Before Use
This section explains how to connect to an AC power source, audio and MIDI devices, and a computer
system. Only switch the synthesizer on after you have made all the necessary connections.
It is recommended that you read this section before using the synthesizer.
Power Supply
1Make sure that the instrument’s POWER switch is at the OFF position.
2Connect the supplied power cord to the AC INLET terminal on the instrument’s rear panel.
3Connect the other end of the power cord to an AC outlet. Make sure the synthesizer meets the
voltage requirement for the country or region in which it is being used.
Make sure your S80 is rated for the AC voltage supplied in the area in which it is to be used (as listed on the rear
panel). Connecting the unit to the wrong AC supply can cause serious damage to the internal circuitry and may
even pose a shock hazard!
Use only the AC power cord supplied with the S80. If the supplied cord is lost or damaged and needs to be
replaced, contact your Yamaha dealer. The use of an inappropriate replacement can pose a fire and shock hazard!
The type of AC power cord provided with the S80 may be different depending on the country in which it is
purchased (a third prong may be provided for grounding purposes). Improper connection of the grounding
conductor can create the risk of electrical shock. Do NOT modify the plug provided with the S80. If the plug will
not fit the outlet, have a proper outlet installed by a qualified electrician. Do not use a plug adapter which defeats
the grounding conductor.
