manual abstract
Wiring diagrams for these jacks are shown below. Make connections after first checking the wiring diagrams of other equipment you intend to connect. * Howling could be produced depending on the location of microphone relative to speakers. This can be remedied by: 1. Changing the orientation of the microphone. 2. Relocating microphone at a greater distance from the speaker. 3. Lowering volume levels. * When connection cables with resistors are used, the volume level of equipment connected to the inputs (CH 1 through CH 3 and AUXIN) may be low. If this happens, use connection cables that do not contain resistors, such as those from the Roland PCS series. ® 9B © ®:GND (2): HOT (3) (3): COLD 8 Making the Connections Switching the Power On and Off * Once the connections have been completed (p. 8), 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. 1. Make sure that all volume controls on the KC-60 and connected devices are set to 0. 2. Turn on all the devices connected to the KC-60's input jacks (CH 1 through CH 3 and AUX IN). 3. Turn on the KC-60. 4. Switch on any equipment connected to the KC-60's LINE OUT or SUBWOOFER OUT jacks. 5. Adjust the volume levels for the devices. 6. Before switching off the power, lower the volume on each of the devices in your system and then TURN OFF the devices in the reverse order to which they were switched on. * This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally. * Always make sure to have the volume level turned down before switching on power. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction. * If you need to turn off the power completely, first turn off the POWER switch, then unplug the power cord from the power outlet. Refer to "Power Supply (p. 5)." About the Volume-level Settings In order to get optimum sound from the KC-60 when performing, set the volume as described below. 1. Operate the CH 1 through CH 3 volume knobs to adjust the volume level for channels 1 through 3. CH2 Adjust the volume balance for channels 1 through 3 at this time. * To adjust the volume level of equipment connected to the AUX IN jacks, use the controls on such equipment. 2. Adjust the LOW and HIGH knobs to obtain the tone you want. 3. Use the VOLUME knob to adjust the overall volume level. * If the sound is distorted, lower the CH 1 through CH 3 volume knobs, VOLUME knob and/or the volume knobs for devices connected to the input jacks (CH 1 through CH 3 and AUX IN). 9 Using a Speaker Stand By using a speaker stand, you can mount the KC-60 at the optimal height for use as a monitor speaker or simple PA device. I /^WARNING • The KC-60 is designed to be used only with speaker stands whose dimensions meet the specifications described below. Do not use it with a speaker stand that does not meet the following specifications. • When deciding on a stand to use with the KC-60, make sure to pick one that is capable of supporting its weight. • Before use, adjust the speaker stand to a height of 165 cm (65") or less and a leg spread of 120 cm (47-1/4") or more, as shown in the figure below. • Using a speaker stand that does not meet the specifications at left or that is adjusted to a height over 165 cm (65"), or a leg spread of less than 120 cm (47-1/4") may result in damage to equipment or injury due to the stand tipping over. • When using KC-60 with a speaker stand, the speaker stand must be carefully placed so it is level and sure to remain stable. • Cables connected to KC-60 should be given enough slack to prevent accidents that might result from someone tripping over them. • To prevent accidents due to falls, do not place any object on the KC-60 when it's mounted on a speaker stand. • Always have at least one other person assist you when mounting the KC-60 on a speaker stand, or when adjusting the height of the stand while the KC-60 remains mounted on it. 10 Appendices Block Diagram Main Specifications Rated Power Output 40 W Nominal Input Level (1 kHz) Input Channel 1 (MIC/LINE): -50 - -20 dBu Channel 2, 3 (LINE): -20 dBu AUX IN: -10 dBu Nominal Output Level LINE OUT: +4 dBu SUBWOOFER OUT: +4 dBu * 0 dBu = 0.775 Vrms Speakers 25 cm (10 inches) x 1 Tweeter x 1 Controls Channel 1 (MIC/LINE) Volume Knob Channel 2 (LINE) Volume Knob Channel 3 (LINE) Volume Knob Equalizer: LOW Knob, HIGH Knob VOLUME Knob POWER Switch Indicator POWER Connectors Channel 1 Input Jack (XLR type, 1/4" phone type) Channel 2 Input Jack (1/4" phone type) Channel 3 Input Jack (1/4" phone type) AUX IN Jack (RCA phono type) LINE OUT Jack (1/4" phone type) SUBWOOFER OUT Jack (1/4" phone type) PHONES Jack (1/4" TRS phone type, mono signal output...
