The Mclntosh MR 7083 is a high quality AM/FM

Tuner whose design has been governed by insistence
on high performance with long life, great flexibility

and sensitivity.

You will derive the greatest enjoyment and most

satisfaction from your MR 7083 when you understand

its operations and functions. Your time invested now

will return added value to you because you will get
the best results from your MR 7083.

Mclntosh has earned world renown for its techno-

logical contributions for improved sound. When you
bought Mclntosh, you bought not only high techno-
logy, you bought technological integrity proven by

time. The Mclntosh MR 7083 Tuner is continuing
evidence of Mclntosh technological superiority and

integrity.

Music reproducing instruments that carry the

Mclntosh name have always been designed for

technological leadership and to maintain the

Mclntosh reputation for durability, long life, and best
sound. Mclntosh has had to earn the foremost

reputation for quality performance. Mclntosh has

provided user-oriented facilities and appearance, and

Mclntosh design provides for ease of maintenance or

repair. These fundamental elements are incorporated

in the Mclntosh MR 7083 AM/FM Tuner, the easiest

to operate yet with extensive useful features.

Your Mclntosh MR 7083, above all others, will

deliver the best sound and the greatest ease of use

with a high degree of flexibility.

Some of the features that set the MR 7083 apart

from the ordinary are:

The advanced AM/FM tuner design of the MR 7083

displays the station frequencies digitally. Stations are
selected easily in any one of these ways: A. use the

manual tuning knob, B. use the SCAN up or down

touchbuttons, C. use the preset station touchbuttons

or, D. use the SEARCH which will preview the preset
stations for 5 seconds each.

The sound enhancing SPATIAL audio processor

provides an aural picture that is more "stereo like"
in quality and dimension. On noisy, weak FM sta-

tions or AM stations, SPATIAL provides reduced

noise and retains a broad stereo-like sound.

High quality tape recordings of FM broadcasts can

be made without the interference that stereo trans-
missions can cause. Carefully designed suppression

circuits eliminate the potential for stereo carrier

noise when making "off the air" tape recordings.

A unique Phase Locked Loop Multiplex decoder

delivers STEREO FM with lower distortion, lower

noise, and better separation.

The most useful and flexible AM antenna system

will suit your particular installation. A low-impedance

loopstick will, in most local areas, provide AM

signals while rejecting noise and interference. In

noisy AM locations, an external noise reducing, noise

canceling, shielded loop will provide ideal input
signal. In a remote location, a conventional 'long

wire' antenna can be used.

The MR 7083 can be remote controlled from a

Mclntosh IR Remote Control system.

All in all, your selection of the MR 7083 will be

reinforced by your day-to-day use of this superb
instrument. Good listening.
