on McIntosh Power Amplifiers. A 3.5mm stereo mini
phone plug is used for connection to the Power Con-
trol, Trigger and Passthru Outputs.
Data Port Connectors
The Data Out Ports send Remote
Control Signals to Source Compo-
nents. A 3.5mm stereo mini phone
plug is used for connection.
IR IN Port Connectors
The IR IN Port also uses a 3.5mm
stereo mini phone plug and allows the
connection of other brand IR Receiv-
ers to the MA9000.
RS232-C Data Port Cable
The RS232 Data Cable is a 3.5mm stereo mini phone
plug to a sub miniature DB 9 connector:
Output Terminal Connector
When cables with spade lugs are used
for Loudspeaker Connection, the spade
lugs need an opening of at least 3/10 inch
(7.6mm)
McIntosh Plug-In Jumper Connector
The MA9000 utilizes two phono style Plug-In Jump-
ers to connect the Preamplifier Output to
the Power Amplifier Input. Note: The Jumper Connector is available from the McIntosh Parts Department:
McIntosh Jumper Connector Part No. 117781
XLR Connectors
Below is the Pin configuration for the XLR Balanced
Connectors on the MA9000. Refer to the diagram for
connection:
PIN 1: Shield/Ground
PIN 2: + Output
PIN 3: - Output
Power Control and Trigger Connectors
The Power Control Trigger Output Jacks send and
Passthru Input Jack receives Power
On/Off Signals (+12 volt/0 volt)
when connected to other McIntosh
Components. An additional connec-
tion is for controlling the illumina-
tion of the Power Output Meters
1. For additional connection information, refer to the
owners manual(s) for any component(s) connected
to the MA9000.
2. Apply AC Power to the MA9000 and other McIn- tosh Components only after all the system compo-
nents are connected together. Failure to do so may
cause a malfunction of system operations as the
Microprocessors Circuitry inside the components
is active when AC Power is applied.
3. The MA9000 includes an Power Mode Auto Off
Feature and the default setting is enabled. For
additional information including how to disable it,
refer to page 22.
4. When Power Amplifier Protection Circuitry of the MA9000 has activated, the Front Panel Power
Guard LEDs are illuminated continuously and the
sound will be muted.
5. When the Power Transformer has overheated due to improper ventilation and/or high ambient operat-
ing temperature, AC Power is removed from the
MA9000. Normal operation will resume when the
operating temperature is in a safe range again.
6. For the best performance and safety, it is important to always match the impedance of the Loudspeaker
to the Power Amplifier connections. Refer to pages
11 and 12.
Note: The impedance of a Loudspeaker actually var ies as the Loudspeaker reproduces different
frequencies. As a result, the nominal impedance
rating of the Loudspeaker (usually measured at
a midrange frequency) might not always agree
with the impedance of the Loudspeaker at low
frequencies where the greatest amount of power
is required. Contact the Loudspeaker Manufac
turer for additional information about the actual
impedance of the Loudspeaker before connecting
it to the McIntosh MA9000.
7. The MA9000 Remote Control is capable of operat-ing other components. For additional information
go to www.mcintoshlabs.com.
8. The IR Input, with a 1/8 inch mini phone jack, is configured for non-McIntosh IR sensors such as
a Xantech Model DL85K Kit. Use a Connection
Block such as a Xantech Model ZC21 when two
or more IR sensors need to be connected to the
MA9000. The signal from a connected External
IR Sensor will have priority over the signal from
the Front Panel IR Sensor.
9. When discarding the unit, comply with local rules or regulations. Batteries should never be
thrown away or incinerated but disposed
of in accordance with the local regula-
tions concerning battery disposal.

