This product is intended to be a component product of the openGear frame. Refer to the openGear frame Owner’s Manual for important safety instructions regarding the proper installation and safe operation of the frame as well as it’s component products.

Certain parts of this equipment namely the power supply area still present a safety hazard, with the power switch in the OFF position. To avoid electrical shock, disconnect all A/C power cords from the chassis' rear appliance connectors before servicing this area.

Service barriers within this product are intended to protect the operator and service personnel from hazardous voltages. For continued safety, replace all barriers after any servicing.

This product contains safety critical parts, which if incorrectly replaced may present a risk of fire or electrical shock. Components contained within the product’s power supplies and power supply area, are not intended to be customer serviced and should be returned to the factory for repair.

To reduce the risk of fire, replacement fuses must be the same type and rating. Only use attachments/accessories specified by the manufacturer.

Environmental Information

The equipment that you purchased required the extraction and use of natural resources for its production. It may contain hazardous substances that could impact health and the environment.

To avoid the potential release of those substances into the environment and to diminish the need for the extraction of natural resources, Sierra Video Systems encourages you to use the appropriate take-back systems. These systems will reuse or recycle most of the materials from your end-of-life equipment in an environmentally friendly and health conscious manner. The crossed-out wheeled bin symbol invites you to use these systems.

If you need more information on the collection, reuse, and recycling systems, please contact your local or regional waste administration. You can also contact Sierra Video Systems for more information on the environmental performances of our products.

A Word of Thanks

Congratulations on choosing the openGear ADC-163 Analog Audio to AES Converter. The ADC163 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 ADC-163, 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 ADC-163 is a high quality A to D converter capable of converting up to 8 channels of analog audio into four pairs of AES audio. Analog audio is differential input and sampled at 48 kHz with 0 dbFS digital equivalent to a +24 dBu analog.

Beyond analog to digital conversion, the ADC-163 can also provide AES audio routing. Any of the 8 analog audio inputs can be mapped to any of the 8 AES audio outputs. The gain and phase can also be adjusted on any of the audio channels.

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.

Supported Audio Formats

Discrete AES Audio Output

The ADC-163 can emit 8 channels (4 pairs) of discrete AES audio on 75 ohm BNC connections. The output clock rate of each pair is precisely locked, and derived from the input AES, or the frame reference.

Inputs and Outputs

The input and outputs of the ADC-163 are the following:

Inputs:



8 Analog Audio differential

Outputs:



4 dedicated AES pair output connections. (AES channels 1-8)

Signal Timing

The input AES audio rate must be 48 kHz (± 1%) nominally. There are sample rate converters on each input that allow the use of asynchronous sources, but the rate must be 48kHz. The output clock rate will be 48 kHz as defined by the AES input, or the frame video reference, depending on user selection.

In the case where DARS input is selected as the reference, the timing will be taken from BNC 10. Consequently, to slave the output timing to a DARS audio reference, simply connect it to BNC #10 and all other inputs will be re-sampled to match that channel.

To match the output audio clock to a video reference, select the frame reference (“Reference 1” or “Reference 2”). The card will automatically detect any black burst or tri level format (NTSC, PAL, 1080i, 720p) and generate a 48 kHz output clock accordingly.
