Chapter 4 Features

Audio Monitoring Delay

This unit requires all inputs that are being mixed or monitored to be

synchronous (i.e., have the same sample rate based on a common

clock). Inputs that are not synchronous with the selected clock source

will be automatically muted. Refer to the How Do I Set the Clock

Source? on page 53 for details.

Audio Monitoring Delay

Add monitored audio delay to the internal speakers in 1 ms increments

up to 170 ms to provide lip sync. The effect of the delay can be audibly

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

Synchronize Internal Speaker Audio with an External Video Source? on

page 34 for details.

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 35

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.

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.
