The M-Audio Delta 44 is a high grade professional sound card. When setup properly for
use with the SDR-1000, the results speak for themselves. Unbelievably high dynamic
range and crystal clear audio with this card when combined with the versatile SDR-1000
results in an ear pleasing experience that is out of this world.
This page is designed to help you setup your new Delta 44 sound card for use with the
SDR-1000. Below you will find a step-by-
step guide (7 steps) along with tips for getting the
fastest support. If you have questions that are not addressed in this guide, the [Flexradio]
Email Reflector and the Flex-Radio-Friends Teamspeak Server are available for fast,

CAUTION:
It is extremely important to use the settings in the Delta Control Panel as
described below in order not to damage the SDR-1000 hardware due to overdriving the
audio. Make sure the output is set to -10dBv as shown in the screenshots below.
The OEM version of the Delta 44 that FlexRadio ships comes with three components: A
PCI card, the "breakout" box, and a cable to connect the two. We optionally ship the four
sets of cables necessary to connect the sound card to the SDR-1000 (1/8" stereo to dual
1/4" balanced).
