MA6500
Integrated
Amplifier

“all the premium features

you dream of in a

convenient

integrated amp”

Introduce yourself to McIntosh quality with the MA6500
Integrated Amplifier.

Hardly a “slimmed down” model, the MA6500 incorporates premium
McIntosh technologies, including Power Assurance and Silent
Electromagnetic Switching, as well as several features that will assist
you as you integrate and expand your McIntosh system.

At the Heart of the MA6500’s Power Assurance System is Power Guard
clipping protection, input volume reduction that acts literally at the speed
of light to keep distortion below 2% and deliver clipping-free output.
Sentry Monitor current protection, Thermal Cutout, Turn-On Delay and
Soft start inrush protection join Power Assurance to protect and prolong
the life of your equipment.

Silent electromagnetic switching gives the MA6500 distortion-free switch­ing. A glass tube containing oxygen-free gas and two signal leads sits in
a copper coil and shock absorbent plastic, awaiting DC voltage to create
a magnetic field that delivers the input signal and completes the circuit.

EXCLUSIVE MCINTOSH POWER

ASSURANCE SYSTEM

A collection of technologies that

enhance performance and

reliability and protect the amp and

the loudspeakers.

Power Guard clipping protection.

A waveform comparison circuit

continuously monitors both input

and output signals and dynamically

adjusts the input level to insure

maximum output power while

preventing harsh sounding

clipping distortion.

Sentry Monitor current protection

continually senses the voltage and

current of the output stage and

confines it to a safe limit, without

limiting power output.

Thermal cutouts protect your amp

from overheating if cooling air is

blocked and transistors

become too hot.

DC failure protection guards

speakers against output

circuit failure.

Turn-on delay slows operation for

about two seconds after turn-on in

order to avoid any pops or

thumps generated as other

equipment turns on.

Soft Start inrush protection

eliminates component stress

during turn-on. Thermistors in the

power transformer act as a

cushion against inrush current.

Soft Start is one of many details
that contribute to the remarkable
longevity of McIntosh equipment.
