Introduction In This Chapter This chapter includes the following sections: • A Word of Thanks • Overview • Functional Block Diagram • Features • Documentation Terms A Word of Thanks Congratulations on choosing the openGear 9301 AES Audio Delay. The 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.
Supported Audio Formats Discrete AES Audio Input The 9301 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The AES must have a nominal rate of approximately 48 kHz. Sample rate conversion is employed to account for minor clock rate differences in the AES stream and the input video stream. However, the card does not support AES input at 32 kHz, 44.1 kHz, 96 kHz or 192 kHz rates.
Functional Block Diagram This section describes the basic operation of your 9301 product. Audio Control: 8 pairs 16 channels AES Decode and Sample Rate Conversion Routing Gain Polarity Audio Delay (5.461 Seconds Max) AES Encode 8 pairs 16 channels 9301 Block Diagram Figure 1. Simplified Block Diagram of 9301 Functions AES signals are received on the input BNCs. AES audio is sample rate converted to match the selected clock source. AES routing, gain, and polarity are then applied.
Installation and Setup In This Chapter This chapter includes the following sections: • Static Discharge • Unpacking • Rear Module Installation (Optional) • Board Installation • BNC Labels • Cable Connections • LEDs and Buttons • Switch 3 and 4 – Rotary Switch Settings and LED reporting Static Discharge Whenever handling the card and other related equipment, please observe all static discharge precautions as described in the following note: Static discharge can cause serious damage to sensit
Rear Module Installation (Optional) If you are installing the card in a 8310-C-BNC or 8310-BNC frame (one with a 100 BNC rear module installed across the entire back plane), skip this section. If you are installing the card into a slot with no rear module, you should have ordered and received one of the following modules; RM-9301-B or RM-9301-C. You will need to install it in your 8310 frame before you can connect cables. Use the following steps to install a rear module in an 8310 openGearTM frame: 1.

Board Installation Use the following steps to install the card in the openGearTM 8310 frame: 1. Warning Refer to the Owner’s Manual of the openGearTM 8310 frame to ensure that the frame is properly installed according to instructions. Heat and power distribution requirements within a frame may dictate specific slot placement of cards. Cards with many heat-producing components should be arranged to avoid areas of excess heat build-up, particularly in frames using convection cooling. 2.
Card Control and Status Card Status The card indicates the status of the input signal with the four blue LEDs labled with the different supported formats (1080, 720, 625, 525). When the card has locked to a particular input format, that LED will be illuminated. When the card has not locked to a particular video format, the card will search all possible formats, and the lights will cycle rapidly. Menu Navigation The card can be configured from a menu system built in to the front card edge.
Proc Saturation This is Chroma (C channel) gain, expressed as a percentage. It ranges from 0.0% to 200.0% in 0.1% steps. Proc Phase This is Chroma (C channel) phase adjustment, expressed in degrees, ranging from –360 to +360 in steps of one degree.
Display Orientation This parameter lets you change the orientation of the display. “Vert” makes the characters look correct when the cards are mounted in a 2 RU frame like the 8310. “Horz” makes the characters look right in a horizontal frame. Display Brightness This parameter allows you to set the standard output brightness of the menu display. It is a percentage of maximum brightness.
Software Build Number A read only indication of the software build number. Software build number is an internal indicator used by Cobalt engineers to differentiate different software builds. Factory Default Settings The factory default settings are as follows 1) The proc module is enabled, but all parameters are set to unity. 2) The audio mapping is for each AES input to be routed to its respective AES output, for example AES IN 1 to AES OUT 1.
Remote Control In This Chapter This section provides a detailed explanation on using remote control functions with your card. DashBoard Control System Software The DashBoard Control System enables you to monitor and control openGearTM frames and controller cards from a computer. The DashBoard software and manual can be downloaded from the Cobalt Digital Inc. website (www.cobaltdigital.com).
