Nikko NA-540 - Speaker Connection

CONNECTIONS AND OPERATION
Do not plug the power cord into an AC outlet until all connections
are completed. Be sure to keep POWER turned OFF.
Speaker Connection and Use
e Connection
Strip off approx. 7mm of the insulation at the end of the speaker cable,
insert it into the hole below (above) the red (black) knob while
pushing on the corresponding knob and, when the cable’s end is fully
inserted, release the knob. Two speaker systems (A and B) may be
connected to this unit. Speaker system selection is done using the
SPEAKERS A and B selector buttons on the front panel.
e Precautions
(1) Be sure you do not short circuit the (+) and (—) terminals of
the speakers.
(2) Connect each speaker making sure the polarity (+ and —) is
correct. :
(3) Do not connect more than one speaker to one terminal.

Turntable Connection and Record Playback
e Connection
Connect the turntable to the PHONO jacks on the back panei using
pin-plug cords. If your turntable is equipped with a ground lead,
connect this to the GND terminal of the unit.
e Record Playback
(1) Press the PHONO selector button and make sure that the TAPE
monitor button is released (OFF position).
(2) Operate the turntable, and slide the VOLUME contro/ to the
desired level.
e Cartridge
Turntables with magnetic cartridges should be connected to the
PHONO jacks on the back of the unit. If your turntable unit features
a ceramic cartridge, it should be connected to the CD/VIDEO jacks.
The PHONO input sensitivity is 2.5 mV with an allowable maximum
input voltage of 140 mV.
e Speaker Cables
To maintain proper damping factor, use the thickest speaker cable
available (AC power cord - 19AWG preferable).
e Speaker tmpedance
Only connect speakers with an impedance of 4 to 16 ohms. However,
when connecting two speaker systems and both systems, A and B,
are used simultaneously, the impedance should be from 8 to 16 ohms.
e Speaker Placement
Normally speakers are placed with their backs against a hard wall,
as such walls reflect low frequencies, thus providing more bass. If
the speakers are facing a hard surface (e.g. a glass surface, a concrete
wall, etc.) these same frequencies will be reflected rather than ab-
sorbed, resulting in deteriorated sound reproduction. Thus, it is re-
commended to arrange a thick curtain, or any other sound absorbing
material, to absorb these frequencies and improve the acoustics in
the listening room.
