CONNECTIONS
Audio 5 In/Out Connections (Option)
Diagram 16 shows the connection options for an audio record/playback device connected to the M80 Audio 5 IN/OUT Connec-
tions. Not all of the connections shown are required for a given setup, but are shown here for reference.
Note: All connections in this section with the exception of analog line level audio require configuration in Source Setup to be-
come active.
Analog Line Level Audio - Though not shown in Diagram 16 , the analog line level audio connections are recommended
and are required for record/playback of analog audio content or if the digital audio connections are not going to be used.
Copyright protection can prevent some digital audio content from being recorded digitally and the M80 does not down-con-
vert digital audio to analog. The analog line level audio connections can be used as backup in most cases to record/playback
analog audio, by selecting the Analog Audio Input, by source, in the Source Setup. The analog line level audio IN connection
is also required to playback audio content from the Audio Recorder to the Zone 2 Speakers, Zone 2 OUT or Zone 2 PRE-OUT, if
used.
1. Follow Steps 1-2 in section: Audio 5 In/Out Connections (Default) .
Digital Audio (Digital Audio Recorder, Music Server, CD Player) - Use either the coaxial or optical digital audio connections
for a given source, do not use both. The digital IN/OUTs typically allow record/playback of digital audio content. Copyright
protection can prevent some digital audio content from being recorded digitally, so having the analog line level audio con-
nections in place for backup is recommended to record the audio content as analog audio. The M80 does not down-convert
digital audio to analog. The analog line level audio IN connection is also required to playback audio content from the Audio
Recorder to the Zone 2 Speakers, Zone 2 OUT or Zone 2 PRE-OUT, if used.
1. Using either a digital coaxial or optical audio cable, connect the appropriate digital audio OUT of the Audio Recorder to
any unused digital coaxial or optical IN on the M80. (Either coaxial or optical input can be used. Be sure to configure the
digital audio input used in Source Setup.)
Note: If the device is an audio/video playback only device, use any compatible, unused video input. (See section: Audio/
Video 1, 2 & 3 Connections for additional information.) Be sure to select the appropriate video input in Source Setup.
2. Using the same type of connection (digital coaxial or optical) as used in Step 1 , connect an unused coaxial or digital
Audio OUT on the M80 to an appropriate digital coaxial or optical audio IN on the Audio Recorder. (Not required for a
playback only device.)
Note: A Coaxial IN can output to either the Coaxial or Optical OUT and an Optical IN can output to either the Optical or
Coaxial OUT. Using the same type of connection (coaxial/optical) for both IN and OUT is recommended.
DVD-Audio/SA-CD: For DVD-Audio HDMI v1.0 or SA-CD HDMI up to v1.1, a separate multichannel analog audio connection
from the device to the M80 Multi Input is required to properly reproduce the DVD-Audio or SA-CD content played on that
device. A DVD-Audio Player with HDMI v1.1 or better or a SA-CD Player with HDMI v1.2 or better will output uncompressed,
multichannel audio via HDMI and can be connected to a HDMI Input on the M80. The M80 will not output this content as
either digital or analog audio and therefore cannot be recorded. The Multi Input on the M80 can also be used for analog
multi-channel audio for a player that has a proper HDMI rev but there are no HDMI Inputs available on the M80. DVD-Audio
and SA-CD multichannel audio are not available on the optical and coaxial connections. Some DVD-Audio and SA-CD mul-
tichannel audio content (when appropriately encrypted) gets down-converted to 2-channels at a lower sampling rate when
output via the coaxial and optical connections. Some of this content will be copy protected and cannot be recorded via the
digital audio connections.
Note: The firmware for many digital audio/video devices can be updated via PC, Internet or Jump Drive download. Check the
audio/video device manufacturers’ web sites periodically for updates, to assure all devices are functioning at their full capabili-
ties.
