All Audio (Embedded or Audio Only) - Routing to Differing Types of Destination Devices
The Audio Switching Output Board can route the HDMI embedded audio signal from an HDMI Input Board to an audio-
only destination (its breakaway function) while the HDMI embedded audio signal remains intact from the HDMI Output
Board to another destination device or devices (FIG. 77):
IMPORTANT:
When audio is routed as a breakaway signal from an HDMI signal, the audio also remains intact as
embedded audio on the HDMI signal.
Audio Switching Board Numbering Overlays
The Enova DGX 6400 can hold up to four Audio Switching Boards (two in the lower input-side expansion board slots and
two in the upper output-side expansion board slots). The Audio Switching Boards in the top of the enclosure work in
conjunction with the Input Boards; the Audio Switching Boards in the bottom of the enclosure work in conjunction with the
Output Boards. Overlays are provided to simplify Audio Switching Board connector wiring on the Enova DGX 100 Series
enclosures that contain ASB boards (FIG. 78):
Applying ASB Overlays to Numbering Plates
1.
Check the labels on the overlay to determine which system it applies to (see table below).
2.
Peel the backing off the overlay and discard the backing.
3.
Align the overlay carefully on the numbering plate and then press firmly on the overlay to set the adhesive on the
numbering plate.
4.
Repeat Steps 1 through 3 as necessary for any remaining overlays.
