Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- === Ji-woo Popov === Dept of Electrical Engineering, UC Berkeley Department of EECS "Do not worship the copy."
