Introduction and Performance Features

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 complement 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

The MR85 includes an electrostatically shielded AM RF Amplifier Stage with a shielded connecting cable that al- lows it to be located in a remote area, away from sources of interference. The Amplifier Stage can be adjusted for opti- mum signal strength at both ends of the AM dial and can be positioned for the best possible reception of even the weakest AM stations.

·Flywheel Manual Tuning

A newly designed, optically encoded weighted flywheel system makes ‘dialing in’ stations an easy job. Reminiscent of the dial-cord flywheel tuning method found in classic McIntosh Tuners.

·FM Stereo Auto Blend Circuitry

An automatic variable stereo separation control circuit is used to reduce background noise when receiving weak ste- reo stations.

·Automute

The MR85 automatically mutes when manually tuning be- tween stations, yet provides the ability to be switched off when searching for very weak stations.

·Spatial Sound Enhancement

A sound Spatializer circuit can be selected for Tuner 1 En- hancement. This circuit can expand the sound field for FM stations with poor separation, or can provide a pseudo-ste- reo effect for AM stations.

·Optional Second Tuner Module

A second fully independent McIntosh TM1 Tuner Module may be added to the MR85 by your dealer. This is ideal for applications where two tuners may be used at the same time, such as Multizone Systems or listening to one station while recording another station. The TM1 is the most eco- nomical way to add a second high performance McIntosh Tuner to a system.

·Preset Stations

Nine AM and nine FM station presets for each tuner mod- ule make it easy to listen to your favorite stations.

·Custom Preset Naming

All 9 AM and 9 FM station presets for each tuner module may be custom labeled with any desired name up to 8 char- acters. For example, FM Preset Number 3 (92.50MHz) can be renamed “JAZZ 7”, or “WXYZ”.

·Permanent Memory

Station Presets and Functions Modes are retained in Perma- nent Memory even when AC power is turned off.

·Alphanumeric Fluorescent Display

The Multi-function Front Panel Display indicates station frequency, station preset number, signal strength, stereo and broadcast band. Custom Naming for each Preset can also be displayed. The display intensity is fully adjustable.

·Adjustable Output Level

Both Tuner 1 and the optional Tuner 2 have Variable Out- puts which can be used to match audio levels between vari- ous sources.

·Remote Control Capable

When used in conjuction with a McIntosh Control Center or Multizone Controller, tuning functions can be performed with a remote control.

·Special Power Supply

Fully regulated power supply with double shielded power transformer ensures stable noise free operation even if the power line should vary.
