Installation
The MR89 can be placed upright on a table or shelf,
standing on its four feet. It also can be custom installed
in a piece of furniture or cabinet of your choice.
The four feet may be removed from the bottom of
the MR89 when it is custom installed as outlined
below. The four feet together with the mounting screws
should be retained for possible future use if the MR89
is removed from the custom installation and used free
standing. The required panel cutout, ventilation cutout
and unit dimensions are shown.
Always provide adequate ventilation for your MR89.
Cool operation ensures the longest possible operating
life for any electronic instrument. Do not install the
MR89 directly above a heat generating component such
as a high powered amplier. If all the components are
installed in a single cabinet, a quiet running ventila-
tion fan can be a denite asset in maintaining all the
system components at the coolest possible operating
temperature.
When the MR89 is placed free-standing on a at
surface, allow at least 2 inches (5.08cm) above the
top, 2 inches (5.08cm) below the bottom and 2 inches
(5.08cm) on each side of the Tuner, so airow is not
obstructed. Allow 19-1/2 inches (49.53cm) depth
behind the front panel. Allow 1-7/16 inch (3.66cm) in
front of the mounting panel for knob clearance.
A custom cabinet installation should provide the
minimum spacing dimensions for cool operation.
Allow at least 2 inches (5.08cm) above the top, 2 inches
(5.08cm) below the bottom and 2 inches (5.08cm) on
each side of the Tuner, so airow is not obstructed.
The Custom Cabinet should be open backed and at
least 12 inches (30.48cm) away from any surface such
as a wall. Be sure to cut out a ventilation hole in the
mounting shelf according to the dimensions in the
drawing. Allow 1-7/16 inch (3.66cm) in front of the
mounting panel for knob clearance.

Stereo Blend Type
When receiving low quality (weak, noisy, multipath)
FM Stereo Broadcasts, background noise can be
reduced by blending some of the left and right channel
information together, while still maintaining “The
Stereo Eect.” The MR89 provides two dierent blend-
ing types to select from, conventional Stereo Blending,
or Stereo High Blend.
Stereo Blending blends the left and right channel
information together uniformly across the audio
frequency range as signal quality decreases – blending
low and high frequencies the same amount. High
Blend blends the high frequency portion of the audio
frequency range more aggressively. The highest
frequencies are always blended and, as signal quality
decreases, more and more of the high frequencies are
aected until the eect transitions to conventional
Stereo Blending.
To select Blending Type perform the following steps:
1. Press the MONO/SETUP Push-button until the Setup
Mode is active. Then rotate the PRESET/MENU
Control to select Setup Menu item “SETUP: BLEND
TPYE.” Refer to Figure 9.

Stereo Blend Mode
The MR89 allows changes in the amount of Stereo
Separation via the Stereo Blend Function. When receiv-
ing weak FM Stereo Broadcasts any background noises
can be reduced by blending some of the left and right
channel information together, while still maintaining
“The Stereo Eect”.
To change from the Normal Setting perform the
following steps:
1. Press the MONO/SETUP Push-button until the
Setup Mode is active. Then rotate the PRESET/

3. Proceed to the next Setup Menu Item or press the
MONO/SETUP Push-button to exit the Setup Mode.
Deemphasis
The FM Transmission Standard uses Preemphasis
(boosting the volume level of the high frequencies)
of the audio signal before transmssion. Inside the
15
tuner Deemphasis (cutting the volume level of the
high frequencies) is used to return the audio signal to
the correct high frequency volume levels. The use of
Preemphasis and Deemphasis helps to reduce losses and
noises during the transmission/receive process. There are
two dierent settings for Preemphasis/Deemphasis used
today, one is 75µS (microseconds) and other is 50µS.
Your Tuner was set to the standard used in your Country.
For additional information contact your McIntosh Dealer

The MR89 Tuner provides two additional displays to
better indicate the quality of the received FM Station
Signal. These displays include Mulitpath and Noise. To
activate these two displays perform the following:
1. Press and release the Front Panel SIGNAL
Push-button. The LED above the SIGNAL
Push-button will illuminate The Front Panel
Information Display will indicate “Mpath: _ _ _ _
Noise: _ _ _ _” on the second line of the Front Panel
Information Display. Refer to gure 48.

Mpath: Noise:
Figure 48
Multipath interferance occurs when the MR89 receives
two or more signals from the Broadcast Station to which
it is tuned. The rst signal received is the direct signal
from the station and any additional signals received
occur as a result of the direct signal reected o of some
object such a building or terrain (hill/mountain). The
reected signal(s) arrives at the FM Antenna delayed
in time do to the longer travel distance incurred. This
21
delayed signal results in an increase in distortion and
a reduction in Stereo Separation. Refer to gure 49. To
reduce or eliminate Multipath, reorient the FM Antenna
for minimum indication of Multipath even if the Signal
Strength indicates less signal.

Figure 49
Noise received along with the desired FM Broadcast
Signal can occur from a variety sources, both local
and distant. If orienting the FM Antenna doesn’t either
reduce or eliminate the noise, an antenna with more gain
and directional capability might be required. Refer to
gure 50.
