5 Operational Overview
5.1 Signal Flow
As shown in the signal flow diagram below, the
AES16 with its on-board digital mixer provides
extensive signal routing capabilities that can
adapt to any studio requirement. The mixer is
implemented using a proprietary digital signal
processor (DSP) that is optimized to maintain
low latency and high signal quality.
The architecture of the digital mixer consists of
16 record channels and 16 play channels that are
accessible to host applications as eight stereo
record devices and eight stereo play devices.
Submixers on each output provide low-latency
mixing for record monitoring and output mixing.
