Connections Phones/Output Terminal Before connecting phones or other external equipment, be sure to first turn down the volume settings of the keyboard and the connected equipment. You can then adjust volume to the desired level after connections are complete. [Rear Panel] PHONES/OUTPUT Terminal Audio connection 1 3 Keyboard amp, guitar amp,etc. Stereo standard plug White Red PIN plug 2 LEFT RIGHT AUX IN or similar terminal of audio amplifier Connecting Phones (Figure 1) Connecting phones cuts off output from the keyboard's builtin speakers, so you can play even late at night without disturbing anyone. Audio Equipment (Figure 2) Connect the keyboard to a audio equipment using a commercially available connecting cord with a standard plug on one end and two PIN plugs on the other end. Note that the standard plug you connect to the keyboard must be a stereo plug, otherwise you will be able to output only one of stereo channels. In this configuration, you normally set the input selector of the audio equipment to the terminal (usually marked AUX IN or something similar) where the cord from the keyboard is connected. See the user documentation that comes with your audio equipment for full details. Musical Instrument Amplifier (Figure 3) Use a commercially available connecting cord* to connect the keyboard to a musical instrument amplifier. * Be sure to use a connecting cord that has a stereo standard plug on the end you connect to the keyboard, and a connector that provides dual channel (left and right) input to the amplifier to which you are connecting. The wrong type of connector at either end can cause one of the stereo channels to be lost. When connected to a musical instrument amplifier, set the volume of the keyboard to a relatively low level and make output volume adjustments using the amplifier's controls.
