HDMI Audio Switch
The rear panel HDMI audio switches mute or unmute the embedded audio on the related
HDMI connector (see
figure 2
,
B
on page 5). The audio switch affects the audio on the
HDMI loop-thru connector. The LED next to the switch lights when HDMI audio is enabled.
•
Hold the HDMI audio switch up until the LED lights (about 1 second) to enable
embedded audio on the associated HDMI connector.
•
Hold the HDMI audio switch down (until the LED turns off (about 1 second) to disable
embedded audio on the associated HDMI connector.
The switch returns to the middle position after it has been released so the device can
continue to be controlled through SIS commands.
EDID
The XTP FT HD 4K can record and save EDID in a user memory location on the transmitter.
EDID can come from the loop-through display on the transmitter. For EDID management,
use the XTP System Configuration Software (see
EDID Minder
on page 26).
NOTE:
In matrix applications, EDID on the transmitter is assigned by the matrix switcher
using the XTP System Configuration Software.
Audio Output Overview
By default, the XTP FT HD 4K prioritizes embedded digital audio over analog audio to send
over the XTP communication. Use SIS commands (see
SIS Configuration and Control
on
page 13) or the XTP System Configuration Software (see
Configuration Software
on page
18) to manually select the audio input.
NOTES:
•
To pass analog audio without video to a display connected to the HDMI output
connector on a connected receiver, the transmitter sends a black video signal to
simulate one of the following video signals:
•
720p @ 50 Hz
•
720p @ 60 Hz (default)
•
1080p @ 60 Hz
•
To set the black video signal, see the
Black video signal
SIS commands on
page 15 or
Transmitter device settings
on page 24.
