Installing The Aieb1 I/O Expansion Board - Yamaha A4000 Owner's Manual

Installing the AIEB1 I/O Expansion Board

The optional AIEB1 Input/Output expansion board adds digital I/O (both optical and coaxial formats) and
six assignable outputs to the A5000/A4000. For information about the board's connectors and general
board setup, refer to information elsewhere in this manual.
• Before performing the installation, please read precautions "Handling and Installation of Options,"
found at the beginning of this manual.
[Procedure]
1.
Be sure that you have the following at hand before starting the installation.
• AIEB1 I/O expansion board: Confirm that there are 3 cables extending from the board.
• Phillips screwdriver: Magnetic-tipped screwdriver is recommended.
• Workbench: Please carry out all work on a stable workbench or table. Spreading a cloth over the work
surface will help prevent scratching.
• Gloves: Be sure to wear gloves so that your hands are not scratched by the metal cover or other metal
parts.
2.
Remove the top cover (page 232).
3.
Now go to the rear panel and remove the 3 screws (A) holding the I/O cover in place.
Take the I/O cover out.
• The I/O cover may fall inside the unit when all 3 screws are removed, so be sure to hold the I/O cover with one
hand while removing the screws.
• The I/O cover will not be needed as long as the AIEB1 is installed, but the screws with which it was attached
will be used to attach the AIEB1, so be careful not to misplace them.
