Phono Preamplifier: The MP100 is the first dedicated phono preamplifier from McIntosh. Designed to
help both new and experienced vinyl lovers get the most fidelity, performance,
and enjoyment from their albums. Its a great choice for someone new to vinyl, for someone with an older home audio
system wanting to add modern phono capabilities, or for someone looking to add
phono playback to a home theater system.
Moving Coil (MC) & Moving Magnet (MM) Inputs: The MP100 has two precision phono
preamplifier circuits, one for Moving Coil (MC) Phono Cartridges and the other
for Moving Magnet (MM) Cartridges. Both phono inputs have selectable loading.
The circuits use the latest designs providing the lowest possible noise and
distortion. The close tolerance resistors and capacitors used in the RIAA
Correction Equalization Circuitry provides an extremely flat frequency response.
- MM Load (PF) Setting: The MM LOAD (PF) Control with indicators is
used to select the capacitive value in picofarads added to the input signal
path for a flat frequency response from the connected Moving Magnet phono
cartridge. Set to 50, 100, 150, 200, 300, or 400 picofarads.
- MC Load (Ohms) Setting: The MC LOAD (OHMS) Control with
indicators is used to select the resistive value in ohms added to the input
signal path for a flat frequency response from the connected Moving Coil
phono cartridge. Set 25, 50, 100, 200, 400, or 1k Ohms.
Balanced & Unbalanced Outputs: The balanced XLR outputs allow the
connection using long cable lengths without a loss in sound quality. The MP100
also has unbalanced RCA output connections for compatibility with a wide range
of audio components.
Note: The balanced and unbalanced outputs may be used simultaneously and
connected to different preamplifiers or component recording devices.
24-Bit/96kHz Analog-to-Digital Converter: The MP100's
internal analog-to-digital converter circuitry is designed to encode 2-channel
PCM (Pulse Code Modulation) digital audio signals. The digital outputs (Optical,
Coaxial, & USB-B) are fixed at 24-bit/96kHz to capture the full dynamic range of
a record while optimizing digital file size.
Note: The phono preamp's digital circuitry can be switched off, providing a true analog only signal
Optical & Coaxial Digital Outputs: The McIntosh MP100 is
fitted with one optical (toslink) digital output & one coaxial (RCA) digital
output. The digital outputs encode 2ch PCM Signals from the selected Phono
input. The optical & coaxial outputs process digital audio signals at 96kHz with
24-Bit resolution. The digital outputs have two different output levels settings
- Low or High.
USB-B Port For "Ripping": The McIntosh MP100 is equipped with a
USB-B port for connecting the phono preamp to your computer. When used with a properly configured conversion program, the MP100 can "rip"
your vinyl records to a computer via USB to produce high quality digital music
files. The USB-B port provides digital audio signals at 96kHz with 24-Bit
resolution from the selected Phono input.
Note: The MP100's USB-B output is compatible with Windows PC (7/8.1/10)
and Mac (OS 10.6.8 or later). When using a Windows PC, a special
McIntosh USB Audio Software Driver will need to be installed on the
Clipping Indicator: If an album has a very
loud section, the clipping indicator will alert you so you can lower the digital
output in order to produce a distortion-free recording.
Mono Button: The Mono button combines the left and right channel
signals for a monophonic sound.
Electromagnetic Input Switching: Digital Logic Circuits drive
electromagnetic switches on inputs and operating functions for reliable,
noiseless, distortion free switching.
Power Control Connections: The Power Control connections (3.5mm
Trigger In/3.5mm Trigger Out) provide convenient Turn-On/Off synced operation
with other McIntosh audio components.
Multi-Regulated Power Supply: The multi-regulated power
supply ensures stable noise free operation even though the power line varies.
LED Front Panel Illumination: The even Illumination of
the front panel is accomplished by multiple extra long life Light Emitting
Diodes (LEDs) arranged with a special orientation.
Glass Front Panel & Stainless Steel Chassis: The famous
McIntosh illuminated glass front panel and the stainless steel chassis with
super mirror finish ensures the pristine beauty of the MP100 will be retained
for many years.
Mounting Options: The MP100 Phono Preamplifier is designed to be
placed upright on a table or shelf, standing on its feet. Do not install the
MP100 directly above a heat generating device, such as a power amplifier. Allow
at least 1" above the top, 7/8"below the bottom and 1" on each side of the
MP100, so that airflow is not obstructed. Allow 16.75" of depth for airflow and
Auto Off Feature: The MP100
incorporates an Auto Off Feature, which automatically places the phono
preamplifier into the Power Saving Standby/Off Mode. This occurs approximately
30 minutes after there has been an absence of an audio signal & user activity.
