If required, make certain Rear I/O Module(s) are installed before installi ng the 9301 into the frame slot. Damage to card and/or Rear I/O Module can occur if module installation is attempted with card already installed in slot.

If card resists fully engaging in r ear I/O module mating connector, check for alignment and proper insertion in slot tracks. Damage to card and/or rear I/O module may occur if improper card insertion is attempted.

Introduction 9301 Functional Description

9301 Functional Description

Figure 1-1 shows a functional block diagram of the 9301. The 9301 AES audio delay provides independent delay settings (from 0.20 msec to 21 seconds) for up to eight AES channel pairs. All received AES signals are sample rate converted to match a common output timing. The output timing can be locked to the AES input timing, a black burst or tri-level video reference s ignal, or the card’s internal clock.

In addition to the delay function, the 9301 also provides audio routing that acts as a full audio cross point. Each of the 16 AES output channels can receive signal from any one of the 16 AES input channel s or four internal tone generators. Unused output channels can be mapped to a “Silence” source. Each output also provides gain adjustment and selectable polarity inversion.

9301-OM (V4.2) 9301 PRODUCT MANUAL 1-5

1 9301 Functional Description

9301 Input/Outputs

The 9301 provides the following video inputs and outputs:

• Inputs:

• AES I/O (1-4) – user-switchable as AES inputs or AES outputs

• AES IN (5-8) – dedicated AES inputs

• Outputs:

• AES I/O (1-4) – user-switchable as AES inputs or AES outputs

• AES OUT (1-8) – dedicated AES outputs

Note: The input/output complement listed above represents the maximum capability

of the 9301. The practical input/output complement is determined by the particular Rear I/O Module used with the 9301. Refer to 9301 Rear I/O Modules (p. 1-15) for more information.

AES Audio Input Format

The 9301 accepts up to 16 channels (8 pairs) of discrete AES audio on 75-ohm BNC connections per AES-3id/SMPTE276M. The AES must have a nominal rate of approximately 48 kHz. Sample rate conversion can be employed to account for minor clock rate differences in the AES stream and an external reference (if used). However, the 9301 does not support AES input at 32 kHz, 44.1 kHz, 96 kHz or 192 kHz rates.

AES Audio Output Format

The 9301 provides up to 16 channels (8 pairs) of discrete AES audio on 75-ohm BNC connections per AES-3id/SMPTE276M. The output clock rate of each pair is precisely locked to input AES timing, frame reference timing, or the card’s internal independent timing.

Audio Delay and Timing Function

Delay controls for each AES output c hannel pr ovide i ndependentl y adjus table Input/Output delay ranging from 0.20 msec to 21 seconds (21000.00 msec). Audio data blocks are sequentially held in independent buffers and released per the delay setting at the intervals dictated by the delay setting and the user-selected timing reference source.

The 9301 allows selection from the following reference timing sources:

• AES Input – T iming is deri ved from the lowest -numbered AES input

BNC that is used. (For example, if are used,

AES IN 8 being accordingly re-sampled).

AES IN 3 serves as the timing master wit h AES IN 5 and

Using AES input reference timing, all outputs can for example be slaved to a DARS reference by simply connecting the DARS reference to the lowest-numbered AES input being used. In this manner, all other inputs will be re-sampled to sync with the DARS channel.

AES IN 3, AES IN 5, and AES IN 8

Audio Routing Description

• Reference 1 and Reference 2 Frame References – Timing is

derived from an external frame sync reference signals distributed with the card frame (

Ext. Frame Ref IN in Figure 1-1), thereby

allowing the audio to be synchronized to a black burst or tri-level video reference.

• Local – Timing is derived from the card’s internal clock with no

association to external signal t iming.

The audio processor operates as an internal audio router. The router function chooses from the following inputs:

• 16 channels (8 pairs) of discrete AES input

• Four independent internal tone generators (described below)

• Digital silence (mute) setting

The router function in turn provides 16 channels of discrete AES output on eight AES pairs.

The router acts as a full audio cross point. Each of the 16 AES output channels can receive signal from any one of the 20 input sources (16 discrete AES input channels, or any of four internal tone generators). Unused output channels can be mappe d to a “Silence” source. Each output al so provi des gain adjustment and selectable polarity inversion.

9301-OM (V4.2) 9301 PRODUCT MANUAL 1-7

1 9301 Functional Description

Output audio rates are always 48 kHz locked to the selected reference, but discrete AES inputs can be set to bypass the sample rate converters to align these inputs with the output timing (AES must be nominally 48 kHz input). The sample rate converters are enable d (bypass turned of f) by defaul t. Outpu t AES is always precisely synchronized with the selected reference.

As set with the default settings, the routing between AES input channels and AES output channels is basic 1-to-1 (AES Ch 1 input is routed to AES Ch 1 output, and so on). Other sources and/or destinations for each channel are selected (from the choices listed above) using the card edge controls or a remote control system.

Note: As shown in Figure 1-1, the 9301 is equipped with eight discrete AES input

pair ports and eight discrete AES output pair ports. On Rear I/O Modules having limited AES I/O capabilities, switches S11 thru S14 allow available rear module BNC connectors to be allotted between AES inputs and outputs as desired. Buffered copies of and as respective outputs fed through S11 – S14 on the 9301 card.

Tone Generator Function

The 9301 contains four built-in tone generators (Tone Generator 1 thru Tone Generator 4). Each of the four tone generators can be set to a different frequency, and are available as audio sources for each AES audio output.

18 discrete sine wave frequencies are a vailable, ranging from 50 Hz to 16 kHz (default frequency is 1.0 kHz).

Audio Routing Example

Figure 1-5 shows an example of using the 9301 audio routing functions to route the audio to discrete outputs for post-production processing (in this example, a console used for post-production EQ, levels, and monitor), and finally redirect AES audio to selected output channels. In the example, delay can be applied to the

AES 1 thru AES 3 paths. An internal tone generator is also applied to an

available AES output channel (AES Ch 6). In this example, unused channel outputs (AES Channels 9, 10, and 16) are set to Silence.

Parameter changes made by any of these means are universally accepted by the card (for example, a change made using the card edge controls will change the setting displayed on DashBoard™ and a Control Panel; a change made using DashBoard™ will similarly change the setting displayed on a Control Panel and the card itself).
