2.11 Monitoring using external loudspeakers
The PAM1 features an intelligent monitoring matrix designed to optimise the use of both internal
and external loudspeaker systems. Connection of either Stereo or 5.1 loudspeaker systems is
accommodated and monitoring modes automatically configured to ensure that only the audio
components selected are those that are heard using the appropriate output channels.
For example : when listening to a stereo Downmix through a 5.1 surround sound loudspeaker
system, only the left and right speakers are active whilst the centre, LFE and surround speakers
are muted. Dedicated multichannel monitoring modes
ALL and DRC route surround audio
components to 5.1 loudspeakers in the correct channel order without the need for complex routing
configuration.
The table shown in
Section 2.12 explains the default monitoring modes based on the various
menus and DIP switch selections detailed in the following descriptions.
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 front panel volume control).
Stereo or 5.1 external loudspeakers can be connected (see the application diagram in front of this
Handbook).
2.11.1
Discrete PCM 5.1
– Using ALL Mode
The Shortcut and Monitoring menus include an ALL option. By selecting ALL the operator can
select any group of 6 audios channels from the bargraph display corresponding to the 5.1 audio
signals. Once a 5.1 group has been defined, the 5.1 audio stems are routed to the external
speaker outputs in the correct
SMPTE order (L, R, C, LFE, Ls, and Rs).
By repeatedly selecting the
ALL button, the group of selected audio pairs move from left to right
across the bargraph display enabling the user to route discrete 5.1 or 5.0 audio from any location
within the 16 channels displayed to the external variable audio connectors in order to feed
external active 5.1 speaker systems. Pressing and rotating the
ALL button also enables the user
to scroll through the
pair’s selection in the sequence
123, 234, 345, 456, 567 and 678.
The image below shows the ALL button selected from within the Shortcut Menu and the
selection of audio pairs 2,3 and 4 defined as an embedded 5.1 audio programme.
This function ensures that an embedded discrete
5.1 signal can be monitored regardless of the
location of the 5.1 stems. The user can store different settings for monitoring discrete 5.1 audio
using the
Hotkey or User Presets.
