10 REAR PANEL CONNECTIONS

B Video Monitor Outputs: Connect these
jacks to the composite and/or S-Video input of a
TV monitor or video projector to view the output
of any video source selected by the receiver’s
video switcher.

C Front/Center Speaker Outputs: Connect
these outputs to the matching + or – terminals
on your front/center speakers. When making
speaker connections, always make certain to
maintain correct polarity by connecting the red
(+) terminals on the AVR 2550 to the red (+)
terminals on the speaker and the black (–) ter-
minals on the AVR 2550 to the black (–) termi-
nals on the speakers. (See page 14 for more
information on speaker polarity.)

D Surround Speaker Outputs: Connect
these outputs to the matching + or – terminals
on your left and right surround speakers. When
making speaker connections always make cer-
tain to maintain correct polarity by connecting
the red (+) terminals on the AVR 2550 to the
red (+) terminals on the speakers and the black
(–) terminals on the AVR 2550 to the black (–)
terminals on the speakers. See page 14 for more
information on speaker polarity.

E Switched AC Accessory Outlet: This out-
let may be used to power any device that you
wish to have turn on when the unit is turned on
with the System Power Control switch 2.

F Unswitched AC Accessory Outlet: This
outlet may be used to power any AC device. The
power will remain on at this outlet regardless of
whether the AVR 2550 is on or off (in Standby),
provided that the Main Power switch 1 is on.

Note: The total power consumption of all
devices connected to the accessory outlets
should not exceed 100 watts from the
Unswitched Outlet

F and 50 W from the

E.

G AC Power Cord: Connect the AC plug to an
unswitched AC wall output.

H DVD Video Inputs: Connect these jacks to
the composite or S-Video output jacks on a DVD
player or other video source.

I Video 1 Video Outputs: Connect these
jacks to the RECORD/INPUT composite or 
S-Video jack on a VCR.

J Video 2 Audio Inputs: Connect these jacks
to the PLAY/OUT audio jacks on a VCR or other
video source.

K Video 2 Video Inputs: Connect these jacks
to the PLAY/OUT composite or S-Video jacks on
a second VCR or other video source.

L Optical Digital Inputs: Connect the optical
digital output from a DVD player, HDTV receiver,
LD player, MD player or CD player to these jacks.
The signal may be either a Dolby Digital signal, a
DTS signal or a standard PCM digital source.

M Video 1 Video Inputs: Connect these jacks
to the PLAY/OUT composite or S-Video jacks on
a VCR or other video source.

Note: Either the Video or S-Video output of any
S-Video source must be connected to the 
AVR 2550, not both in parallel, otherwise the
video may be disturbed or its performance be
adversely effected.
