1. POWER Switch
This switch turns the power on/off.
2. DC IN Connector
Connect the included AC adaptor here.
Be sure to use only the AC adaptor supplied with the unit.
Also, make sure the line voltage at the installation matches the
input voltage specified on the AC adaptor's body. Other AC
adaptors may use a different polarity, or be designed for a
different voltage, so their use could result in damage,
malfunction, or electric shock.
3. MIDI OUT Connector
This transmits MIDI messages from the MC-307 to
external MIDI devices. In addition, if still at the factory
settings, data arriving at MIDI IN is also transmitted.
4. MIDI IN Connector
This connector receives MIDI messages that are
transmitted from external MIDI devices.
5. PEDAL SW Connector
By connecting an optional pedal switch (such as the DP-
2) to this connector, you can use the pedal to perform
operations on the MC-307.
6. OUTPUT L(MONO)/R Jacks
Provide output of the audio signals. Connect them to
your keyboard amp, audio system, or mixer etc. Use
audio cables (sold separately) to make connections.
