XLR Connectors
Below is the Pin configuration for the XLR Balanced Input
Connectors on the MA6300. Refer to the diagram for con-
nection:
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 con-
nection to the Power Control Output
on the MA6300.
Note: The Data and Power Control Connecting Cable is avail-
able 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 Components. A 1/8
inch stereo mini phone plug is used for
connection.
McIntosh Plug-In Jumper Connector
The MA6300 utilities a phono style Plug-In Jumper to con-
nect the MAIN OUTPUT (Preamplifier
Output) jack to the POWER AMPlifier
INPUT jack for each channel.

• Power Output
The MA6300 consists of a 100 watts per channel stereo
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 Electromagnetic
switches on all seven inputs and operating functions 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 overdriven 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 protection
circuits ensure the MA6300 will have a long and 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 out-
put of the amplifier.
• Power Control
The Power Control Output connection provides convenient
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 Components
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 accomplished
by the combination of custom designed Fiber Optic Light
Diffusers and extra long life Light Emitting Diodes
(LEDs). The glass Front Panel ensures the pristine beauty
of the MA6300 will be retained for many years.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MA6300 Integrated 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
Amplifier. The MA6300 reproduction is sonically trans-
parent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”
