Safety Summary

Warnings

! WARNING !

Cautions

CAUTION

T o redu ce risk of electr ic shock do not remove line voltage service barrier cover on frame equipment containing an AC power supply. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

This device is intended for environmentally controlled use only in appropriate video terminal equipment operating environments.

This product is intended to be a component product of an 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 its component products.

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 only convection cooling. The 9341 has a moderate power dissipation (11 W max.). As such, avoiding placing the card adjacent to other cards with similar dissipation values if possible.

CAUTION

1-4 9341 PRODUCT MANUAL 9341-OM (V4.1)

If required, make certain Rear I/O Module(s) are installed before installing the 9341 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 9341 Functional Description

9341 Functional Description

Figure 1-1 shows a functional block diagram of the 9341. The 9341 receives up to eight balanced audio inputs and converts these into up to four AES-3id output pairs. The output timing can be locked to a DARS input timing, black burst or tri-level video reference signal, or the card’s internal clock.

The 9341 also provides audio routing that acts as a full audio cross point. Each of the eight AES outpu t channe ls can r eceive signal from any c ard inpu t source. Unused output channels can be mapped to a “Silence” source. Each output also provides gain adjustment and selectable polarity inversion.

AES Audio Output Format

The 9341 provides up to 8 channels (4 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 DARS timing, frame reference timing, or the card’s internal independent timing.

Audio Timing Function

Audio data blocks are sequent ially buf fere d and releas ed per the user -se lected timing reference source.

The 9341 allows selection from the following reference timing sources:

• DARS Input – All outputs can be slaved to a DARS reference when

DARS is selected. In this manner, all other inputs will be re-sampled to sync with the DARS channel.

• Reference 1 and Reference 2 Frame References – Timing is

derived fr om an external frame syn c reference signals distributed with the card frame ( allowing the audio to be synchronized to a black burst or tri-level video reference.

• Local – Timing is derived from the card’s in ternal clock w ith no

associatio n to external signal timing.

Audio Routing Description

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

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

• 8 channels of balanced analog audio inputs

• Four independent internal tone generators (described below)

• Downmix and mono mixers

• Digital silence (mute) setting

The router function in turn provides 8 channels of discrete AES output on four AES pairs.

The router acts as a f ul l a udi o cr oss point. Each of the 8 AES out put ch anne ls can receive signal from any one of the card input sources. Unused output channels can be mapped to a “Silence” source. Each output also provide s gain adjustment and selectable polarity inversion.

Output audio rates are alwa ys 48 kHz l ock ed to the sel ected refe rence . Ou tput AES is always precisely synchronized with the selected reference.

As set with the default settings, the routing between analog input channels and AES output channels is basic 1-to-1 (

AES Ch 1 output, and so on). Other sources and/or destinations for each

AN-AUD Ch 1 input is routed to

channel ar e selected ( from the choices listed above) using the card edge controls or a remote con trol system.

Note: Upmix function is an optional licensable feature. This function and its controls

appear only when a license key is entered and activated. (This option (identified in Cobalt or field-activated using a key string which is sent to you when this option is purchased.)

The 2.0-to-5.1 upmixer function receives a normal PCM stereo pair from the Audio Routing/Gain Control function and upmixes the pair to provide 5.1 channels (Left ( Surround (

Ls), and Right Surround (Rs)). Whenever the upmixer is active, it

overwrites the six selected output channels with the new 5.1 upmix signals (including replacing the original source stereo

R signals).

The 2.0-to-5.1 upmixer can be set to up mix in any of three modes: Always upmix, Bypass upmix, or Auto enable/bypass upmixing. The Auto upmixing mode looks at the s ignal le vels on t he selec ted ch annels an d compar es them to a selectab le level threshold.

• If the upmixer detects signal level below a selected threshold on all

four of the selected channels designated as

C, LFE, Ls, and Rs, this

indicates to the upmixer that these channels are not carrying 5.1. In this case, the upmixer overwrites all six selected channels with the new 5.1 content.

• If the upmixer detects signal level above a selected threshold on any

of the four selected channels designated as

indicates t o the upmixe r that the ch annel(s) ar e already carrying viable 5.1 content. In th is case , the upmixe r is bypa ssed, al lowing t he original channels to pass unaffected.

The examples in Figure 1-4 show t he automatic enable/di sable up-mixing function applied to example selected channels

AES Ch 1 thru AES Ch 6. As

shown and described, the processing is contingent upon the signal levels of the channe ls selected to carry the new 5.1 upmix relative to the selected threshold (in this example, -60 dBFS). Note also that this function is applied after the Audio Routing/Gain Control function.
