Introduction

The MR85 AM/FM Tuner is an elegant instrument that al- lows you to enjoy outstanding music reproduction. It in- cludes a wide range of convenient operating functions to enhance your listening experience. The classic McIntosh MR85 will perfectly compliment a McIntosh System of incomparable performance and style.

Performance Features

•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 and Antenna

The included RAA1 Remote AM Antenna contains an elec- trostatically shielded AM RF Amplifier Stage and can be located in a remote area away from sources of interference

assuring the best possible reception.

•Flywheel Manual Tuning and Automute

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.

•FM Stereo Auto Blend Circuitry and

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.

•Optional Second Tuner Module

The McIntosh TM1 Tuner Module may be added to the MR85 by your Dealer and is the most economical way to add a second tuner to a system. This is ideal for applica- tions where two tuners may be used at the same time, such as Multizone Systems or listening to one station while re- cording another station.

•Preset Stations and Custom Preset Naming

Nine AM and nine FM station presets with custom naming (any desired name may contain up to eight characters) for each tuner module make it easy to listen to your favorite stations. For example, FM Preset Number 3 (92.50MHz) can be renamed “JAZZ 7”, or “WXYZ”. The station pre- sets, custom naming and functions modes are retained in Permanent Memory even when AC power is turned off.

•Alphanumeric Fluorescent Display

The Multifunction Front Panel Display indicates station frequency, station preset number, custom naming, signal strength, stereo and broadcast band. The display intensity is fully adjustable.

•Adjustable Output Level and Remote Control

Capable

Both Tuner 1 and the optional Tuner 2 have Variable Out- puts which can be used to match audio levels between vari- ous sources. When used in conjunction with a McIntosh Control Center or Multizone Controller, tuning functions can be performed with a remote control.
