Now you can take advantage of traditional McIntosh
standards of excellence in the MXA80 Integrated
Audio System. The Power Amplifier section of the
MXA80 will drive Headphones or Loudspeakers to a
high level of performance.
The flexible Preamplifier section provides con-
nections for various input sources, including Digital
sources and music streaming from the Internet via an
USB Computer connection.
The MXA80 reproduction is sonically transparent
and absolutely accurate. The McIntosh Sound is “The
Sound of the Music Itself.”
Introduction
Performance Features
• Power Output
The McIntosh MXA80 is designed for connection of a
single 8 ohm Loudspeaker per channel and will deliv-
er 50 watts per channel with less than 0.005% distor-
tion. The Power Amplifier uses ThermalTrak
1
Output
Transistors for lower distortion and cool operation.
• Autoformer Designed for Headphones
The MXA80 Amplifier uses a specially designed Au-
toformer for Headphones. There are three selectable
impedances ranges, allowing connection of Head-
phones from 8 ohms thru 600 ohms.
• HXD
®
for Headphones
The MXA80 Headphone Crossfeed Director Circuitry
(HXD
® )
improves the sound localization for Head-
phone Listening. HXD
®
restores the directionality
component of the spatial sound stage normally heard
with Loudspeaker listening.
• Automatic Output Switching
The MXA80 has a Front Panel one-quarter inch Head-

phone Jack for private listening. Loudspeaker Listen-
ing is automatically switched Off when Headphones
are connected.
• Superior Protection
McIntosh Sentry Monitor Protection Circuits ensure a
long and trouble free operating life. It also protects the
Headphones in the event of an impedance mismatch.
Thermal Protection guards against overheating and
Direct Current Detection Protects both Headphones
and Loudspeakers.
• Electronic Switching for Analog Inputs
The Preamplifier uses Logic Circuits controlling Elec-
tromagnetic Switches for reliable, noiseless, distortion
free switching.
There is a Balanced and Unbalnced
Input for connection of source components.
• Digital Audio Inputs
The MHA150 has four Digital Audio Inputs to decode
PCM Signals. When the Coaxial, Optical and MCT
Inputs receive a PCM Signal, the MHA150 upsamples
the Digital Signal to 192kHz with 24Bit resolution
before the Digital to Analog process begins. The
Digital MCT Input Circuitry directly decodes SACD/
CD signals from an external Transport component.
The USB Input for streaming audio, processes Digital
Signals up to 384kHz with 32Bit resolution, decodes
up to DSD256 Digital Signals and DXD 24Bit with a
sampling rate up to 384kHz.
• Multifunction OLED Display
The Front Panel Display indicates source selection,
volume levels, trim settings and setup functions.
• Illuminated Meters
The Illuminated Power Output Meters on the MXA80
are peak responding, and indicate the output of the
amplifier.
• Power Control and Remote Control
The Power Control Output connection provides conve-
nient Turn-On/Off of McIntosh Source Components.
• Special Power Supply
The large Power Transformer, multiple large filter
capacitors and regulated Power Supply ensure stable
noise free operation even though the power line varies.
• McIntosh Custom Binding Posts
McIntosh Patented gold plated output terminals deliver
high current output. They accept large diameter wire
and spade lugs.
• Glass Front Panel and Super Mirror Chassis
The even Illumination of the Front Panel is accom-
plished by the combination of custom designed Fiber
Optic Light Diffusers and extra long life Light Emit-
Z *[\Z% ] ^-
ror Finish Chassis ensures the pristine beauty of the
MXA80 will be retained for many years.
• High Excursion Woofer and Dome Tweeter
The 4” Woofer/Midrange delivers lower bass notes
with less distortion. The three-quarter inch titanium
tweeter reproduces frequencies up to 45,000Hz.
• Cast Aluminum Loudspeaker Enclosure
The durable cast aluminum enclosure is finished in a
high gloss, piano black. All of the components making
up the Loudspeaker were designed to achieve correct
time arrival in the reproduced musical sound (also
