The Delta 44 offers the same features and high performance as the Delta 66, but is designed for the person who does not require S/PDIF digital I/O. The Delta 44 features the same 24-bit 96kHz converter section that makes the Delta 66 the envy of the audio card community. And like the Delta 66, the Delta 44s breakout box handles 4 balanced or unbalanced, +4dB or -10dB signal level analog inputs and outputs. Also included is the Delta control panel software, which configures the card and controls digital mixing and routing.
