Installation

The MS750 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 MS750 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 MS750 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 MS750.
Cool operation ensures the longest possible operating life
for any electronic
instrument. Do not
install the MS750
directly above a
heat generating
component such
as a high powered
amplifier. If all the
components are
installed in a single
cabinet, a quiet run­ning ventilation fan
can be a definite
asset in maintain­ing all the system
components at the
coolest possible
operating tempera­ture.

A custom
cabinet installation
should provide the
following minimum
spacing dimensions
for cool operation.

Allow at least
2 inches (5.08cm)
above the top, 2
inches (5.08cm)
below the bottom,
1 inch (2.54cm)
on each side and
2 inches (5.08cm)
behind the Music
Server, so that
airf low is not ob­structed.

Do not block the ventilation holes on the top cover,

bottom cover and rear panel. Allow 1 inch (2.54 cm) in

front of the mounting panel for clearance. When the CD
tray is opened, the panel clearance required in front of
mounting panel is 6-3/4 inches (17.2cm). Be sure to cut out
a ventilation hole in the mounting shelf according to the
dimensions in the drawing.

How to Connect the MS750

The MS750 has the ability to automatically switch On/Off
when connected to a McIntosh A/V Control Center or
Preamplifier via the Power Control Connections. The Data
Port Connections allow for the remote operation of basic
functions of the MS750 using the McIntosh A/V Control
Center or Preamplifier Remote Control. With an External
Sensor or External Touch Panel connected to the MS750,
remote control operation is possible when the MS750 is
located in a cabinet with the doors closed or from another
room.

The connection instructions below, together with the
Connection Diagram located on the separate folded sheet
“MC1A/1B”, is an example of the MS750 in a typical
audio/video system. Your system may vary from this,
however the actual components would be connected in a
similar manner. It is important to connect both the Digital
and Analog Audio connections between the MS750 and
any external disc changer as no internal conversion takes
place.

How to Operate the Setup Mode

Your McIntosh MS750 has been factory configured for
default operating settings that will allow you to immedi­ately enjoy superb audio. If you wish to make changes to
the factory default settings, a Setup feature is provided
to customize the operating settings using the On-Screen
Display (OSD) Menus.

Notes: The MS750 must be connected to a MONITOR/TV

either through an A/V Control Center or directly,
for setup and use.

The Red LED above the STANDBY/ON switch lights to

indicate the MS750 is in Standby mode. To Switch ON
the MS750, press
the STANDBY/ON
Push-button on the
Front Panel or press
the PWR(Power)
Push-button on the
Remote Control.

Notes: 1. When AC

Power is
initially applied to the MS750 the LED located above
the STANDBY/ON Push-button will flash red until
the start up process is complete and then go into the
Standby Mode. Please wait as this may take several
minutes. Refer to the separate folded sheet “MC1A/

1B” for additional start up information.

2. If power is removed from the MS750 for any reason,
including a power outage or if the unit is unplugged,
the MS750 will automatically return to the Standby
state as soon as power is restored. When it is turned
on again, the MS750 will return to the same source
mode that it was in when power was lost.

3. If the MS750 becomes unresponsive, PRESS and
HOLD the STANDBY/ON Push-button on the Front
Panel of the unit for 4 seconds, releasing when the
standby LED starts blinking.

Automatically Getting Disc Information

Once your changers are connected to the MS750 and
loaded with CDs, all you have to do is close the changer
door and in a few seconds the MS750 will begin looking
up the disc information from each disc, in each changer.

Quick Lookup checks each previously empty slot in
the changers to see if any new discs were added, and then
checks each previously occupied slot in the changer to see
if any discs were removed.

One by one, the Table of Contents is read from each CD
and compared to the Gracenote CDDB® using your Inter­net connection, as the MS750 builds your Music Library.
As each disc is accessed and looked up, the Quick Lookup
screen is updated to display the disc’s information and

cover art. When all of the discs are looked up, the Guide
screen will be displayed.

You can manually run Quick Lookup at any time by

following these steps:

1. Press the SETUP push-button on the remote to display
the Setup menu. Refer to figure 1.

2. Select the
Changer Man­agement menu.
Refer to figure 2.

3. Select the Look­up Discs menu.

4. Select the Quick
Lookup menu.

5. The MS750 will

Figure 1

perform a Quick
Lookup for each
new disc.

Warning:

Quick Lookup

checks for
newly added
and removed
CDs each time
it runs. Do not
remove CDs
and replace
new CDs
into the same
changer slots
without running
Quick Lookup
in-between, or
the MS750 will
not know that
these slots have
changed. If you
want to reuse
the same slots,
first remove
your DVD/
CDs, let Quick
Lookup run,
then add new
DVD/CDs to
the same slots.
