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.

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.

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.
