Loop through and E to E
SDA-00 E to E
SDA-00 models have an E to E path provided for monitoring purposes, as illustrated
in the following diagram.
When E to E mode is enabled, the play channel video and audio outputs are switched
to the corresponding record channel inputs when the play channel is in stop mode or
when no clip is loaded. The following table describes play channel operation
depending on the E to E selection.
If E to E mode is enabled, you can connect an external reference signal which is
synchronous to the video input. This eliminates artifacts on the play channel output
(periodic vertical shift) due to routing an asynchronous signal through the SDA-00 K2
Media Client. However, this is not required for recording, as the SDA-00 K2 Media
Client can record asynchronous signals.
NOTE: E to E is provided for monitoring the record channel, and is not intended
as a program switch.
