PCI Host Adapter Card:
11. Host Cable connector 1: This 15-pin D-sub connector attaches to the supplied
breakout cable #1 to allow communication between the PCI host card and
external digital devices.
12. Host Cable connector 2: This 44-pin D-sub connector attaches to the supplied
breakout cable #2 to allow communication between the PCI host card and
external analog devices.
13. Line Level Jumper #1: This jumper set allows you to switch the XLR analog
input #1 level setting from balanced microphone level to a +4dBu line level
setting. The default setting shown is the microphone level setting.
14. Line Level Jumper #2: This jumper set allows you to switch the XLR analog
input #2 level setting from balanced microphone level to a +4dBu line level
setting. The default setting shown is the microphone level setting.
Setting the Jumpers
The Delta 1010LT’s PCI card has two sets of jumpers that can be used to control the
operating line level for the 1010LT’s analog inputs 1&2 on XLR jacks. The location of
these jumpers is illustrated in the previous section under “PCI Host Adapter Card.”
Two basic settings are possible, one for a microphone line level compatible with
low impedance dynamic microphones (those that do not require phantom power,
such as condenser mics), and the other is an operating line level of +4dBu
(typical for balanced line levels). Two variations are possible for each of these
line level settings. This is shown in the illustrations below.
The default setting when you receive your 1010LT is with the jumpers set to the
microphone line level setting. If you wish to use either or both inputs 1&2 as a +4dBu
line level input, then you will need to change the jumper setting on the 1010LT PCI card.
