down-mix Audio Input
In sound recording and reproduction, down-mixing is the process by which multiple recorded paths are combined into
one or more paths. In multi-track recording, multiple sound sources are recorded from separate microphones to
individualized audio paths. down-mixing is the process of combining those audio paths to produce one or two paths that
include all content.
Dante Audio Switching Board down-mix Input
Dante Audio Switching Output Boards provide the ability to down-mix the audio signal from one input (must be assigned
as the down-mix input) to stereo audio.
The down-mixed input is fed from a single selectable embedded audio input from any Enova DGX Input Board. While the
sample rate can be any valid rate, the data will be sample rate converted to 48 kHz. down-mixed audio from a single
input can be switched to any or all embedded or Dante-connected audio outputs.
Supported down-mix Input Formats
Dolby TrueHD
Dolby Digital Plus
Dolby Digital
DTS-HD Master Audio
DTS-HD High-Resolution Audio
DTS
2 CH through 8 CH L-PCM
Routing the down-mix Input
The down-mix input is selected from the available audio inputs and is routed the same as any other audio input to any or
all outputs (for general switching and configuration instructions, including the down-mix input, see page 130).
down-mix SEND_COMMANDs
The down-mixed audio input uses a subset of the SEND_COMMANDs available for Dante Audio Switching Boards (see
below). For details on each of the SEND_COMMANDs that work with the down-mixed audio input, see the Audio Input
SEND_COMMAND section on page 231.

Dante Audio Switching Board Troubleshooting
Switching speed or command response slows after adding Dante ASBs to the enclosure:
Your Dante network may be attached to the Enova DGX’s ICSLAN Private network. If so, the ICSLAN Port may be
issuing DHCP addresses, flooding the network.
Remove the ICSLAN from the Dante network and configure the switch on your Dante network using IGMP
protocols to correctly configure your network settings (see Dante documentation at www.audinate.com).
Cannot find the Dante Audio Switching Board in Dante Controller:
Check that the network cable is plugged in, and that the activity lights are flashing (fairly rapidly).
Check that the correct network interfaces are selected. The selected network interfaces can be changed via the
"interface selection" button in the main Dante Controller toolbar.
Check that your network interfaces have the correct IP addresses (or set to acquire IP addresses automatically).
Check that you have no Antivirus software installed (Dante uses ’unusual’ port addresses, due to the ’usual’ port
addresses already being used by other common applications) - please see the Dante Controller user guide for
details.
Check that you have no firewall active - please see the Dante Controller user guide for details on how to safely
configure a firewall for use in a deployed network.
To determine which physical Dante device corresponds to an entry in Dante Controller:
Double click any device in the Network View to open the Device View, then click the Identify button. This causes
LEDs on the device to flash (note that not all Dante devices support this feature).
