Important
• 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.
• If your turntable has a grounding wire, secure it to
the ground terminal on this receiver.
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 receiver’s transformer. In this event, change the
installation location, or move the deck farther from
the receiver.
Connecting audio cables
Connect the white plug to the left (L) jack, and the red
plug to the right (R) jack. Be sure to insert the plugs fully
into the jacks.
Connecting speaker cables
1 Twist the cable cores.
2 Loosen the nut on the SPEAKERS
terminal, and insert the speaker cable into
the exposed hole in the terminal shaft.
3 Retighten the terminal nut.
CAUTION
• When using only one set of speaker terminals
(SPEAKERS A or SPEAKERS B), the speaker used
should have a nominal impedance between 4
Ω
and 16 Ω. When using both sets of terminals,
the connected speakers should have nominal
impedance between 8
Ω and 16 Ω. Consult the
instructions accompanying your speakers for
details regarding the impedance value.
• Make sure the positive and negative (+/–) terminals
on the receiver match those on the speakers.
• These speaker terminals carry HAZARDOUS live
voltage . To prevent the risk of electric shock when
connecting or disconnecting the speaker cables,
disconnect the power cord before touching any
uninsulated parts.
• Make sure that all the bare speaker wire is twisted
together and inserted fully into the speaker
terminal. If any of the bare speaker wire touches the
back panel it may cause the power to cut off as a
safety measure.
