How to Operate

Enter Mode

The ENTER Push-button is used to enter into memory, de-

sired AM or FM radio stations and any custom naming you

might wish. A station Preset and its custom name may also

be cleared from memory using the ENTER Push-button.

The LED above the ENTER Push-button will light when in

the Preset Enter Mode.

Display Modes

The DISPLAY Push-button allows for adjustment of the

Front Panel Alphanumeric Display Brightness from Off (0)

to Bright (31) and for Custom Naming Station Presets with

the name of your choice. Refer to figure 3.

Spatial Enhancement

Press the Spatial push-button to add Audio Enhancement to

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.

Note: The Spatial Enhancement function is for the Tuner 1

only.

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.

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.

Note: If the optional secondary Tuner 2 Module is not

installed, the TUNER Selector will stay on the TUNER 1

selection.

AM/FM Band Selector

Select the AM or FM Broadcast Band by pressing the AM/

FM push-button.

Note: When the Front Panel Alphanumeric Display is

displaying the radio station frequency (default), the

letters AM or FM will appear to the right of the tuned

stations frequency to indicate the broadcast band.

SEEK p and q

Press and release the Front Panel SEEK p (Up) and q

(Down) Push-button(s), to move from one station to the

next. Press and hold the SEEK Push-button to move

continuously up or down the broadcast band.

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 AUTOMUTE Function can only be switched OFF

when manually tuning to a station using the TUNING

Knob. When using SEEK p (Up) and q (Down) Push-

button(s), the AUTOMUTE Function will always be

engaged.

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.

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
