NOTE: See the Connections section, on page 10, for detailed information about
making connections.
Main Power switch: This mechanical switch turns the BDS receiver's power supply
on or off. After you have made and verified all connections (see the Connections
section, on page 10), set this switch to the "On" position. During normal use you will
usually leave this switch set to On; it cannot be turned on or off using the remote
control. To conserve energy when you're not going to be using the receiver for an
extended period of time, set this switch to "Off."
Fan vents: These vents are used by the receiver's fan to cool the unit. Maintain a
clearance of at least three inches (75mm) from the nearest surface to avoid overheating
the unit.
IMPORTANT NOTE: Never block the fan vents. Doing so could allow the BDS receiver
to overheat to dangerous levels.
Speaker connectors: Use the speaker wires supplied with the speakers to connect
the satellite and center speakers to the proper terminals.
BDS 575 and BDS 577 receivers (shown) have connections for five speakers: front
left, front right, surround left, surround right and center.
BDS 275 and BDS 277 receivers (not shown) have connections for two speakers:
front left and front right.
See Connections, on page 10, for more information.
Subwoofer Trigger connector: This connector provides 12V DC whenever the receiver
is on. It can be used to turn on and off other devices such as a powered subwoofer.
Remote IR Input connector: When the IR sensor on the front panel is blocked (such as
when the receiver is installed inside a cabinet), connect an optional IR receiver to the
Remote IR Input connector.
Coaxial Digital Input connector: Connect the coaxial digital output of an audio-
only source component here. The signal may be a Dolby
bitstream or a standard PCM digital-audio bitstream.
NOTE: Use only one type of digital connection for each source component.
Subwoofer Output connector: Use a mono RCA audio cable to connect this jack
to a powered subwoofer's line-level input or LFE jack. See Connecting a Powered
Subwoofer, on page 10, for more details about making connections.
Analog Audio Input connectors: Use these connectors to connect to an audio-only
source devices (such as a tape deck). Do not connect a turntable to these connectors
without a phono preamp.
FM Antenna connector: Connect the supplied FM antenna to this terminal.
Optical Digital Input connectors: Connect the optical digital output of an audio-
only source component here. The signal may be a Dolby Digital bitstream, a DTS
bitstream or a standard PCM digital-audio bitstream.
NOTE: Use only one type of digital connection for each source component.
Network connector: Use a Cat. 5 or Cat. 5E cable (not supplied) to connect the BDS
receiver's Network connector to your home network to enjoy streaming content and
content from DLNA
to Your Home Network, on page 12, for more information.
HDMI
TV's HDMI input. Since the HDMI cable transmits both video and audio to the TV,
we recommend that you set the BDS receiver's HDMI audio output to Off in the
receiver's Audio menu to take full advantage of your BDS receiver's superior audio
performance. If your TV is 3D capable you can watch 3D content in 3D either from
the BDS receiver's built-in disc player or from other 3D-capable source devices
connected to the BDS receiver's HDMI Input connectors (see below).
The receiver's HDMI Monitor Out connection also contains an Audio Return Channel
that carries a digital audio signal from your TV or video display back to the receiver.
It allows you to listen to HDMI devices that are connected directly to your TV (such
as an Internet connection) without making an additional connection from the device
to the BDS receiver. NOTE: You must enable your TV's Audio Return channel output.
Consult your TV's instruction manual for information.
HDMI Input connectors: You can connect up to three additional source devices that
have HDMI connectors to the BDS receiver. The HDMI connection transmits digital audio
and video signals between devices, so you do not have to make any additional audio
connections for devices you connect via an HDMI connector. The BDS receiver will pass
3D video signals from 3D capable HDMI source devices to the TV via the HDMI Monitor Out
connector. See Connecting Your HDMI Source Devices, on page 11, for more information.
NOTE: If you have an Apple TV, connect its HDMI output to the BDS receiver's HDMI 3
input. When HDMI 3 is the selected source you can use the BDS remote to control various
Apple TV functions. See Controlling an Apple TV, on page 15 for more information.
Component Video Input connector: If you have a video source device that has a
component video connector (and does not have an HDMI connector), use the component
video connector. You will also need to make an audio connection from the device to one
of the BDS receiver's audio input connectors. See Connections, on page 10, for more
