USB Audio driver must be installed for the PC to
communicate with the MA12000.

Optical
The two Optical Inputs allow digital sources to be
connected to the MA12000 using TOSLINK cables
also known as “optical audio cables.” The Optical
Inputs can handle high resolution digital audio up
to 192kHz/24-bit. The MA12000 DAC will process
standard format SPDIF PCM signals as well as
Dolby Digital and DTS encoded multi-channel bit
streams. Unsupported formats can result in strange
and/or unpleasant sounds.
Coax
The two Digital Coax (Coaxial) Inputs allow digital
sources to be connected to the MA12000 using
Digital Audio RCA Coaxial Cables. The Coax
Inputs can handle high resolution digital audio up
to 192kHz/24-bit. The MA12000 DAC will process
standard format SPDIF PCM signals as well as
Dolby Digital and DTS encoded multi-channel bit
streams. Remember, unsupported formats can result
in strange and/or unpleasant sounds.
MCT
The Digital MCT Input Circuitry of the MA12000
directly decodes SACD/CD signals (as well as PCM)
from an external Transport component. With MCT,
a secure digital connection is created, allowing for
the playback of the high definition audio found on
SACDs. Regular CDs can also be played over the
MCT connection. Use an MCT cable to connect the
MCT din jacks from the source to the MA12000. The
Digital MCT Cable is a McIntosh custom designed
cable and is included with McIntosh Transports.
The MCT cable is part number 171923 and can be
ordered from the McIntosh Parts Department.
