Setting Up
The EX5 or EX7 can be used virtually on its own — with a pair of headphones or a simple
instrument amplifier — or it can be the core of complex and powerful music production
system. Naturally, the EX5R Tone Generator will require an external MIDI keyboard or other
controller.
Power Supply
Before making any other connections the “female” end of the AC power cord supplied with the EX5,
EX5R, and EX7 should be firmly plugged into the rear-panel AC cord socket. Ideally the power cord
should then be plugged into a convenient AC outlet after you've made all other necessary connections
and placed the EX5, EX5R, or EX7 in the position in which it will be used. Always make sure that the
POWER switch is in the OFF (extended) position before plugging the power cord in an AC outlet.
WARNING!
Make sure your EX5, EX5R, or EX7 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 EX5, EX5R, or EX7. If the supplied cord is lost or damaged
ands 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 EX5, EX5R, or EX7 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 EX5/EX5R/EX7. 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.
