Setting Up Accessory Jacks I Using Headphones For private practicing and playing without disturbing others, connect a set of stereo headphones to the rear panel PHONES/OUTPUT jack. Sound from the builtin speaker system is automatically cut off when you insert a headphone plug into this jack. I Connecting a Keyboard Amplifier or Stereo System Though the EZ-150 is equipped with a built-in speaker system, you can also play it through an external amplifier/speaker system. First, make sure the EZ-150 and any external devices are turned off, then connect one end of a stereo audio cable to the LINE IN or AUX IN jack(s) of the other device and the other end to the rear panel PHONES/OUTPUT jack on the EZ-150. I Using a Sustain Footswitch This feature lets you use an optional footswitch (Yamaha FC4 or FC5) to sustain the sound of the keyboard voice. This is used in the same way as a damper pedal on an acoustic piano - press and hold down the footswitch as you play the keyboard to sustain the sound. • To prevent damage to the speakers, set the volume of the external devices at the minimum setting before connecting them. Failure to observe these cautions may result in electric shock or equipment damage. Also, be sure to set the volumes of all devices at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level. • Make sure that the footswitch plug is properly connected to the SUSTAIN jack before turning on the power. • Do not press the footswitch while turning the power on. Doing this changes the recognized polarity of the footswitch, resulting in reversed footswitch operation. I Using the MIDI Terminals The EZ-150 also features MIDI terminals, allowing you to interface the EZ-150 with other MIDI instruments and devices. (For more information, see page 54.) MIDI instrument Music Rest Insert the bottom edge of the included music rest into the slot located at the top rear of the EZ-150 control panel. 11
