What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

McIntosh MA 9000


The MA9000 Integrated Amplifier can help you achieve audio perfection. Offering 300 Watts per channel, it is ur largest integrated.
Features our new McIntosh Monogrammed Heatsinks™ that are so efficient at dissipating heat that they warrant bearing the McIntosh “Mc” logo.
All digital inputs are housed in our new DA1 Digital Audio Module which can be easily replaced by future modules to keep your MA9000 up to date as new digital audio formats and technologies are developed.
Supports high resolution digital music up to DSD256 and DXD 384kHz via a Quad Balanced 8-channel, 32-bit/192kHz DAC.
All unbalanced analog connectors are made from premium gold-plated solid brass for superior signal handling and grounding.
The MA9000 is full of McIntosh technological staples including Autoformers, Power Guard®, Sentry Monitor™, Home Theater PassThru, High Drive headphone amplifier with Headphone Crossfeed Director (HXD®),
Power Control and Solid Cinch™ speaker binding posts.


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.
