Overview
The 9345 is an analog to AES/EBU digital audio converter designed for broadcast use. It
provides digital to analog audio conversion along with AES/EBU signal distribution.
The 9345 supports audio sampling frequencies from 30kHz to 192 kHz. It converts the
incoming stereo analog audio signal to an AES/EBU digital audio signal using 24 bit
conversion technology.
The 9345 is housed in the openGear 8300 series frames.

conversion.
• Converts analog audio to AES/EBU digital audio and provides AES/EBU
signal distribution
• Can synchronize to frame, external or internally generated reference signals
• Internal clock generates audio sampling frequencies from 32kHz to 192 kHz
• 24-bit technology provides the highest quality signal conversion
• 5-year warranty
• Fits openGear 8300 series frames
Documentation Terms
The following terms are used throughout this guide:
• “Frame” refers to the 8310 or the 8320 frame that houses the 9345 card.
• “Operator” and “User” refer to the person who uses the 9345.

ESD
Susceptibility
Static Discharge
Whenever handling the 9345 and other r elated equipment, please observe all s tatic discharge
precautions as described in the following note:
Static discharge can cause serious damage to sensitive
semiconductor devices. Avoid handling circuit boards in
high static environments such as carpeted areas, and
when wearing synthetic fiber clothing. Always exercise
proper grounding precautions when working on circuit
boards and related equipment.
Unpacking
Unpack each 9345 you received from the shipping c ontainer, and check the c ontents against
the packing list to ensure that all item s are included. If any items are missing or damaged,
contact your sales representative or Cobalt Digital Inc. directly.

Rear Module
If you are installing the card into a slot with no rear module, you should have ordered and
received one rear module. You will need to install it in your frame before you can connect
cables.
Use the following steps to install a rear module in a frame:
1. On the rear of the frame, locate the card frame slot.
2. 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
3. Align the top hole of the rear module with the screw hole on the top edge of
the frame back plane.
4. Using a Phillips driver and the supplied screw, fasten the rear module to the
frame back plane. Do not over tighten.
11
This section provides instructions for connecting cables to 9345 rear modules. Connect the
input and output cables according to the following diagram. Split rear m odule RM20-9345-B/S
allows two cards to be installed in adjacent slots. Both of the rear modules shown are
compatible only with 20-slot frames (R M-9345-B rear m odule is for use with 8310-series ( 10slot) frame).
