Troubleshooting
Audio signal(s) do not route as
expected.
Parameter control not available
as expected.
• Audio Input Controls AES
Passthrough or Zero Delay
Embedding mode may
inadvertently be enabled
• When either of these modes is enabled, flexible
routing and parametric controls are not available.
When either of these modes is not intended for
use, make sure they are disabled.
Refer to Audio Input Controls function
submenu tab on page 3-11 for more information.
Note: Routing and parametric controls may
appear functional when either of these
mode are enabled, although the controls
will not be functional.
• (9035 only) Embedded or
AES audio contains Dolby
®
E or Dolby Digital encoded
signal
• When a valid Dolby
®
E or Dolby Digital™ signal
(in accordance with SMPTE 337M) is detected
on an AES or embedded audio signal, SRC is
automatically bypassed (disabled) along with
gain and polarity controls being bypassed (even
though controls may appear to be functional).
Gain and polarity controls are not available for
this signal type.
Refer to Status Displays in Audio Input
Controls function submenu tab on page 3-11 for

• If any of AES IN 1 thru AES IN 4 are to be used
as inputs, the respective DIP switch must be set
to the default INPUT mode position.
See Setting I/O Switches for AES I/O (1-4) Ports
(p. 2-1) in Chapter 2,“ Installation and Setup” for
more information.
• Dolby-encoded pair not
recognized by downstream
devices/systems
• If framesync is enabled and using Input Video as
source, Audio SRC must be set to Off to
maintain integrity of Dolby pair for downstream
devices.
