Overview

Features

The ADC-8434-A Quad Analog Audio to AES Converter is a broadcast quality, modular product
used to convert four analog audio channels to two, 24-bit, unbalanced AES-3id signals. The
ADC-8434-A accepts 4 analog audio signals (2 stereo pairs) and provides 2 copies of each of the
2 AES / EBU output signals.

The conversion from analog to digital is performed with 24-bit precision. The ADC-8434-A
supports sampling rates of 32kHz to 96kHz with AES (DARS) reference, video black reference,
or 48kHz internal reference. The AES output frequency (32kHz to 96kHz) can be determined by
the reference selected as long as it is a valid DARS Audio reference.

The following features make the ADC-8434-A the best solution for analog to AES conversion:

• 4 Channels of Audio Conversion

• Can synchronize to one of the two frame reference inputs, Digital Audio Reference
Signal (DARS)

• Internal clock generates audio sampling frequencies of 48kHz

• Supports audio sampling frequencies from 32kHz to 96kHz

• 24-bit technology provides the highest quality signal conversion

• 75ohm unbalanced AES-3id I/O

• Balanced Analog Audio I/O

• Provides level control of output signals

• 5-year transferable warranty

Installing the ADC-8434-A

This section outlines how to install a Rear Module in a DFR-8300 series frame. The same
procedure applies regardless of the frame or card type. However, the specific Rear Module you
need to install depends on the frame you are using. Note that Slot 1 is the left most slot as you
look into the openGear frame from the front.

Rear Modules for the ADC-8434-A

The Rear Module for the ADC-8434-A depends on the openGear frame you are installing the
card into. The following rear modules are required:

• DFR-8310 series frame — When installing the ADC-8434-A in the DFR-8310 series
frames, the 8310AR-036 Rear Module (R1A-8434) is required. The ADC-8434-A is not
compatible with the DFR-8310-BNC frame.

• DFR-8321 series frame — When installing the ADC-8434-A in the DFR-8321 series
frame, the 8320AR-036 Full Rear Module (R2A-8434) is required.

Installing a Rear Module

If the Rear Module is already installed, proceed to the section “Installing the ADC-8434-A” on
page 2-4.

Use the following procedure to install a Rear Module in your DFR-8300 series frame:

1. Locate the card frame slots on the rear of the frame.

2. Remove the Blank Plate from the slot you have chosen for the ADC-8434-A installation.

If there is no Blank Plate installed, proceed to the next step.

3. Install the bottom of the Rear Module in the Module Seating Slot at the base of the

frame’s back plane. (Figure 2.1)

Screw Hole

Module Seating Slot

5. Using a Phillips screwdriver and the supplied screw, fasten the Rear Module to the back

plane of the frame. Do not over tighten.

6. Ensure proper frame cooling and ventilation by having all rear frame slots covered with

Rear Modules or Blank Plates.

Installing the ADC-8434-A

Use the following procedure to install the ADC-8434-A in a DFR-8300 series frame:

1. Locate the Rear Module you installed in the procedure “Installing a Rear Module” on

page 2-3.

2. Hold the ADC-8434-A by the edges and carefully align the card-edges with the slots in

the frame.

3. Fully insert the card into the frame until the rear connection plus is properly seated in the

Rear Module.

4. Verify whether your Rear Module Label is self-adhesive by checking the back for a thin

wax sheet. You must remove this wax sheet before affixing the label to the rear module
surface.

5. Affix the supplied Rear Module Label to the BNC area of the Rear Module.

Troubleshooting Checklist

Routine maintenance to this openGear product is not required. In the event of problems with your
ADC-8434-A, the following basic troubleshooting checklist may help identify the source of the
problem. If the frame still does not appear to be working properly after checking all possible
causes, please contact your openGear products distributor, or the T echnical Support department at
the numbers listed under the “Contact Us” section.

1. Visual Review — Performing a quick visual check may reveal many prob lems, such as

connectors not properly seated or loose cables. Check the card, 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. Re-seat the Card in the Frame — Eject the card and reinsert it in the frame.

4. Check Control Settings — Refer to the Installation and User Control 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. Unit Exchange — Exchanging a suspect unit with a unit that is known to be working

correctly is an efficient method for localizing problems to individual units.
