Accuphase DC-91

MMB Digital Processor (1994-98)
The revolutionary MMB (Multiple Mufti-Bit) system with 16 strictly selected D/A converters connected in a parallel configuration assures perfect linearity and reduces noise to the absolute theoretical limit of 20-bit system.
To accommodate the digital signal form the DP-90, an HPC optical link as well as HPC balanced connectors are provided.
Pulse distortion and jitter are virtually absent, assuring absolutely flawless signal, locking itself onto the optimum setting.
A total of 13 digital inputs, 2 outputs, and provisions for 3 digital records cover all the bases.
This is simply the finest digital audio processor, for now and for the future.
