signal types the PAM1 can automatically configure the audio monitoring characteristic appropriate
to the operation on a preset by preset basis.
PCM Default
can be set to ‘OFF’ or ‘STEREO’ where a detected incoming PCM signal will cause
the PAM to either remain in its current monitoring state (OFF) or default to STEREO
Dolby Default
can be set to ‘OFF’, ‘Lx Rx’ or ‘ALL’ where a detected incoming Dolby signal will
cause the PAM to either remain in its current monitoring state (OFF), to automatically Downmix
the signal (Lx Rx) or send the decoded 5.1 components to the external surround speaker output
AES and analogue connections (ALL) providing they are set to ‘Variable’ mode.
Application Example: When
the ‘Hear Box’ is set to monitor any given pair as part of a preset, the
default monitoring condition for both internal and external speakers is to reproduce the audio in
stereo. If the associated preset is set with a condition where the Dolby Default is set to ALL, the
PAM1 will automatically select the surround 5.1 audio components of an incoming Dolby encoded
signal and route them to the external speaker outputs. This kind of application may be used in an
environment where PCM audio is always associated with stereo signals and Dolby encoding is
used for 5.1 emission.
2.19 Auxiliary Input Mixer
The Auxiliary Input Mixer (AIM) is intended for use in environments where users of PAM1 wear
headphones during normal operation and need to listen to an additional audio input signal such as
Intercom (Talkback) mixed into their monitoring feed.
The
Auxiliary Input Mixer provides the ability to select exclusively from either an Analogue or
AES audio input and to mix that audio signal into the PAM1 monitoring output buss. The resultant
signal can be heard through either headphone or the loudspeaker outputs. The selected auxiliary
input signal can be defined as either mono or stereo in order that an associated input signal (such
as a line level mono output from an
Intercom Panel or Matrix) can be plugged into the left or
right leg of the selected input and heard through the left, right or stereo outputs of the PAM1 .
Auxiliary Input Mixer can be accessed via the Setup 2 menu where 3 buttons allow the user to
select the desired input, define whether it is mono or stereo and adjust an input level trim. In order
that the input level can be quickly adjusted, the level trim control is duplicated on the
Input menu
screen.
Auxiliary Input Mixer
is a global feature whose parameters and settings are not saved as part of
a User Preset .
Aux Source : By using the encoder to select the Aux Source button, the user can scroll through
the inputs and select the required source to route to the Auxiliary Input Mixer . Analogue Stereo
Inputs 1 to 6 and AES pairs 1 to 8 are available for exclusive selection.
