The MP1100 Vacuum Tube
Phono Preamplifier will give vinyl lovers a new level of musical enjoyment and
exhilaration. It’s filled to the brim with everything you need to not only play
new records or pressings from the early days of vinyl, but it will also get
every last musical note and nuance out of them – including some you may have
never heard before.
"Phono stages: I dream about them, but I
never had a dream like this. The new MP1100 phono stage from McIntosh is quite
unlike anything that would pop into my head in the middle of the night, but
McIntosh does a lot of things differently – and also very well. Their new
MP1100 phono stage... is both fascinating and impressive... a phono stage that
has it all." -Hi-Fi World
The MP1100 is designed first and foremost for
analog audio and achieves our most accurate equalization ever. It utilizes four
12AX7A vacuum tubes, with 2 tubes used per channel in a fully balanced
configuration – making it our very first fully balanced vacuum tube phono
stage. For those with multiple turntables or tonearms, there are 3 sets of RCA
phono inputs; XLR connectors are also available on 1 of the inputs. All phono
inputs allow for adjusting both resistance (7 settings) and capacitance (8
settings). For ease of use, it comes pre-programmed with profiles for Moving
Coil and Moving Magnet cartridges as well as the McIntosh MT10 and MT5 turntables. Five additional profiles
are included that are fully customizable and can be assigned to any phono
input. RIAA, LP, NAB, AES and 78 analog equalization curves are included.
The MP1100 exhibits "an absolute accuracy
in the timbre," making it sound very close to the real instrument. Winner
of Top Quality Award. - Fedeltà del Suono
Two fairly rare but highly useful analog
filters are built-in: a Rumble Filter helps remove noise that may have seeped
into a song during the recording process; while a Scratch Filter can help
restore the sound of frequently-played records that may have become a little
worn, or records that may have some damage. Adjustable gain from 40dB to 64dB
allows for further customization, while a Mono setting permits proper playback
of mono recordings. In addition, there’s a pair each of balanced and unbalanced
high level inputs for connecting other sources. For connecting to the rest of
your audio system, there are a pair each of balanced and unbalanced stereo
outputs.
"It’s one of a kind... very easy to use
and to configure... from an acoustic point of view... [it] is the best phono
preamplifier" from McIntosh. - Suono
Not to completely overlook the merits of
digital audio, the MP1100 has an optical, coaxial and USB output. These digital
outputs are fixed at 24-bits and can be set to either 96kHz or 192kHz. When
used with a properly configured conversion program, the USB output can be used
to “rip” your albums to your computer. Our digital output clipping indicator
will notify you when distortion caused by loud sections in a song is being
recorded to the file, allowing you to adjust your settings in order to create
pristine, distortion free digital versions of your albums. For pure analog use,
the digital outputs can be completely disabled and powered down.
To combat noise, the MP1100 features a dual
mono design with the left and right audio channels electrically and
mechanically isolated from each other while the power supplies are
electronically separated. It can be paired with any preamplifier, integrated
amplifier or home
theater processor that
includes volume control. An ideal match is our C1100
Vacuum Tube Preamplifier which
also has a dual mono design; both also share the same polished stainless steel
and hairline brushed black Titanium stainless steel chassis to create a
cohesive appearance. Classic McIntosh design cues complete the MP1100. Contact
