McIntosh MA7000 - LITERATURE User Manual

MA7000
integrated amplifier
l e g e n d a r y
Designed to deliver a continuous 250 watts per channel, the MA7000 Integrated Amplifier
is the most powerful integrated amplifier McIntosh has ever offered. The MA7000 leads
an already impressive array of McIntosh integrated amplifiers delivering uncompromised
performance in a convenient, single-box solution.
The MA7000 employs the famous McIntosh Autoformer. Designed and manufactured
exclusively by McIntosh, the Autoformer helps the MA7000 deliver optimum performance
with any loudspeaker. Whether your speakers are 2, 4, or 8 Ohms the McIntosh Autoformer
ensures that you will always get all of the power that you have paid for.
The MA7000 is the beneficiary of many technologies used in McIntosh separate
components yielding uncompromised performance from a single chassis. A McIntosh
designed 5-band equalizer guarantees the range of adjustment necessary to extract the
maximum sound quality from a wide variety of audio sources and software, while the
Fiber-Optic Illuminated Glass Front Panel insures that the appearance of the MA7000
will remain like new for many decades.
