General:
1. Read all the safety and operating instructions, contained in this owners manual, before operating this
equipment.
2. Retain this owners manual for future reference about
safety and operating instructions.
3. Adhere to all warnings and operating instructions.
4. Follow all operating and use instructions.
5. Warning: To reduce risk of fire or electrical shock,
do not expose this equipment to rain or moisture.
This unit is capable of producing high sound pressure levels. Continued exposure to high sound pressure levels can cause permanent hearing impairment or loss. User caution is advised and ear protection is recommended when playing at high volumes.
6. Caution: to prevent electrical shock do not use this
(polarized) plug with an extension cord, receptacle
.
or other outlet unless the blades can be fully inserted to prevent blade exposure.
Attention: pour pevenir les chocs elecriques pas
utiliser cette fiche polarisee avec un prolongateur,
une prise de courant ou un autre sortie de courant,
sauf si les lames peuvent etre inserees afond ans en
laisser aucune partie a decouvert.
7. For added protection for this product during a lightning
storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet. This
will prevent damage to the product due to lightning or
power line surges.
8. Do not use attachments not recommended in this
owners manual as they may cause hazards.
Installation:
9. Locate the equipment for proper ventilation. For example, the equipment should not be placed on a bed,
sofa, rug, or similar surface that may block ventilation
openings; or, placed in a built-in installation, such as a
bookcase or cabinet, that may impede the flow of air
through the ventilation openings.
10. Locate the equipment away from heat sources such as
radiators, heat registers, stoves, or other appliance(s)
(including amplifiers) that produce heat.
11. Mount the equipment in a wall or cabinet only as described in this owners manual.
12. Do not use this equipment near water; for example,
near a bathtub, washbowl, kitchen sink, laundry tub, in
a wet basement or near a swimming pool, etc.
13. Do not place this product on an unstable cart, stand,
tripod, bracket, or table. The equipment may fall, causing serious injury to a person, and serious damage to
the product.
Connection:
14. Connect this equipment only to the type of AC power
source as marked on the unit.
15. Route AC power cords so that they are not likely to be
walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit
from the instrument.
16. Do not defeat the inherent design features of the polarized plug. Non-polarized line cord adapters will defeat
the safety provided by the polarized AC plug. If the
plug should fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety
purpose of the grounding-type plug.

Introduction
The McIntosh MSE1 is a precision Surround Expander
which will reproduce the back channels of specially encoded 5.1 digital sound tracks with ultimate fidelity and
sonic purity. The MSE1 has many valuable and useful features that will enhance your home theater listening experience.
Performance Features
· 24 Bit DSP Processing
The Motorola 24 Bit Digital Signal Processors decode the
back channel information from specially encoded Digital
5.1 sound tracks.
· 20 Bit Conversion
Two 20 bit stereo digital to analog, (D/A) converters are
used to reproduce the back channel information, and one
20 bit stereo analog to digital, (A/D) converter is for input
signal from the analog inputs.
· Automatic Expansion Mode
The MSE1 automatically switches expansion modes when
receiving specially encoded Digital 5.1 sound tracks (requires connections to the McIntosh MX132 A/V Control
Center). Expand nomenclature illuminates to show which
decoding mode is in use.
· LED Output Format / Delay / Volume Indicators
The MSE1 includes four LEDs on the Front Panel to indicate status of the output signal format. In addition, there is
a two digit LED indicator that shows the Trim Volume,
Time Delay and Channel Level during surround level calibration.
· Adjustable Channel Time Delays
Signals to the back Surround channels can be time delayed.
This feature can be used to correct the different listening
distances from the back surround speaker(s) and the primary listening location.
· Built-In System Level Calibration Generator
A built-in test signal generator can be switched manually or
automatically through all surround channels for surround
level calibration. The levels can be adjusted plus or minus
6dB.
· Automatic Input Level Control
The Analog Input includes a special circuit which protects
against accidental input signal overdrive.

Installation
The MSE1 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 required
panel cutout, ventilation cutout and unit dimensions are
shown.
Always provide adequate ventilation for your MSE1.
Cool operation ensures the longest possible operating life
for any electronic instrument. Do not install the MSE1 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 (5.08 cm)
above the top, 2
inches (5.08cm) below the bottom and
1 inch (2.54 cm) on
each side of the
Surround Expander,
so that airflow is
not obstructed. Allow 20 inches (50.8
cm) depth behind
the front panel. Allow 1 inch (2.54
cm) in front of the
mounting panel for
clearance. Be sure
to cut out a ventilation hole in the
mounting shelf according to the dimensions in the
drawing.

How to Connect with a MX132
The following connection instructions and illustrations
cover the addition of the McIntosh MSE1 Surround Expander, McIntosh Back Surround Power Amplifier and optional secondary McIntosh Power Subwoofer into an existing MX132 Home Theater System. For additional connection information, please refer to the owners manuals for
the particular components that make up your system.
1. Connect a Power Control Cable from the MX132
Power Control A jack to the POWER CONTROL IN
jack of the McIntosh MSE1 Surround Expander.
2. Connect a Power Control Cable from the POWER
CONTROL OUT jack of the McIntosh MSE1 Surround Expander to the Power Control In jack of the
McIntosh Back Surround Power Amplifier.
3. Connect a Power Control Cable from the Power Control Out jack of the McIntosh Five Channel Power Amplifier to the Power Control In jack of the McIntosh
Powered Subwoofer.
4. Connect a Data cable from the MX132 Sum A Data Out
Port to the DATA IN of a jack of the McIntosh MSE1
Surround Expander.
5. Connect cables from the MX132 Zone A Surround Outputs to the ANALOG Inputs of the McIntosh MSE1
Surround Expander.
6. Temporarily disconnect the male end of the 25 conductor DB25 cable from the McIntosh Five Channel
Power Amplifier. Locate and remove (cut out) pins 5,
6, 18 and 19 from the male connector end of the DB25
cable. Reconnect the now modified male end of the
DB25 cable to the McIntosh Five Channel Power Amplifier.
Note: The above step is necessary, as the Left and Right
Surround Channels receive additional sound processing
in the MSE1 Surround Expander. The next step connects
the MSE1 Surround Outputs to the McIntosh Five
Channel Power Amplifier using the audio connection
cables. If your system consists of
a McIntosh Six Channel Power
Amplifier the same above step
must also be performed.

7. Connect cables from the McIntosh
MSE1 Surround Expander
SURRound Outputs to the Surround Inputs of the McIntosh Five
Channel Power Amplifier.
8. Connect cables from the McIntosh
MSE1 Surround Expander
BACK2 Outputs to the Inputs of
the McIntosh Surround Power
Amplifier.
Note: The MSE1 also has a BACK1 Output that provides a
single Surround Back Channel that may be used in
place of the BACK2 Output.
9. Connect the loudspeaker hookup cables to the output
terminals of the McIntosh Surround Power Amplifier.
10. Plug the MSE1 AC power cord into a live AC outlet.
