Overview

Congratulatio ns on choosing the openGear 9301 AES Audio Delay. The CDI-9301 is part of a full line of modular conversion gear for broadcast TV environments. The Cobalt Digital openGear line includes video decoders and encoders, audio embeders and de-embeders, distribution amplifiers, format converters, and much more. Cobalt 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 9301, 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.

The 9301 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 9301 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.
