REAR-PANEL CONNECTIONS
› Pre-Out/Main-In Jumper Pins: These pins con-
nect the receiver's preamp and amplifier sections. Unless
an external amplifier, equalizer or speaker processor is
used, they should be left connected. See page 13 for
more information on external amplifier connections.
fi Preamp Out: These jacks provide an output for
the left and right channels to an optional external
amplifier. In normal operation, unless an external
power amplifier is used, the Jumper Pins › should
remain connected to the Main In Jacks ‹.
fl Subwoofer Out: Connect these jacks to the
line-level inputs of a powered subwoofer. If an external
subwoofer amplifier is used, connect these jacks to
the subwoofer amplifier inputs. When a single, mono
subwoofer is used, or if the subwoofer or its amplifier
has only a single line-level input jack, make the con-
nection to the bottom jack on the HK 3375.
‡ Speaker 1 Terminals: Connect these terminals
to the appropriate terminals on your speakers.
° Speaker 2 Terminals: Connect these terminals
to the appropriate terminals on your speakers.
· Accessory Outlets: These outlets may be used
to power low-current-draw devices such as CD players
or cassette decks. The power to these outlets remains
on as long as the receiver itself is on. When the
receiver is turned off, or placed in the Standby mode,
power to these outlets is removed.
NOTE: The power consumption of the devices plugged
into these outlets should not exceed 100 watts.
a Power Cable: Connect the AC plug to a non-
switched AC wall output.
