The M-Audio Delta 44 Sound Card offers the same features and high performance as their Delta 66 card, but is designed for those who do not require S/PDIF digital I/O. The Delta 44 features the same 24 bit 96kHz converter section, and like the Delta 66, the Delta 44's breakout box handles four balanced or unbalanced, + 4dB or - 10dB signal level analog inputs and outputs.

For use with both Mac and PC Configured as a PCI Host card with external audio break-out box to minimize noise induced from the computer 4 Input & 4 output TRS connections 24-Bit support throughout Powerful digital mixing, routing and monitoring capabilities with included software Full duplex recording interface

Recently decommissioned from pro working sound studio.

I have used this with Windows and Linux computers. There are also drivers for Mac.
