Audio Connection Options
When connecting to a home theater receiver, depending on its inputs, you can use the
following DCX3501-M audio outputs:
HDMI
Unlike a DVI connection, an HDMI connection is capable of carrying digital video and audio
signals to the TV or a home theater receiver equipped with HDMI switching support.
The HDMI connection can deliver Dolby Digital Plus, Dolby Digital, Linear PCM, and other
digital audio formats to a compatible TV or home theater receiver.
Digital audio
optical (S/PDIF)
or digital audio
coaxial (S/PDIF)
If the TV or home theater receiver supports it, use either the S/PDIF digital audio optical or
S/PDIF digital audio coaxial outputs to deliver Dolby Digital and Linear PCM audio to a Dolby
Digital home theater receiver.
•
For an HDMI or IEEE-1394 video connection, no additional audio connections to the TV
are required.
•
For RF output, no further audio connection is required
Baseband
Audio L and R
If the audio receiver does not support Dolby Digital, use the baseband AUDIO L and R
outputs to connect to the audio receiver. The DCX3501-M offers two sets of Baseband
Stereo L/R audio outputs. One set provides fixed volume audio while the other set provides
volume-adjustable audio.
If the customer equipment supports it, use either the optical S/PDIF or coaxial S/PDIF
output instead of the AUDIO L and R outputs. The S/PDIF outputs offer better audio
quality, including support for Dolby Digital 5.1 Surround Sound. The HDMI interface
supports Dolby
®
Digital Plus (7.1) audio.
The cabling diagrams show sample audio/video (A/V) connections to an audio receiver,
where the receiver functions as an A/V router. When connecting to an audio receiver,
reference its installation instructions for directions on connecting to baseband and digital
audio (S/PDIF) ports.
Note: The VCR and TV receive their A/V signals from the currently selected input device
on the audio receiver. This is important when the subscriber has another A/V device such
as a DVD player, secondary VCR, CD player, or other electronic component. Motorola
recommends connecting the TV to the monitor output so on-screen menus for the
receiver can be displayed. (Receivers themselves often have interactive on-screen
menus.)
