Introduction This chapter contains the following sections: • Overview • Functional Block Diagram • Features • Documentation Terms Overview The 9252 is an AES/EBU distribution amplifier designed for broadcast use. It provides eight copies of the incoming signal. The 9252 supports audio sampling frequencies from 30kHz to 192 kHz. Cable equalization and reclocking techniques enable the 9252 to recover the incoming digital audio signal reliably. The 9252 is housed in the openGear 8310-C series frames.
Features The following features make the 9252 the best solution for digital audio distribution. • Cable equalization and data reclocking on the incoming AES/EBU signal • Supports audio sampling frequencies from 30kHz to 192 kHz • 5 year warranty • Fits openGear 8310-C series frames Documentation Terms The following terms are used throughout this guide: • “Frame” refers to the 8310-C frame that houses the 9252 card. • “Operator” and “User” refer to the person who uses the 9252.
Installation and Setup This chapter contains the following sections: • Static Discharge • Unpacking • Rear Module Options • Board Installation Static Discharge Whenever handling the 9252 and other related equipment, please observe all static discharge precautions as described in the following note: ESD Susceptibility Static discharge can cause serious damage to sensitive semiconductor devices.
Rear Module Installation If you are installing the card into a slot with no rear module, you should have ordered and received one of the RM-9252-A module. 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.
Rear Module Options This is a drawing of the RM-9252-A rear module to be used in the 10 slot 8310-C frame only. Figure 3. Rear Module Board Installation Use the following procedure to install the 9252 in an openGear 8310-C Series frame. 1. Refer to the User Manual of the openGear 8310-C series frame to ensure that the frame is properly installed according to instructions. 2.
