[SPEAKER] switch
This switch lets you turn off the P-150’s internal speakers. It
does not affect the output from the [OUTPUT] jacks or the
[PHONES] jack.
2
[INPUT] jacks
These jacks let you input line-level signals from another
electronic instrument, such as a rhythm programmer, external
tone generator, or synthesizer, and monitor it through the P-
150’s internal speakers. Use the [L/MONO] jack when
connecting only a single line.
3
[OUTPUT] jacks
These jacks output line-level signals which can be input directly
to an external amplifier, mixer or other audio device. Use the
[L/MONO] jack if your audio equipment has only one input.
4
Pedal jacks
These jacks let you connect up to three foot pedals and use
them as sustain, sostenuto and soft pedals. A single FC4
footswitch is included with your P-150. If you wish to attach
additional foot pedals, be sure to use only Yamaha models FC4
or FC5.
5
[FOOT CONTROLLER] jack
This jack lets you connect a foot controller (Yamaha FC7,
available separately) for use as an auxiliary controller. The [FC]
foot controller can be assigned to control a variety of functions,
including reverb depth or modulation speed, which lets you
change these parameters by foot as you play.
6
[MIDI] terminals
These terminals allow the P-150 to communicate with other MIDI
devices, using standard MIDI cables. To control the P-150 using
a sequencer or another keyboard, connect the MIDI out jack of
the external device to the [MIDI IN] jack of the P-150. To control
another device (such as a synthesizer or tone generator) using
the P-150, connect the [MIDI OUT] jack of the P-150 to the MIDI
in jack of the external device. The [MIDI THRU] jack simply
passes the data received at the P-150’s [MIDI IN] jack through
unaffected, and is used when connecting three or more MIDI
devices in a series.
