A Word of Thanks
Congratulations on choosing the openGear 9341 Analog Audio to AES Converter. The 9341 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 9341, 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 9341 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 9341 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 9341 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 9341 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.

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-9341-B or RM-9341-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. Refer to the openGearTM 8310 frame Owner’s Manual, to ensure that the frame is
properly installed according to instructions.
2. On the rear of the 8310, locate the card frame slot.
3. As shown in Figure 2, seat the bottom of the rear module in the seating slot at the
base of the frame’s back plane.
Figure 2. Rear Module Installation
4. Align the top hole of the RM-9341-C with the screw hole on the top edge of the 8310
back plane.
5. Using a Phillips driver and the supplied screw, fasten the rear module to the 8310
back plane. Do not over tighten.
All modules are installed using the same method above.
The following section contains a table of the optional rear modules available for the 9341.

Board Installation
Use the following steps to install the card in the openGearTM 8310 frame:
1. 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.
Warning
2. After selecting the desired frame installation slot, hold the card by the edges and
carefully align the card edges with the slots in the frame. Then, fully insert the card
into the frame until the rear connection plugs are properly seated on the midplane and
rear modules.
This completes the procedure for installing the card in the openGearTM 8310 frame.

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), these LEDs correspond to AES Inputs 1-4. The four orange
LEDs labeled User 1-4 correspond to AES Inputs 5-8 respectively. When the card has locked to an
AES signal, a corresponding LED will be illuminated. When the card has not locked to an AES signal,
the card will search for a signal and the lights will cycle rapidly.
Menu Navigation
The card can be configured from a menu system built in to the front card edge. This provides an
intuitive and easy to use method for exploring and using the features of the card.
The menu is navigated by using the toggle switch and the two push buttons. The lower button is the
“Enter” button to enter a submenu, and the upper button is the “Exit” button to exit a submenu. Moving
the toggle switch up or down moves up or down in menu choices, and pressing the buttons moves in or
out of sub menus.
The menu LEDs will illuminate from top to bottom to indicate increasing depth in the menu.

Output Source
Because the cards audio system functions like a router, each output can be sourced from any input
channel. This parameter lets you choose from the many different sources. Here is an explanation of the
different source names:
Source Name Description
AnXX
TgX
Analog Audio channel X (1 through 8)
Test Generator channel X (1 through 4)
Output Gain
The gain of each output is adjustable from -40dB to +40dB in 0.1 dB steps. A setting of 400 is
equivalent to +40dB.
Output Polarity
If set to “Norm” output polarity is the same as input polarity, if set to “Inv” the output polarity is
inverted. This can be used to correct polarity errors in the input signals fed to the card.

Tone Frequency
This sets the frequency of the test tone for each of the four tone generators. Each of the four tone
generators TG1 – TG4 can be set to a different frequency, and are available as audio sources for the
embedded or AES audio outputs. The tones can range from 50Hz to 16kHz.

Troubleshooting Checklist
Warranty and Repair Policy
Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your
card, the following basic troubleshooting checklist may help identify the source of the problem. If the
module still does not appear to be working properly after checking all possible causes, please contact
your openGear products distributor, or the Technical Support department at the numbers listed under
the “Contact Us” section at the end of this manual.
1. Visual Review Performing a quick visual check may reveal many problems, such
as connectors not properly seated or loose cables. Check the module, the frame, and
any associated peripheral equipment for signs of trouble.
2. Power Check Check the power indicator LED on the distribution frame front
panel for the presence of power. If the power LED is not illuminated, verify that the
power cable is connected to a power source and that power is available at the power
main. Confirm that the power supplies are fully seated in their slots. If the power
LED is still not illuminated, replace the power supply with one that is verified to
work.
3. Reseat the Card in the Frame Eject the card and reinsert it in the frame.
4. Check Control Settings Refer to the Installation and Operation sections of the
manual and verify all user-adjustable component settings.
5. Input Signal Status Verify that source equipment is operating correctly and that a
valid signal is being supplied.
6. Output Signal Path Verify that destination equipment is operating correctly and
receiving a valid signal.
7. Module Exchange Exchanging a suspect module with a module that is known to
be working correctly is an efficient method for localizing problems to individual
modules.
8. Error Code E100 – If this error code is displayed, the 9341 is detecting clipping on
the analog audio input. Analog input levels must be lowered to avoid clipping.
