2470HD Time Delay
Video Mode
Four radio buttons select the Video Mode, which includes the frame rate and video format. These are:
59.94 Hz / 720p
59.94 Hz / 1080i
50 Hz / 720p
50 Hz / 1080i
This setting can only be changed when the Time Delay is stopped. When it is changed, the
unit will display a warning and then automatically perform a quick restart to initialize in the newly
selected mode.
Audio Input Source
Three radio buttons select the input source for audio. These are:
SDI Embedded Audio
AES Digital Audio (when optional DXP-5 interface is connected)
Analog Audio
The Analog audio inputs are the pair of +4 dBu analog XLR inputs on the rear panel.
This setting can only be changed when the Time Delay is stopped.
Regardless of the input selected, audio will always appear in parallel, both in the
embedded audio HD-SDI stream, the analog XLR outputs and the optional DXP-5 AES/EBU
outputs. The input selection affects how many channels are available. With Analog, channels 1
and 2 are active and channels 3-16 will carry silence on embedded audio and AES/EBU outputs.
With AES/EBU selected, channels 9-16 of the embedded audio output will carry silence.
The 2470-HD Time Delay supports embedded audio in groups 1-4, which includes Audio
Channels 1-16, providing 24-bit,
48 KHz, synchronous audio, as per SMPTE 299M.
