By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. * 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. 1. Make sure that all volume controls on the KC-550/KC350 and connected devices are set to 0. 2. Turn on all the devices connected to the KC-550/KC350’ s input jacks (CH 1 through CH 4 and AUX IN). 3. Turn on the KC-550/KC-350. 4. Switch on any equipment connected to the KC-550/KC350’ s LINE OUT or SUBWOOFER OUT jacks. 5. Adjust the volume levels for the devices. * 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. For protection from sudden big sound, 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-550/KC-350 when performing, set the volume as described below. 1. Operate the CH 1 through CH 4 volume knobs to adjust the volume level for CH 1 through CH 4. Adjust the volume balance for CH 1 through CH 4 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, MIDDLE and HIGH knobs to obtain the sound quality you want. 3. Use the VOLUME knob to adjust the overall volume level. * If the sound is distorted, lower the CH 1 through CH 4 volume knobs, VOLUME knob and/or the volume knobs for devices connected to the input jacks (CH 1 through CH 4 and AUX IN). 12 Connect your KC-550/KC-350 Stereo Link Stereo playback is enabled simply by connecting two KC-550 or KC-350 units with a single audio cable (phone type). This function is called “Stereo Link.” As the channel control section is designed to accept stereo signals, connection of sound sources is needed only at the main unit, thus enabling channel volumes to be centrally controlled on the main unit. The right-channel signals are output from the speakers in the main unit, while the left-channel signals are output from the speakers in the sub unit (the other KC-550/KC-350). fig.30-2 Connections When using a Stereo Link configuration, connect all peripheral equipment to the main unit. Do not connect to any input/ output jacks on the sub unit other than STEREO LINK IN . * Before making the connections, be sure that the volume setting of the VOLUME knob for both amplifiers is set to “0.” Switching the power on or off 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. 1. Turn on the devices connected to CH 1 through CH 4 . 2. Turn on the main KC-550/KC-350 amplifier. 3. Turn on the sub KC-550/KC-350 amplifier. 4. Turn on the devices connected to LINE OUT or SUBWOOFER OUT . 5. Adjust the volume levels on all devices. Before switching off the power, lower the volume on each of the devices in your system, then TURN OFF the devices in the reverse order of that used when switching them on. About the Volume and Tone Settings Adjust the Main (R) and Sub (L) volume levels separately using their VOLUME knobs. * You can make each unit's equalizer ( LOW , MIDDLE and HIGH knobs), SHAPE switch, VOLUME knob, and MAIN (R) and SUB (L) settings independently. Basically, they should be set to the same positions, but you can adjust each one as necessary to suit the needs of a particular setup. IN OUT Keyboard Sub (L-channel signals) Main (R-channel signals) Proper Use of the Casters Proper Use of the Casters Attaching and Removing the Casters You can attach or remove the casters as shown in the following figure. Be sure to remove all the casters when accidental movement may be dangerous, such as when setting up the KC-550/ KC-350 on stage, or when transporting it in a vehicle. This is a heavy piece of equipment. To prevent injury caused by the unit overturning or being dropped, two or more people should work together when carrying the unit. If casters have been attached to the amp, make sure it is used only on a stable, level surface. Block Diagram PHONESSPEAKERLINE OUT HPF POWER AMP TWEETER WOOFER LOWMI...
