Connections - Yamaha KMA-700 Owner's Manual

■ Connecting speaker cords
1
Pull the lever up to open, then insert the
conductor wire into the hole.
(+) cord to
(+) terminal
The shaded part ( ) is provided for KMA-700 only.
2
Close the lever to secure the conductor wire.
Before connection, strip a section of coating 15 mm
(9/16") in length from the end of each cord using a
tool such as pliers.
Note
Be careful that the cord conductors projected from a terminal do
not contact with another cord. Contact from the conductors of
different speaker cords may cause damage to the system.

■ Important precautions for speaker
connection
• The maximum outputs of this unit are as follows:
KMA-700 ..................................................120 W + 120 W
KMA-500 ..................................................100 W + 100 W
Accordingly, the maximum input power of the speakers
used must exceed the above.
• Use Yamaha speakers to prevent any trouble or
damage caused by mismatching.
[For KMA-700]
IMPEDANCE SELECTOR
• Before turning on this unit, be sure to set
IMPEDANCE SELECTOR on the rear panel to the
position whose requirements your speaker system
meets.
(Low)
Switch If your system
position uses:
One speaker system
Low
Two speaker systems
One speaker system
High
Two speaker systems
• Do not change IMPEDANCE SELECTOR setting
while the power to this unit is on, otherwise this unit
may be damaged.
Connection examples
The minimum speaker impedance is 4 Ω. If two 6 Ω
speaker systems are connected in parallel, this will exceed
the design value and trigger a safety protector device.
When two speaker systems are used and the protector is
frequently activated, the speaker systems should be
connected serially instead.