Your McIntosh MA9000 has been factory configured
to allow immediate enjoyment of superb audio with-
out the need for further adjustments. If you wish to
make changes to the factory default settings, a Setup
Feature is provided to customize the operating settings

MA9000 Front Panel Illustration on the previous page
while performing the following steps.
Note: If the MA9000 is currently On, proceed to
step 2.
1. Press the STANDBY/ON Push-button on the Front Panel or press the (Power ON) Push-button on
the Remote Control to switch On the MA9000.
The MA9000 will go through a brief startup
initialization with the Front Panel Information
Display first indicating MA9000, followed by
the last used source and volume setting. This is
followed by the volume setting indication starting
at zero and then increasing to the last used volume
setting. Refer to figure 1.
2. Press and hold in the INPUT Control until the Front Panel Information Display indicates
MA9000 V1.00, (or higher Main Firmware ver-
sion) - S/N: AFK (Serial Number). Refer
to figure 2.
3. Rotate the INPUT Control to select the Setup Mode Menu item, SETUP: Inputs, (Hold IN-
PUT). Continue to rotate the INPUT CON-
T R O L t o v i e w t h e o t h e r S E T U P M o d e O p t i o n s . Refer to figure 3.
4. To exit from the SETUP Mode, press and hold in the INPUT Control and the Front Panel Display
will indicate its normal display. Refer to figure 1.
The MA9000 functionality is controlled by internal
software that is know as Firmware. There are two
Firmware Identification Numbers for the MA9000.
The first Firmware Number is for the Main Circuitry
of the MA9000 and can be identified at any time by How to Operate the Setup Mode

The MA9000 provides the ability to switch unused
INPUTS Off (or back On if they have been previously
switched Off ). The default INPUT Names can be
changed to match the name of the component con-
nected to it or any other custom name desired (within
10 Characters).
I NPUT SWITCHED ON/OFF:
In the following example, the UNBAL 4 Input will be
switched Off.
Note: When an INPUT is swiched Off, its name will
no longer appear on the Front Panel Informa
tion Display when using the INPUT Control
(Front Panel or Remote Control).
1. Press and hold in the INPUT Control to enter the SETUP MODE. Refer to figure 2. Input Settings utilizing the Setup Mode.1. Press and hold in the INPUT Control to enter Setup Mode.
2. Referring to the Front Panel Information Display- the number after the character V is the Firm-
ware number. Refer to figure 2.
To view the second Firmware Number, which is for
the Digital Audio Circuitry of the MA9000, perform
the following steps: 3. Press and hold in the INPUT Control to enter Setup Mode.
4. Rotate the INPUT Control until the Front Panel Information Display indicates DA1 Firmware,
V1.00 (or higher Digital Audio Firmware ver-
sion). Refer to figure 4.
5. To exit the Setup Mode, press the INPUT Control.

When the MA9000 is part of a Home Theater or
Multichannel Audio System the Right and Left Front
Channels from an Audio/Video Processor or Surround
Decoder can Passthru from the assigned MA9000
Input, into the MA9000 Power Amplifier Circurity.
The Passthru Audio Signal is also available for a
separate external Power Amplifier(s) via the number
1 Preamplifier Output Jacks. The Setup Mode allows
selection of the specified MA9000 Input to be used
for the Right and Left Front Channels. In the example
below, the Right and Left Front Channels from the
Audio/Video Processsor will be connected to the UN-
BALANCED 6 INPUT Jacks on the MA9000. Refer
to page 9 for additional connection information.
Note: The Phono and Digital Inputs are not assignable as a Passthru Input.
1. Press and hold in the INPUT Control to enter the SETUP MODE. Refer to figure 2 on page 17.
2. Rotate the INPUT Control until SETUP: Passth- ru, Off appears on the Information Display.
Refer to figure 37.
3. Rotate the VOLUME (ADJUST) Control to select SETUP: Passthru, UNBAL 6 Input. Refer to
figure 38.
4. Exit the SETUP Mode by several presses of the INPUT Control. The USB Automute Feature helps to ensure noise free
playback of streaming music via the MA8900 USB In-
put, as the Digital Audio Signal format changes (PCM,
DSD, etc.). On occasion due to the way a Digtal Audio
Music Recording was made, it may become desirable
to switch Off the USB Automute Feature. To switch
Off Automute, perform the following steps:
1. Press and hold in the INPUT Control to enter the SETUP MODE. Refer to figure 2 on page 17.
2. Rotate the INPUT Control until SETUP: USB Automute, ON appears on the Information Dis-
play. Refer to figure 39A.
3. Rotate the VOLUME (ADJUST) Control to select SETUP: USB Automute, OFF Input. Refer to
figure 39B.
4. Exit the SETUP Mode by several presses of the INPUT Control.
