InstaGate Pro
®
Technology
InstaGate Pro Technology eliminates latency (time required for authentication) in the switcher for HDCP
negotiations with the displays in a system. The latency is typically experienced when HDCP
authenticates HDMI source and destination devices every time a new switching combination between a
source device and display occurs. With InstaGate Pro Technology, when a source requires HDCP
encrypted content, the inputs and compliant downstream devices are automatically authenticated – it just
works. Key limitations on source devices are also eliminated by allowing them to see only a single sink
key from the HDMI Input Board’s input connection.
Note: Some destination devices have a longer lag time than others between receiving a signal and
displaying that signal. Although InstaGate Pro significantly reduces the latency associated with
HDCP authentication, it cannot reduce the inherent lag time of a device as it syncs up to the newly
switched video image.
Troubleshooting Audio
Before troubleshooting audio, it helps to understand how the system handles EDID information.
The source reads and adapts to the pre-loaded EDID on the DGX HDMI input connector.
The factory default EDID is set to support 2 channel L-PCM audio. This EDID can be
modified by using one of the methods described under “Possible Solutions” on page 72.
Audio Format Support on Enova DGX Boards
The following table indicates which audio formats are supported by specific Enova DGX boards.
* Dolby Digital and DTS support up to 48 kHz, 5.1 channels.
Note: DVI Boards must have their EDID changed to support HDMI signals with embedded audio.
Important: Because signals routed through HDMI, DVI, and DXLink Boards in an Enova DGX
Switcher feature SmartScale Technology, they normally produce a quality image. If the installation
has special resolution or EDID requirements, see page 157.
