1.USB connector

This connector lets you use a USB cable to connect your computer to the RD-300SX (p. 50).

2.PEDAL jacks (DAMPER, CONTROL)

Connecting the pedal switch (DP series) provided with the RD- 300SX to the DAMPER jack allows you to use the switch as a damper pedal.

With an optional expression pedal (such as the EV series or other model) connected to the CONTROL jack, you can then assign a variety of functions to the pedal (p. 39, p. 40).

3.MIDI connectors (IN, OUT)

Used for connecting external MIDI devices and for transmission of MIDI messages (p. 12, p. 47).

4.OUTPUT L(MONO)/R jacks

Provide output of the audio signals. These are connected to an amp or other device. For monaural output use the L/MONO jack (p. 12).

5.PHONES jack

A set of headphones can be connected to this jack (p. 12). Even when headphones are connected, sound will still be output from the output jacks.

6.Ground terminal

927Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or perceive that the surface feels gritty to the touch when you touch this device, microphones connected to it, or the metal portions of other objects, such as guitars. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect the ground terminal (p. 11) with an external ground. When the unit is grounded, a slight hum may occur, depending on the particulars of your installation. If you are unsure of the connection method, contact the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page.

Unsuitable places for connection

•Water pipes (may result in shock or electrocution)
