Hardware Installation

Changing the jumper setting is easy to do when the 1010LT PCI card is not installed in the computer. Since it is usually impossible to change the jumpers while the card is in the computer, it’s a good idea to make a decision now. If you wish to connect a dynamic or ribbon microphone directly to the Delta 1010LT’s XLR analog inputs 1&2, then leave the jumpers set to their default setting, +4dBu. If you wish to connect the XLR analog inputs 1&2 to the output of a balanced +4dBu device such as a pre amp or dynamics processor, you will need to change the jumper setting.

Remember that you can change one set of jumpers and not the other, if that suits your needs. To change the jumper:

1.Before removing the Delta 1010LT PCI host card from its protective anti-static bag, touch the metal power supply case of the computer in order to dissipate any static electricity your body may have accumulated. You might want to pick up a grounding wrist strap (available from electronics stores like Radio Shack) if you want to be doubly sure you aren't carrying a static charge that could damage the card.

2.Either hold the PCI card in your hand, or place it on an anti-static surface (such as its protective bag). Using your fingertips or a tweezer, remove the plastic jumper that is covering the top-most and middle metal pins. See Illustrations 1 and 1a, below.

3.Place the jumper over the middle and bottom-most metal pins. See Illustrations 2 and 2a, below.

NOTE: Illustrations 1a and 2a show a variation on the mic level setting and the line level setting, respectively. If you find that your signal is too hot using the +4dBu selection in the Delta Control Panel’s “Variable Signal Level” section of the Hardware Settings page, then try these alternate settings.

To mechanically install the Delta 1010LT, do the following:

1.Turn off your computer and unplug the AC cord.

2.Remove the computer’s cover and position the computer so that you may easily access its PCI slots.
