Sustain Pedal

• With piano tones, depressing the pedal causes notes to linger, much

like a piano’s damper pedal.

• With organ tones, depressing the pedal causes notes to continue to

sound until the pedal is released.

Connecting Phones (Figure 1)

Connecting phones cuts off output from the keyboard’s built-in speak- ers, 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 nor- mally 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.

❚ NOTE ❚

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 chan- nel (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 chan- nels 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 ad- justments using the amplifier ’s controls.
