Connect the L and R outputs of the stereo signal from your keyboard to the appropriate jack. If the signal from your keyboard is mono, connect it to L (MONO). Volume is controlled for L and R simultaneously- 4 3. CH4 Controls CH4 is a mono input channel dedicated to monitoring (-20 dBm). The signal that is input to CH4 will not be output from the LINE OUT section, 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 outputs, CH4 can be used in the same way as the other channels. * The PHONES output is mono. 6. Power Switch, Pilot Light This switch turns the power on/off. When the power is on, the pilot light will be lit. * Before turning the power switch on/off, be sure to have all volumes and levels at their lowest value, 0. * 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. 4. Line Out Controls Three independent output jacks (+4 dBm) are provided for line out: MONO, L, and R. These are balanced phone jack outputs. Use the line out level (LEVEL) to control the volume. 7. Stereo Link Jack Connect to this jack when two KC-300 units are used in stereo. * For details on Stereo Link, refer to "Stereo Link" (p. 6). 5. Master Controls These controls control the output of the built-in speaker and the PHONES jack. Two-band tone control with Low and High is provided. The ideally tuned equalization provides a versatile tonal range. The PHONES output provides plenty of power even for high-volume stage situations. When headphones are connected to the PHONES jack, the internal speaker will be silent. * Before connecting or disconnecting headphones, be sure to turn down the VOLUME control for the MASTER CONTROL section to 0. When this unit is operating, the radiation fins located on the rear panel will become hot, so do not touch it with your bare hands.

TIP HOT RING COLD SLEEVE GND 7 To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. On the KC-300, be sure that the volume levels for all Sections are set to ”0." 5 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. Make sure that all volume controls on the KC-300 and connected devices are set to 0. 2. Turn on the keyboard(s) and sequencer (if you're using one). 3. Turn on the KC-300. 4. If a mixer is connected to the LINE OUT jack(s) on the KC-300, turn on the mixer. 5. Adjust the volume levels for the 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. 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 speakers. 3. Lowering volume levels. Stereo Link If two KC-300 units are used, you can easily make connections for stereo output. This function is called "Stereo Link." 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-300). Main (the right-channel signals) Follow the procedure described below to connect two amplifiers with a single audio cable (1/4" phone type). * Before making the connections, be sure that the volume setting of the MASTER CONTROL Section for both KC-300 amplifiers is set to "0."
