[circle 19] is assigned as the default to Disc 2, but both can be reconfigured as optional
inputs to other sources.
20.
Center Speaker Output: Connect these outputs to the ma and – terminals on your
center channel speaker. In conformance with the CEA color-code specification, the green
terminal is the positive (+) terminal that should be connected to the red (+) terminal on
speakers with the older color-coding. Connect the black (–) terminal on the AVR to the black
negative (–) terminal on your speaker. (See section:
Main Room Installation &
Setup/Speaker Connections for more information on speaker polarity.)
21.
Back Surround Speaker Outputs (7.1-Channel Only): Connect these speaker terminals to
the surround back left/surround back right speakers in a 7.1- channel system. In normal
surround system use, the brown and black terminals are the surround back left channel
positive (+) and negative (–) connections and the tan and black terminals are the surround
back right positive (+) and negative (–) terminals.
22.
Side Surround (7.1-Channel) or Surround (5.1-Channel) Speaker Outputs: Connect
these outputs to the ma and – terminals on your surround channel speakers. In
conformance with the CEA color code specification, the blue terminal is the positive (+)
terminal that should be connected to the red (+) terminal on the Surround Left speaker with
older color-coding, while the gray terminal should be connected to the red (+) terminal on the
Surround Right speaker with the older color-coding. Connect the black (–) terminal on the
AVR to the matching black negative (–) terminals for each surround speaker. (See section:
Main Room Installation & Setup/Speaker Connections for more information on speaker
polarity.)
23.
Front Speaker Outputs: Connect these outputs to the ma or – terminals on your left
and right speakers. When making speaker connections, always make certain to maintain
correct polarity by connecting the color-coded (white for front left and red for front right) (+)
terminals on the AVR21EN to the red (+) terminals on the speakers and the black (–)
terminals on the AVR21EN to the black (–) terminals on the speakers. (See section:
Main
Room Installation & Setup/Speaker Connections for more information on speaker
polarity.)
24.
Optical Digital Audio Inputs: Connect the optical digital output from a DVD player, HDTV
receiver, the S/P-DIF output of a compatible computer sound card playing MP3 files or
streams, LD player or CD player to these jacks. The signal may be a Dolby Digital signal, a
DTS signal or a standard PCM digital source.
Optical 2 [circle 24] is assigned as the default
for Disc 3 but can be reconfigured as an optional input to another source.
25.
Optical Digital Audio Output: Connect this jack to the optical digital input connector on a
CD R/RW, MiniDisc or other compatible digital recorder.
26.
Coaxial Digital Audio Output: Connect this jack to the coaxial digital input of a CD-R/RW,
MiniDisc or other compatible digital recorder.
27.
Remote IR Output: This connection permits the IR sensor in the receiver to serve other
remote controlled devices. Connect this jack to the “IR IN” jack on appropriately compatible
IR controlled equipment.
28.
Remote IR Input: If the AVR21EN’s front-panel IR sensor is blocked due to cabinet doors or
other obstructions, an external IR sensor may be used. Connect the output of the sensor to
this jack.
29.
RS232 Port: This jack is currently used for factory testing and software updates only.
