Caution
• The SIGNAL GND terminal is provided to reduce
noise when connecting the unit to components
such as an analog turntable.
• The PHONO IN terminals are factory equipped with
short pin plugs. These should not be removed
except when connecting a turntable. Be sure to
save the short pin plugs in a safe place.
• Do not insert the short pin plugs in any connectors
other than the PHONO IN terminals. Connecting
them to any other terminals may cause
malfunctions.
• Do not connect the PHONO IN 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 A-50's PHONO IN terminals are designed to be
used only 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
MASTER VOLUME
the installation location, or move the deck farther
from the amplifier.
