Using headphones allows private practice. Plugging in a pair of headphones turns off the
speakers. You can also insert a "dummy" stereo headphone adapter. This is useful if you want to
mute the internal speaker system while using a more powerful external amplification system
connected to the Audio Out Jack. There are two identical headphone jacks on the Mark Pro 3i.
The USB port allows you to connect the Mark Pro 3i to computer for using MIDI.
MIDI cables provide the connection between the MIDI ports of one piece of equipment and
those of another. To keep things simple, there are only two valid MIDI connections: Out to In, In
to Out.
The audio input jack allows you to play a tape or CD player, or to have an external MIDI tone
module connected to the Mark Pro 3i audio system. The Mark Pro 3i's volume and tone controls
affect the signal coming from the audio in jack, but the reverb and effects settings do not.
The audio output jack is used to boost the sound level coming from the piano by connecting it
to external amplifier and speaker systems. It can also be connected to an audio recorder to
preserve your performance.
