A newly designed, optically encoded weighted flywheel  
system makes ‘dialing in’ stations a breeze. Reminiscent of  
the dial-cord flywheel tuning method found in classic  
McIntosh Tuners. 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  
An automatic variable stereo separation control circuit is  
used to reduce background noise when receiving weak ste-  
reo stations. A sound Spatializer circuit can be selected for  
Tuner 1 Enhancement. This circuit can expand the sound  
field for FM stations with poor separation; it also provides  
a pseudo-stereo effect for AM stations.

The McIntosh MR85 is an advanced design AM/FM Tuner  
with many desirable performance features to enhance your  
enjoyment of radio broadcasts. There are three modes of  
tuning to an AM/FM Broadcast Station. There is Manual  
Tuning using the TUNING Knob; Seek Mode Station Se-  
lection using the SEEK S (Up) and T (Down) Push-  
button(s); and Preset Station Selection using the PRESET  
Selection Knob.  
Figure 2  
Manual Tuning  
Manual Tuning is provided through the Front Panel TUN-  
ING Knob. Rotate the TUNING Knob clockwise to tune up  
in frequency, 10kHz steps for AM or 200kHz steps for FM.  
Spin the knob to tune up continuously. Rotate the TUNING  
Knob counterclockwise in the same manner to tune down  
in frequency. When a station is selected, the Front Panel  
Display will indicate (from left to right) a Preset Number,  
if that station has been assigned a Preset, the FM Station  
Frequency, the received Stations Signal Strength from 1 to  
9, and a dot (located to the right of the Signal Strength  
Digit) if the station is broadcasting stereo.  
Note: When the MR85 AM/FM Tuner is connected to a  
McIntosh Control Center, A/V Multizone System  
Controller or Preamplifier via a data connection ,the  
tuner functions such as SEEK, direct PRESET Selection  
and REVIEW of Preset Stations may be controlled by  
the McIntosh Remote Control and/or Keypad.  
Preset Selector Switch  
Note: FM band indications are in Megahertz. In the US and  
Canada, they change frequency in 200kHz steps. The  
second digit to the right of the dot which displays a 0, is  
used for FM stations in Europe where stations change  
in 50kHz steps. In Europe and Japan, the AM display  
changes in 9kHz steps.  
The PRESET Selection Switch allows selection of desired  
radio stations that have already been stored into memory.  
There are up to 9 AM and 9 FM stations that can be stored  
for the Tuner 1. The optional secondary Tuner 2 Module  
also has up to 9 AM and 9 FM stations that can be stored  
Figure 1

either an AM or FM signal. For example, AM Stations with  
monaural signals will have a simulated stereo effect. The  
LED above the SPATIAL Push-button will light when in  
the Spatial Mode.  
Automute Function  
When manually tuning through the band, the outputs will  
unmute only when a strong radio station is sensed and re-  
ceived. Sometimes it is desirable to search for a very weak  
station and the AUTOMUTE Function can be switched  
OFF. This will allow all stations to be heard as well as  
noise and interference normally found in-between stations.  
The LED above the AUTOMUTE Push-button will light  
when the Automute Function is active.  
Note: The Spatial Enhancement function is for the Tuner 1  
only.  
Note: The AUTOMUTE Function can only be switched OFF  
when manually tuning to a station using the TUNING  
Knob. When using SEEK S (Up) and T (Down) Push-  
button(s), the AUTOMUTE Function will always be  
engaged.  
Mono Mode  
Press the MONO Push-button to combine left and right ste-  
reo signals to monaural. This is useful when the MR85  
Tuner is receiving a very weak Stereo Signal that might be  
accompanied with a high degree of background noise. By  
switching to MONO Mode, most of the background noise  
will disappear, thus making the station more listenable. The  
LED above the MONO Push-button will light when in the  
MONO Mode.  
Output Level Control (Rear Panel)  
There are both FIXED OUTPUTS and VARIABLE OUT-  
PUTS on the MR85 Rear Panel for Tuner 1 and optional  
secondary Tuner 2 Module. For most applications, the vol-  
ume level at the FIXED OUTPUTS will match other  
sources connected to the McIntosh Control Center or  
Preamplifier. If the volume level from the tuner is higher  
than from other sources, the VARIABLE OUTPUTS to-  
gether with the OUTPUT LEVEL Control may be used to  
reduce the tuner volume level.  
Note: When the tuned to an AM Radio Station the tuner will  
automatically switch to the MONO Mode.  
Tuner Selector  
The Tuner Selector selects between the default Tuner 1 and  
the optional secondary Tuner 2 Module, if installed. Once  
the desired tuner is selected, the Front Panel Controls in-  
cluding Station Selection and Preset Assignment may be  
performed. The Number 1 LED above the TUNER Push-  
button will light, indicating when Tuner 1 has been se-  
lected and the Number 2 LED above the TUNER Push-but-  
ton will light when Tuner 2 Module is selected.  
Reset of Microprocessor  
In the event that the controls of the MR85 stop functioning,  
there is a built-in user reset function. Press the POWER  
switch to the OFF position and wait for two minutes. Then  
press the POWER switch to ON; the Red LED above the  
STANDBY/ON Push-button, lights to indicate the MR85 is
