Audio Return Program (ARP)
– HDBaseT provides a digital PCM
audio return channel on each output. ELAN’s implementation of this
channel is unique and referred to as Audio Return Program (ARP).
ARP utilizes separate inputs on the HDRE receiver to provide an audio
input that is independent of the monitor. This input may be utilized for
connection to any analog or digital source, and the source connected
may be routed to any analog or digital output.
NOTE:
When ARP is enabled (see HDRE instructions for enable/disable
help) the maximum wire length for the HDBaseT signal is shortened
to 260’ (80m) if using CAT5e. If using CAT6 or CAT7 ARP does not
affect wire length.
Lip Sync Dela
y – Each analog output has up to 170ms of delay that
can be assigned to all sources routed to the output and/or to a specific
source. Where you assign the delay depends on what is causing the
video delay. If only a source is causing the delay, then applying the
lip sync to the source only is appropriate. If the display or a video
processor in-line with the display is causing the issue then delaying
all sources routed to the zone would be appropriate. When a source
with delay is selected in a zone with delay the delays are added and
executed up to a maximum of 170ms.
Lip sync is not available for multi channel digital outputs.
Analog Output Configuration
– Analog zone outputs may be
configured for stereo, dual left channel, dual right channel, dual mono,
and stereo reverse.
Output Grouping
– Zone outputs maybe grouped several ways;
• Sub Zone
– Attaches one analog zone (sub) to another
(master). The subzone tracks the master zone source but
retains independent volume adjustment.
• Zone Grouping
– establishes a set of outputs that can be
easily grouped or un-grouped by the end-user. Outputs for
outdoor areas, entertaining areas, or master suite rooms are
good candidates for zone grouping.
• Whole House Music (WHM)
– Zones are selected
through the g! Configurator for inclusion or exclusion
for WHM. The end user simply selects “Settings” in their
current zone, then presses WHM On and all included zones
are grouped to the active zones source.

System Design and Applications
System Design
The UltraMatrix family of switchers have a vast number of features with
their own potential benefits to the end user. The description of features
and the design requirements of each feature is covered in-depth in the
UltraMatrix Designers Guide. Covered in this manual are just the features
that affect the wiring of an UltraMatrix chassis.
Due to the vast number of possible UltraMatrix connections it is strongly
recommended that you do not attempt to wire the chassis without a
complete one-line document created by the system engineer.
The following examples will provide a connection reference for the many
of the configurations you are likely to see.
HDMI Audio Decoupling
– The sound from HDMI inputs may be used
as a source in audio only zones
HDMI & HDBaseT Mirrored Outputs
– Advanced circuitry allows the
UltraMatrix switchers to output HDMI signals simultaneously on both the
HDMI and HDBaseT connections of each zone.
