XLR Connectors
Below is the Pin configuration for the XLR Balanced
Input Connectors on the MA6300. Refer to the dia-
gram for connection:
PIN 1: Shield/Ground
PIN 2: + Output
PIN 3: - Output
Power Control Connector
The MA6300 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 MA6300.
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 MA6300 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 MA6300 utilizes a phono style Plug-In Jumper to
connect the MAIN OUTPUT (Preamplifier Output)
jack to the POWER AMPlifier INPUT jack for each
channel.
Note: The Jumper Connector is avail-
able from the McIntosh Parts

• Power Output
The MA6300 consists of a 100 watts per channel ste-
reo Power Amplifier and a sophisticated Preamplifier
in one compact unit with less than 0.005% distortion.
• Electronic Input Switching and Balanced Input
Digital Logic integrated circuits drive Electromag-
netic switches on all seven inputs and operating func-
tions for reliable, noiseless, distortion free switching.
The Balanced Input allows the connection of a source
component using long cable lengths, without a loss in
sound quality.
• Power Guard
The patented McIntosh Power Guard circuit prevents
the amplifier from being over driven into clipping
with its harsh distorted sound that can also damage
your valuable loudspeakers.
• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protec-
tion circuits ensure the MA6300 will have a long and
Now you can take advantage of traditional McIn-
tosh standards of excellence in the MA6300 Inte-
grated Amplifier. The Power Amplifier section of
the MA6300, with a power output of 100 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 MA6300 reproduction is sonically trans-
parent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”
trouble free operating life. Built-in thermal protection
circuits guard against overheating.
• Illuminated Power Meters
The Illuminated Power Output Watt Meters on the
MA6300 are peak responding, and indicate the power
output of the amplifier.
• Power Control
The Power Control Output connection provides con-
venient Turn-On/Off of McIntosh Source Components
connected to the MA6300.
• Remote Control
The Remote Control provides control of the MA6300
operating functions and any McIntosh Source Compo-
nents connected to it.
• Special Power Supply
A regulated Power Supply and a special R-Core Power
Transformer, 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 MA6300 will be retained for
many years.
