Caution
• The SIGNAL GND terminal is provided to reduce
noise when connecting the unit to components
such as an analog turntable.
• Do not connect the PHONO (MM) terminals to any
component other than a turntable; also, do not
connect to a turntable equipped with built-in
equalizer. An excessively high sound output may be
produced, resulting in damage to your speakers or
other devices.
• The unit's PHONO (MM) terminals are designed to
be used with turntables equipped with MM
(moving-magnet) type cartridges. Turntables
equipped with MC (moving-coil) cartridges cannot
be used.
• Make sure not to bend the cables over the top of
this unit (as shown in the illustration). If this
happens, the magnetic field produced by the
transformers in this unit may cause a humming
noise from the speakers.
• The unit's POWER AMP DIRECT terminals should
never be connected to any other component's
connectors except PRE-AMP OUT.
• If your turntable has a grounding wire, secure it to
the ground terminal on this amplifier.
Note
• When connecting a tape cassette deck, playback
noise may be heard, depending on the installation
location. This noise is caused by leakage flux from
the amplifier's transformer. In this event, change
the installation location, or move the deck farther
from the amplifier.
• iPod is a trademark of Apple Inc., registered in the
U.S. and other countries.
About "Bi-wiring"
This unit can be used with speakers that support bi-
wiring. Be sure to connect the high-frequency and
low-frequency connections correctly.
• During playback, be sure that both the SPEAKERS
A button and SPEAKERS B button are set to ON
(page 7).

Caution
• When using bi-wiring to connect speakers, avoid
adverse affects on the amplifier by being sure to
remove the HIGH and LOW short bars provided
with the speakers. For detailed information, consult
the instructions provided with the speakers.
• When using speakers with removable network
circuits, note that if the network is removed, no
effect will be produced and damage may be caused
to the speaker.
• Another method of connection is to connect the
SPEAKERS A terminals to HIGH and the
SPEAKERS B terminals to LOW (reverse that shown
in the illustration).
