Yamaha NS-45 User Manual

Read these precautions carefully before using your speakers.
● Any time you notice distortion, reduce the volume of your
amplifier. Never allow your amplifier to be driven into "clipping".
Otherwise the speakers may be damaged.
● When using an amplifier with a rated output power higher than
the nominal input power of the speakers, care should be taken
never to exceed the speakers' maximum input.
● Do not attempt to clean the cabinets with chemical solvents as
this might damage the finish. Use a dry, soft cloth.
● To prevent the cabinets from warping or discoloring, do not
place the speakers where it will be exposed to direct sunlight
or excessive humidity.
BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE
AMPLIFIER IS SWITCHED OFF.
CONNECTIONS
● Connect the screw-type input terminals at the rear of the
speakers to the speaker output terminals of your amplifier with
the provided speaker cords.
● One side of the speaker cord is red and the other side is black.
Connect the (+) terminals on both the amplifier and the
speakers using this red side. Connect the (–) terminals on both
components using the black side of the cord.
● Connect one speaker to the left (marked L) terminals of your
amplifier, and another speaker to the right (marked R)
terminals, making sure not to reverse the polarity (+, –). If one
speaker is connected with reversed polarity, the sound will be
unnatural and lack bass.
Procedures:
Loosen the terminal knob.
Insert the bare wire end properly into the terminal hole.
[Remove approx. 10 mm (3/8") insulation from the speaker
cord.]
Tighten the knob.
Test the security of the connection by pulling lightly the cord
at the terminal.
* Banana Plug connections
are also possible. First
tighten the terminal knobs,
and then insert the
Banana Plug connector
into the corresponding
terminal hole.
