Open Box Echo Indigo DJ Dual Stereo 24/96 PCMCIA Output Card Level 1

The Echo Indigo DJ 4-Channel PCMCIA Output Card has 2 independent stereo 1/8 inch analog outputs that let you cue mix on headphones while playing back the house mix on the other. Each output features 24-bit/96kHz converters, guaranteeing perfect sound reproduction.
 
The use of "virtual" outputs causes the Echo Indigo DJ to appear to computer software as if it has 8 separate outputs, which are then digitally mixed down to the physical outputs using Indigo DJ's console software and its onboard DSP. This makes the Indigo DJ output device compatible with all popular multitrack software. Echo's "multi-client" drivers permit running multiple apps simultaneously.
