Performance Features
Introduction and Performance Features
Introduction
The MR85 AM/FM Tuner is an elegant instrument that al-
lows you to enjoy outstanding music reproduction. t in-
cludes a wide range of convenient operating functions to
enhance your listening experience. The classic Mc ntosh
MR85 will perfectly complement a Mc ntosh System of
incomparable performance and style.
·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 al-
lows it to be located in a remote area, away from sources of
interference. The Amplifier Stage can be adjusted for opti-
mum signal strength at both ends of the AM dial and can
be positioned for the best possible reception of even the
weakest AM stations.
·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
Mc ntosh Tuners.
·FM Stereo Auto Blend ircuitry
An automatic variable stereo separation control circuit is
used to reduce background noise when receiving weak ste-
reo stations.
·Automute
The MR85 automatically mutes when manually tuning be-
tween 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 En-
hancement. This circuit can expand the sound field for FM
stations with poor separation, or can provide a pseudo-ste-
reo effect for AM stations.
·Optional Second Tuner Module
A second fully independent Mc ntosh 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 eco-
nomical way to add a second high performance Mc ntosh
Tuner to a system.
·Preset Stations
Nine AM and nine FM station presets for each tuner mod-
ule make it easy to listen to your favorite stations.
·ustom 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 char-
acters. 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 Perma-
nent Memory even when AC power is turned off.
·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 Out-
puts which can be used to match audio levels between vari-
ous sources.
·Remote ontrol apable
When used in conjuction with a Mc ntosh 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.

Installation
The MR85 can be placed upright on a table or shelf, stand-
ing on its four feet. t also can be custom installed in a
piece of furniture or cabinet of your choice. The required
panel cutout, ventilation cutout and unit dimensions are
shown.
Always provide adequate ventilation for your MR85.
Cool operation ensures the longest possible operating life
for any electronic instrument. Do not install the MR85 di-
rectly above a heat generating component such as a high
powered amplifier. f all the components are installed in a
single cabinet, a quiet running ventilation fan can be a defi-
nite asset in main-
taining all the sys-
tem components
at the coolest pos-
sible operating
temperature.
A custom cabi-
net installation
should provide the
following mini-
mum spacing di-
mensions for cool
operation. Allow
at least 2 inches
(5.08 cm) above
the top, 2 inches
(5.08cm) below
the bottom and 1
inch (2.54 cm) on
each side of the
AM/FM Tuner, so
that airflow is not
obstructed. Allow
20 inches (50.8
cm) depth behind
the front panel.
Allow 1 inch
(2.54 cm) in front
of the mounting
panel for knob
clearance. Be sure
to cut out a venti-
lation hole in the
mounting shelf
according to the
dimensions in the
drawing.
