The D1100 digital preamplifier is a reference level stereo
preamplifier and digital-to-analog converter (DAC). Its 8-channel,
32-bit DAC is used in Quad Balanced mode with half of it dedicated to
the left audio channel and the other half to the right channel. It’s the
most advanced DAC we’ve ever used and delivers an unprecedented level
of performance so that all your digital music is reproduced with
exceptional accuracy and authenticity.

Enough inputs – 9 to be exact – are included to keep even the largest
digital system connected as 3 optical, 3 coaxial (2 RCA and 1 BNC),
plus 1 each of MCT, AES/EBU and USB inputs are onboard. The USB input
accepts up to 32-bit/384kHz signals and supports DSD64, DSD128, DSD256,
DXD 352.8kHz and DXD 384kHz playback1. All the other inputs
accept up to 24-bit/192kHz. The MCT input is a McIntosh exclusive and
allows for enjoying to the high resolution audio found on SACDs via the MCT450 SACD/CD Transport.
Three sets of balanced and unbalanced stereo outputs connect the D1100
to your system. One set of outputs has fixed volume while the other 2
have variable volume; the variable outputs can also be switched on and
off for additional user configurability.

The D1100 is designed for ease of use: all inputs can be renamed; its
4 data ports and 4 power control triggers are fully programmable; and
it has both IR and RS232 external control. For personal listening,
Headphone Crossfeed Director (HXD®) will bring a new depth and spatiality to your music.
