SDI Input Audio Monitoring Delay

Add audio delay to the SDI input signals in 1 ms increments up to 160

ms to provide lip sync. You can then output these delayed signals as

needed through the de-embedded AES output ports or the optional

AES and analog output ports. The effect of the delay can be audibly

monitored continuously as it is changed. Refer to How Do I

Synchronize External Surround Sound Audio with Video? on page 36

for details.

When using this delay in conjunction with the audio monitoring delay,

you can create a total delay of up to 330 ms before routing the audio to

the internal speakers. When multiple SDI input cards are installed in an

AMP2-16V, the SDI input delay of each card is separately adjustable.

SDI Output Re-Embedding

The 3G SDI I/O cards can be used to re-embed the selected SDI source.

Audio from other AMP2-16V inputs that are clocked by a 48kHz clock

locked to the SDI input can be re-embedded into the reclocked 3G SDI

I/O Output stream. This means that audio channels within the SDI

stream can be rearranged and/or delayed, or even replaced by audio

from other 3G SDI cards, or from other inputs. Refer to 3G SDI I/O

Configuration Menu on page 86 for more information.

Toslink (SPDIF) Optical Input

One or more optical channel pair inputs are now available as part of

optional Analog I/O Cards. This would typically be used for auxiliary

monitoring purposes. This optical input is equipped with a sample rate

converter so that its clocking may be independent from the clocking of

all of the other inputs.Refer to the How Do I Select the Inputs I Want to

Hear in the Speakers? on page 28 for details.
