====== Details ======

The Delta PCI cards have been around since 2000 (?) and have long been well supported in Linux via the ice1712 driver, which should be included in most distributions. They handle various bit rates and depths up to 24 bit/96kHz. As of 2012 all these interfaces are still being manufactured.

Apart from the 1010LT the cards come with break-out boxes with 1/4" jack sockets.

The optional Omni I/O box replaces the Delta 44 or 66 breakout box with one that has 2 microphone pre-amps with phantom power (these also accept 1/4" instrument jacks), 2 stereo auxiliary inputs, effects sends, 2 headphone outputs with independent volume controls and a master volume. The Omni is no longer available new, but some can be found on ebay.

====== Software ======

[[http://sourceforge.net/projects/kenvy24/|KEnvy24]] is a KDE version.
