PAM1-3G8 Version 7
2.4.3 Dolby E or Dolby Digital Monitoring
When a Dolby E or Dolby Digital encoded audio pair is selected, PAM1-3G8 will
automatically decode the signal into its component parts and name the stems according to
the Channel Coding information carried within the
Metadata . The Monitor Menu screen
changes dynamically to reflect the selection of a Dolby encoded source and the Monitor
buttons now include options pertinent to the Dolby signal (see below).
A Dolby Lt/Rt (or Lo/Ro if selected via the rear panel DIP switch) option appears and
when selected, a Dolby Downmix is derived by PAM1-3G8 and routed to the
loudspeakers. The Lt/Rt (or Lo/Ro ) level is displayed on the 4
th
bargraph pair (see below).
Dolby monitoring modes allow the user to select to hear individual audio
pairs and stems. The example in the screenshot below shows how to „solo‟ the
Centre
Channel and listen to it through the internal or external loudspeakers.
Monitoring using external loudspeakers
De-embedded or decoded multichannel audio (Dolby or discrete PCM) is automatically
routed to the AES and analogue outputs connectors. The rear panel located
DIP Switch
includes a selection to mute internal loudspeakers and to set AES and analogue outputs
to variable level (adjusted by the volume control).
Stereo or 5.1 external loudspeakers can be connected (see the application diagram
below).
Dolby E and Dolby Digital
The Dolby monitoring menu includes options called ALL and DRC. When used with a 5.1
loudspeaker monitoring system ALL routes the decoded 5.1 audio to the multichannel
outputs. In DRC mode, the Dolby decoded 5.1 output is affected by Dolby DRC metadata
and adjusted accordingly. If the monitoring mode is switched away from ALL or DRC then
the Centre , Lfe , Ls and Rs speaker channels are muted and only the Left and Right
channels are active. The 5.1
monitoring selections enable a user to „solo‟ individual
surround sound signals to check the integrity of the audio mix.
