Delta 44

Professional 4-In/4-Out Audio Card

Need a great sounding audio interface without digital I/O? The Delta 44 offers the same features and high performance as the Delta 66, but is designed for the user who does not require digital I/O. And like its big brother, the Delta 44’s breakout box handles four balanced/unbalanced, +4dBu or -10dBV signal level analog inputs and outputs. You get the same 24-bit/96kHz fidelity, industry-standard driver support and bulletproof operation as is found across the entire Delta family.

36-bit Embedded DSP

All Delta cards contain a 36-bit embedded DSP enabling a software-driven patchbay/router for all analog and digital I/O—all with extremely fast throughput for low-latency software monitoring. A single unified control panel provides settings for clock and sample rates, buffer sizes, individual signal levels for every input and output, and adjustable +4dBu/-10dBV pad controls. All controls are also easily accessible through most professional audio software applications for seamless integration and operation.
