Nº40 Media Console Menu System
• NTSC video is used for audio/video zones (either record or
remote) that will be used with NTSC video signals. This setting
establishes the format of the independently-generated on
screen display used for this particular zone.
• PAL video is used for audio/video zones (either record or
remote) that will be used with PAL video signals. This setting
establishes the format of the independently-generated on
screen display used for this particular zone.
• Audio only is used for zones that do not include any video, and
disengages the video portion of the RZone, since it serves no
purpose in an audio-only zone.
Audio output
This RZone option determines the nature of the audio outputs asso-
ciated with this RZone, which depends on how you plan to use it.
Variable provides volume-controlled outputs (both analog and
PCM digital) that is most appropriate for remote zone applications.
It can be controlled via the zone IR input, or by RS-232 commands
issued to that RZone.
Fixed provides a line-level analog signal and a digital signal that is
generally appropriate for record zone applications. In this setting,
you cannot control the volume of the analog and digital outputs.
This ensures that you do not inadvertently ruin recordings by acci-
dentally changing the volume.
Digital output
This RZone option determines whether the digital output is down-
mixed or native.
Downmix converts multichannel signals to two-channel (PCM)
digital signals on the fly, for compatibility with either a digital
recording device or for digital transmission to a remote zone that
can only handle two channel (PCM) signals. This option can also be
volume-controlled (in the digital domain), according to the volume
control setting above.
Native digital passes along the incoming signal (whatever has been
selected for that RZone) in its native format, whether Dolby Digital,
DTS, or PCM. (Incoming analog signals will be converted to 24 bit,
48 kHz PCM and passed along in that form.) This option is most
likely be used to pass signals from the main theater system to a
secondary multichannel theater system elsewhere in the home. It
cannot be volume controlled, as it passes the original signal
through unchanged.
