Introduction
Now you can take advantage of traditional McIntosh standards 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 transparent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”

• 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 output 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.

How to Connect Loudspeakers
Caution: The supplied AC Power Cord should not be
connected to the Rear Panel of the MA6300
Amplifier until after the Loudspeaker Connections have been made. Failure to observe this
could result in Electric Shock. For additional
instruction on making Loudspeaker Connections contact your McIntosh Dealer or McIntosh Technical Support.
When connecting Loudspeakers to the MA6300 it is very
important to use cables of adequate size, so there is little to
no power loss in the cables. The size is specified in Gauge
Numbers or AWG (American Wire Gauge). The smaller
the Gauge number, the larger the wire size:
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 14 Gauge.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 12 Gauge.
1. Prepare the Loudspeaker Hookup Cables that attach to
the Amplifier by choosing one of the methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures 1, 2 & 3. If the cable is
stranded,
carefully
twist the
strands
together as
Figure 2
Figure 3
Figure 1
tightly as
possible.
Note: If desired, the twisted ends can be tinned with
solder to keep the strands together, or attach
spade lug and/or banana connector.
Spade lug or prepared wire connection:
Insert the spade lug connector or prepared section
of the cable end into the terminal side access hole,
and tighten the terminal cap until the cable is firmly
clamped into the terminal so the wires cannot slip
out. Refer to figures 4, 5 & 6.
10
Banana plug connection:
Insert the banana plug into the hole at the top of the
terminal. Refer to figure 7.
Note: Banana Plugs are for
use in the United States
and Canada only.
2. Connect the loudspeaker hookup
cables to the output terminals
that match the impedance of your
loudspeakers, being careful to
observe the correct polarities.
3. Connect the MA6300 Power Cord to a live AC outlet.

How to Connect an External Power Amplifier
How to Connect an external Power Amplifier
The MA6300 has the ability to be connected to an external Preamplifier and/or Power Amplifier. In the example
below, the MA6300 is connected to an external McIntosh
Power Amplifier and to a McIntosh Loudspeaker with
Bi-amplifer connections. The MA6300 Power Amplifier
drives the Midrange/High Frequency Section and the external Power Amplifier drives the Low Frequency Section
of the Loudspeaker.
1. Remove the McIntosh Jumpers connected between the
MAIN OUT and POWER AMP IN Jacks. Retain them
for future use.
2. Connect a pair of “Y” jumper adapters between the
MAIN OUT and POWER AMP IN Jacks.

Packing Instructions
Packing Instructions
In the event it is necessary to repack the equipment for
shipment, the equipment must be packed exactly as shown
below. It is very important that the four plastic feet are attached to the bottom of the equipment. This will ensure the
proper equipment location on the bottom pad. Failure to do
this will result in shipping damage.
Use the original shipping carton and interior parts only
if they are all in good serviceable condition. If a shipping
carton or any of the interior part(s) are needed, please
call or write Customer Service Department of McIntosh
