Introduction
Introduction and Performance Features
The MR85 AM/FM Tuner is an elegant instrument that allows you to enjoy outstanding music reproduction. It includes a wide range of convenient operating functions to
enhance your listening experience. The classic McIntosh
MR85 will perfectly complement a McIntosh System of
incomparable performance and style.
Performance Features
· Special FM RF Amplifier
Double-Diffused Metal Oxide Field Effect Transistor
(DMOS-FET) RF amplifier increases sensitivity and Cross
Modulation rejection.
· External AM RF Amplifier
The MR85 includes an electrostatically shielded AM RF
Amplifier Stage with a shielded connecting cable that allows it to be located in a remote area, away from sources of
interference. The Amplifier Stage can be adjusted for optimum signal strength at both ends of the AM dial and can
be positioned for the best possible reception of even the
weakest AM stations.
· Optional Second Tuner Module
A second fully independent McIntosh TM1 Tuner Module
may be added to the MR85 by your dealer. This is ideal for
applications where two tuners may be used at the same
time, such as Multizone Systems or listening to one station
while recording another station. The TM1 is the most economical way to add a second high performance McIntosh
Tuner to a system.
· Preset Stations
Nine AM and nine FM station presets for each tuner module make it easy to listen to your favorite stations.
· Custom Preset Naming
All 9 AM and 9 FM station presets for each tuner module
may be custom labeled with any desired name up to 8 characters. For example, FM Preset Number 3 (92.50MHz) can
be renamed JAZZ 7, or WXYZ.
· Permanent Memory
Station Presets and Functions Modes are retained in Permanent Memory even when AC power is turned off.
· Flywheel Manual Tuning
A newly designed, optically encoded weighted flywheel
system makes dialing in stations an easy job. Reminiscent
of the dial-cord flywheel tuning method found in classic
McIntosh Tuners.
· FM Stereo Auto Blend Circuitry
An automatic variable stereo separation control circuit is
used to reduce background noise when receiving weak stereo stations.
· Automute
The MR85 automatically mutes when manually tuning between stations, yet provides the ability to be switched off
when searching for very weak stations.
· Spatial Sound Enhancement
A sound Spatializer circuit can be selected for Tuner 1 Enhancement. This circuit can expand the sound field for FM
stations with poor separation, or can provide a pseudo-stereo effect for AM stations.
· Alphanumeric Fluorescent Display
The Multi-function Front Panel Display indicates station
frequency, station preset number, signal strength, stereo
and broadcast band. Custom Naming for each Preset can
also be displayed. The display intensity is fully adjustable.
· Adjustable Output Level
Both Tuner 1 and the optional Tuner 2 have Variable Outputs which can be used to match audio levels between various sources.
· Remote Control Capable
When used in conjuction with a McIntosh Control Center
or Multizone Controller, tuning functions can be performed
with a remote control.
· Special Power Supply
Fully regulated power supply with double shielded power
transformer ensures stable noise free operation even if the
power line should vary.
