Now you can take advantage of traditional McIn-
tosh standards of excellence in the MA6600 Inte-
grated Amplifier. The Power Amplifier section of
the MA6600, with a power output of 200 watts per
channel, will drive a pair of quality Loudspeakers to
a high level of performance. The flexible Preamplifier
section provides connections for various input sources
and may also be used to drive an external Power Am-
plifier. The MA6600 reproduction is sonically trans-
parent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”
XLR Connectors
Below is the Pin configuration for the XLR Balanced
Input Connectors on the MA6600. Refer
to the diagram for connection:
PIN 1: Shield/Ground
PIN 2: + Output
PIN 3: - Output
Power Control Connector
The MA6600 Power Control Output Jack sends Power
On/Off Signals when connected
to other McIntosh Components. A
1/8 inch stereo mini phone plug is
used for connection to the Power
Control Output on the MA6600.
Note: The Data and Power Control Connecting Cable is
available from the McIntosh Parts Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo
mini phone plugs on each end.
Data Port Connectors
The MA6600 Data Out Ports send Remote Control
Signals to McIntosh Source Compo-
nents. A 1/8 inch stereo mini phone
plug is used for connection.
McIntosh Plug-In Jumper Connector
The MA6600 utilizes a phono style Plug-In Jumper to
connect the OUTPUT 1 (Preamplifier Output) Jack to
the PWR AMP (Power Amplifier Input)
Jack for each channel.
Note: The Jumper Connector is available
from the McIntosh Parts Department:
McIntosh Jumper Connector Part No. 117-781

• Power Output with Patented Autoformer
The MA6600 consists of a 200 watts per channel ste-
reo Power Amplifier with less than 0.005% distortion.
The McIntosh designed and manufactured Autoformer
allows connection of 2, 4 or 8 ohm Loudspeakers. The
Power Amplifier uses Thermal Trak
1
Output Transis-
tors for lower distortion and cool operation.
• Electronic Switching and Balanced Connections
The Preamplifier uses Logic Circuits controlling
Electromagnetic Switches on all inputs and operat-
ing functions for reliable, noiseless, distortion free
switching.
There is a Balanced Input for connection of
source components.
• Power Guard
The patented McIntosh Power Guard circuit prevents
amplifier clipping and protects your valuable Loud-
speakers.

The type and availability of tuner module(s) for the MA6600
varies from country to country.
• Multifunction Fluorescent Display
The Front Panel Display indicates source selection,
volume levels, tone adjustments, setup functions and
tuner functions when the optional Tuner Module
2
is
installed.
• Illuminated Power Meters
The Illuminated Power Output Watt Meters on the
MA6600 are peak responding, and indicate the power
output of the amplifier.
• Power Control and Remote Control
The Power Control Output connection provides conve-
nient Turn-On/Off of McIntosh Source Components.
The Data Ports together with the supplied Remote
Control provides control of McIntosh Source Compo-
nents connected to the MA6600.
• Special Power Supply
The large Power Transformer, multiple filter capaci-
tors with 100 Jules of Energy Storage and regulated
Power Supply ensures stable noise free operation even
though the power line varies.
• Fiber Optic Solid State Front Panel Illumination
The even Illumination of the Front Panel is accom-
plished by the combination of custom designed Fiber
Optic Light Diffusers and extra long life Light Emit-
ting Diodes (LEDs). The glass Front Panel ensures the
pristine beauty of the MA6600 will be retained for
many years.
