound checks.
The KC-110 also integrates high-quality stereo digital effects, including stereo reverb and stereo chorus. The chorus effect offers a "WIDE" mode, which combines chorused signals in the air to deliver an enveloping sense of spaciousness, leveraging the amplifier's stereo capabilities. A separately sold foot switch can be connected to toggle these effects on and off.
Powering the Unit: The KC-110 can be powered by either the supplied AC adaptor or eight AA batteries (alkaline or nickel-metal hydride). When using the AC adaptor, ensure it is correctly connected to the DC IN jack and the power cord is plugged into an AC outlet. For battery operation, carefully insert the batteries, observing the correct polarity. It's recommended to keep batteries installed even when using the AC adaptor, to ensure uninterrupted performance in case of accidental disconnection.
Turning On/Off: Before powering on, ensure all external equipment is off and all level knobs (CH 1-3, AUX IN, VOLUME) are set to 0. Switch on external equipment connected to CH 1-3 or AUX IN, then power on the KC-110. If using LINE OUT, power up the connected equipment last. To power off, reverse these steps. A brief interval after power-up is normal due to a protection circuit.
Adjusting Volume and Tone: Start by setting the level knob of each channel to 5 (center), lowering unused channels to 0. If using a microphone, turn the CH 1 level knob to the MIC range. Adjust the overall volume using the [VOLUME] knob while producing sound from the connected device. Fine-tune the volume balance of connected devices using individual channel level knobs. The [LOW] and [HIGH] knobs adjust the tonal character of the low and high-frequency ranges, respectively, for the speaker and headphone output. These equalizer knobs do not affect the LINE OUT.
Applying Effects: The [EFFECT] knob allows selection and adjustment of reverb and chorus effects. Turning the knob to the left half engages reverb, while the right half engages chorus. Turning it further right within each range increases the effect depth. The far-right position activates the "WIDE" chorus effect. Note that effects are not applied to sound input from the AUX IN jack. A separately sold foot switch (BOSS FS-5U) can be connected to the FOOT SW jack to control effects remotely.
Connectivity:
Versatile Placement: The KC-110 can be used with a separately sold speaker stand (ST-A95) for simple PA or monitor applications. An "arm stand" is built into the KC-110 itself, allowing it to be placed on the floor at a convenient angle for monitoring. When using the ST-A95, ensure the stand is adjusted to a height of no more than 140 cm and the tripod spread is 98 cm or more for stability. Always place the system on a stable, horizontal surface.
Battery Management: The KC-110 uses eight AA alkaline or nickel-metal hydride batteries. Nickel-metal hydride batteries cannot be recharged by the KC-110 itself; a separate charger is required. The POWER indicator will dim when batteries run low and blink when they are extremely low, signaling the need for replacement. If sound distortion occurs at high volumes due to low batteries, replace them or use the AC adaptor. Remove batteries if the unit will not be used for several months to prevent leakage.
