Introduction

Important

Read this file only if you are an advanced user who knows how to use the connector pin assignments. If you want to redirect your computer's sounds to external speakers, you should also be familiar with your computer's motherboard and know where to find the internal speaker.

Not all the connectors described here can be found on your card. To see the available connectors on your card, refer to the printed documentation.

You may want to connect other devices (such as a CD-ROM drive) in your computer to your audio card.  Or, you may want to redirect the "beeps" that you hear from your computer to external speakers.


Redirecting PC Sounds to External Speakers

It is possible to redirect the sounds that normally come from your computer's speaker to the speakers connected to your audio card. Once you do this, however, you will not be able to hear POST beeps (computer beeps made during power-on self test).

To redirect your computer's sounds to external speakers

1	Locate and remove the PC Speaker connection from your motherboard.

2	Connect a wire from the +5V DC pin of the motherboard's speaker connector to pin 1 of your card's PC Speaker connector.

3	Connect another wire from the PC Speaker Out pin of the motherboard's speaker connector to pin 2 of your card's PC Speaker connector.

Note

You should seek help from an experienced technician to perform this task.
