Also, all cords and cables should be ‘...........■* placed so they are out of the reach of children. • Never climb on top of, nor place heavy objects on /\\ the unit. • Never handle the power cord or its plug with wet hands when plugging into, or unplugging from, an v-V outlet. Before moving the unit, disconnect the power plug from the outlet, and pull out all cords from external devices. Before cleaning the unit, turn off the power and unplug the power cord from the outlet. Whenever you suspect the possibility of lightning in your area, pull the plug on the power cord out of the outlet. • Before using the unit in a foreign country, consult /jS. with your dealer, or qualified Roland service per- • * sonnel. 3 IMPORTANT NOTES In addition to the items listed under "IMPORTANT SAFETY INSTRUCTIONS" and "USING THE UNIT SAFELY” on pages 2 and 3, please read and observe the following: Power Supply • Do not use this unit on the same power circuit with any device that will generate line noise (such as an electric motor or variable lighting system). • Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/ or damage to speakers or other devices. Placement • Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum. To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference. • Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to temperature extremes. Excessive heat can deform or discolor the unit. • This unit contains powerful magnets. If placed in the vicinity of TVs, it may cause interference (irregularities in color). Should this occur, reposition this unit so it is located at a greater distance from such devices. Maintenance • Caring for the metal parts Wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. • Caring for the covering Clean with a stiff-bristled brush. • Never use benzene, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation. Additional Precautions • Use a reasonable amount of care when using the unit's buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions. • When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable's internal elements. • A small amount of heat will radiate from the unit during normal operation. • To avoid disturbing your neighbors, try to keep the unit's volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you (especially when it is late at night). • When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials. 4 PANEL DESCRIPTIONS CONTROL PANEL CH 1 II CH2 II CH 3 II CH 4 MIC/LINE LINE V LINE ttWIW.k, LOW 5 o—0—^K) 0---10 0 CHANNEL CONTROL 1 Roland 4CH MIXING KEYBOARD AMPLIFIER KC-100 HIGH VOLUME-PHONES POWER MASTER CONTROL ON * OFF 1 JACKS (REAR PANEL) LINE OUT I CH 4 II CH 3 II CH 2 CH 1 1. CHI Controls The unit accommodates a complete range of signals—from mic level (-50 dBm) to line level (-20 dBm). In addition to phone jack, a convenient XLR connector is also provided, allowing for the connection of a microphone. * The pin assignment for the XLR connectors is as shown below. Before making any connections, make sure that this pin assignment is compatible with that of all your other devices. 1: GND 2: HOT 3: COLD 2. CH2 and CH3 Controls The inputs accept line levels (-20 dBm), and feature phone jacks. 3. CH4 Controls CH4 is dedicated to monitoring channel. The inputs accept line levels (-20 dBm), and feature phone jack. The signal that is input to CH4 will not be output from the LINE OUT jack, but will be output only from the internal speaker and from the headphones. This is a very convenient way to provide sound that is meant only for the performer, such as the talkback from the main PA console, or a click track to play to when using sequencer accompaniment, etc. * If your setup does not use line output, CH4 can be used in the same way as the other channels. 4. Master Controls These controls control the output of the built-in speaker and the PHONES jack. LOW: This adjusts the volume of the bass. HIGH: This adjusts the volume of the treble.
