Congratulations on choosing the openGear
ADM-188 AES Audio Delay
. The ADM-188 is part of a
full line of modular conversion gear for broadcast TV environments. The Sierra Video Systems
openGear
line includes video decoders and encoders, audio embeders and de-embeders, distribution
amplifiers, format converters, and much more. Sierra openGear
modular conversion gear will meet
your signal conversion needs now and well into the future.
Should you have questions pertaining to the installation or operation of your ADM-188, please contact
us at the numbers listed on the back cover of this manual. We are happy to help with any questions
regarding this or any other openGear
card.
Overview
The ADM-188 is a high quality AES audio delay capable of delaying up to 8 AES channel pairs. The
delay range spans from as little as 8.3 ms to as much as 5.461 seconds. All input AES signals are
sample rate converted to match a common output timing. The output timing can be locked to the AES
input timing, or a black burst or tri-level video reference signal.
Beyond audio delay, the ADM-188 can also provide AES audio routing. On the input side of the router
are the up to 16 channels (8 pairs) of discrete AES input. On the output side are the up to 16 channels
(8 pairs) of discrete AES output. The router acts as a full audio cross point: each of the 16 output
channels can receive signal from any one of the 16 input channels. Output channels can also be mapped
to a “silence” source. Each output allows independent gain adjustment and optional polarity inversion.
All card configuration is done with a simple front panel menu. There is a four character text display to
view and control parameters, and a toggle switch and two buttons to navigate the menu.
