17AC IN Connector

Connect the supplied AC cable here. Never use any AC cable other than the one provided, since doing so may cause malfunction.

18Grounding Terminal

In some cases, depending on the environment in which the unit is installed, the surface of the panel may sometimes feel rough and grainy. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect the ground terminal (see figure) 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)

•Gas pipes (may result in fire or explosion)

•Telephone-line ground or lightning rod (may be dangerous in the event of lightning)

19OUTPUT Jacks

These jacks output audio signals to your audio playback system or amplified speakers.

The output destination setting of a part will determine whether its sound is sent to OUTPUT jacks 1 or 2. Normally, the sound will be sent to the OUTPUT 1 jacks.

The front panel VOLUME knob affects only the OUTPUT 1 jacks.

20DIGITAL OUT Jacks

These jacks can be connected to digital audio devices such as CD players and MD players to transfer digital audio signals.

Use a coaxial cable for COAXIAL, and an optical digital cable for OPTICAL.

*The digital output transmits the OUTPUT 1 signal.

*The signal that is sent from the SD-80's DIGITAL OUT jack may be digitally copied for one or more generations.

21MIDI OUT/THRU Switch

If this is set to [IN1 THRU], the MIDI messages sent to the MIDI IN 1 connector will be retransmitted without change from the MIDI OUT 2 connector.

22MIDI Connectors

These connectors can be connected to other MIDI devices, such as a sequencer, allowing the exchange of MIDI messages ("Controlling the SD-80 via MIDI" (p. 53)).

IN1/IN2: These connectors receive MIDI messages from other devices. The received MIDI messages are sent to the computer (in USB mode) or to the internal sound generator (in MIDI mode).

OUT1/OUT2: These connectors transmit MIDI messages to other devices.

23USB Connector

A USB cable can be used to connect the SD-80 to your computer.
