The MA9000 Integrated Amplifier can help you achieve
audio perfection. Our largest integrated in both size and power, it offers 300
Watts per channel and combines our amplifier and preamplifier expertise into
one comprehensive unit.
There are enough inputs and outputs on the
MA9000 to last a lifetime. The 10 analog connections are comprised of 2
balanced and 6 unbalanced inputs plus 1 Moving Coil and 1 Moving Magnet
for turntable connectivity.
Both phono inputs feature adjustable loading for fine tuning of vinyl playback.
All unbalanced analog connectors are made from premium gold-plated solid brass
for superior signal handling and grounding. On the digital side, 2 coax, 2
optical, 1 USB and 1 MCT input (for use with our MCT450 SACD/CD Transport)
are all housed in our new DA1 Digital Audio Module; the DA1 can be easily
replaced by future modules to keep your MA9000 up to date as new digital audio
formats and technologies are developed. The DA1 utilizes a powerful 8-channel,
32-bit Digital-to-Analog Converter (DAC) used in Quad Balanced mode. The coax
and optical inputs will decode music up to 24-bit/192kHz for high resolution
audio playback; the USB input accepts even higher PCM signals up to
32-bit/384kHz and supports up to DSD256 and DXD 384kHz. All inputs can be given
custom names for user-friendly system control and configuration. All inputs
also function independently of each other and each is always available for use
regardless of how your sources are connected.
The MA9000 features our new McIntosh
Monogrammed Heatsinks™ that are made from high quality materials with excellent
thermal conductivity properties. They are so efficient at dissipating heat that
they warrant bearing the McIntosh “Mc” logo. They also have a higher quality
finish thanks to a new manufacturing process. They are connected to advanced
high current output transistors that eliminate thermal equilibrium lag time (or
warm-up time), meaning the first note played will sound just as good as those
played later in your listening session.
New, more powerful control microprocessors
have been used in the MA9000 to improve overall system operation. Some of the
latest audio-grade circuit components have also been utilized to allow the
MA9000 to deliver the best sound possible. At 300 Watts per channel, the MA9000
has enough power to properly drive virtually all loudspeakers – and our
renowned McIntosh Autoformer guarantees your speakers will always receive that
full 300 Watts regardless if they have 2, 4 or 8 Ohm impedance. Other McIntosh
features included in the MA9000 are:
·
Power Guard® that monitors
and adjusts the sound wave at the speed of light to prevent harsh sounding
distortion and clipping that could damage your speakers
·
Sentry Monitor™ is our fuse-less short-circuit protection circuit that
disengages the output stage before current exceeds safe operating levels and
then resets automatically when operating conditions return to normal
·
Home Theater PassThru that allows for seamless integration into a home theater system
·
High Drive headphone amplifier with Headphone Crossfeed Director (HXD®) which can bring an
added dimension to headphone listening
·
A discrete, eight-band tone control that allows for advanced manual analog
adjustment of your favorite recordings
·
Power Control to send power on/off signals to connected McIntosh components
for easy system power up and shutdown
·
Our patented Solid Cinch™ speaker binding posts that easily but securely
attach the speaker cables to prevent them from coming loose and possibly
causing a short; the binding posts are also gold-plated to prevent corrosion
and ensure a quality signal is sent over your speaker cables to your speakers
The entire unit is wrapped in the classic
McIntosh aesthetic with blue watt meters, a black glass front panel, control
knobs, illuminated logo, aluminum end caps with built-in handles and a
beautiful polished stainless steel chassis. Contact your local dealer to learn more.
