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 S and T

Press and release the Front Panel SEEK S (Up) and T (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 S (Up) and T (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 STANDBY/ON Push-button, lights to indicate the MR85 is
