Two-Way Bookshelf Speaker
Integrated Audio System: The MXA70 Integrated Audio System features a
compact, yet fully functional 50 watt stereo amplifier and a pair of specially
designed two-way speakers that deliver a high level of performance. The system's
analog & digital inputs
provide flexibility to connect a variety of your music sources.
Classic McIntosh Design: The integrated amplifier is housed in a
beautiful polished stainless steel chassis that not only compliments the classic
glass front-panel, knobs, brushed aluminum end caps and gloss black speakers,
but also blends nicely with almost any room decor. Stereo Amplifier w/ ThermalTrak:
The McIntosh MXA70's
integrated amplifier will deliver 50 watts per channel with less than 0.005%
distortion at 8Ω from 20Hz
to 20,000Hz. The integrated amplifier uses ThermalTrak output transistors for
lower distortion and cool operation.
Specially Designed Power Supply: The large power transformer, multiple large filter capacitors and regulated
power supply ensure stable noise free operation.
Electronic Input Switching w/ Naming: The integrated amplifier uses Logic Circuits controlling Electromagnetic Switches on all inputs and operating functions for reliable, noiseless, distortion free switching.
The default Input Names can be changed to match the name of the component
connected to it or any other custom name desired (up to 8 characters).
Balanced & Unbalanced Analog Inputs: The McIntosh MXA70 Integrated
Audio System is equipped with one balanced stereo XLR input and one unbalanced
stereo RCA inputs. Balanced connections
guard against induced noise and allow long cable runs without compromising sound
Digital Audio Inputs: The McIntosh MXA70 system offers one optical
(toslink) digital input, one coaxial (RCA) digital input, and one AES/EBU (XLR)
digital input. The digital inputs will decode 2ch stereo PCM music files at up
to 24-bit/192kHz for high resolution audio playback.
Asynchronous USB-B Input: The McIntosh MXA70 features a
asynchronous USB-B input for playing back music files from your computer.
Asynchronous technology allows the digital clock inside the MXA70's DAC to
control the flow of data coming from your computer. This method of communication
leads to less jitter (timing errors) for the MXA70 to deal with which results in
clearer more defined sound. The MXA70 can decode and play back high res 2ch
stereo PCM audio signal up to 32-bit/192kHz from your Windows PC or Mac
computer. Your Windows PC or Mac computer must meet the following system
- Windows 7 (SP1), Windows 8, Windows 8.1, Windows 10; a Windows PC will
require the installation of McIntosh's USB Audio Window Driver (available on
the McIntosh website)
- Mac OS X 10.6.8 or later; a Mac computer does not require the
installation of an additional USB audio driver
Binding-Post Speaker Terminals: McIntosh Patented
gold-plated, binding-post speaker terminals deliver high current output to the
included pair of bookshelf loudspeakers. These binding post terminals will
accept large diameter wire (up to 10AWG), banana plugs (single only), and spade
Preamp Output: The McIntosh MXA70 is fitted with a stereo
RCA preamp output to send an unaltered audio signal to another amplifier, or to
add a powered subwoofer to your system.
Headphone Amp: For those times when you want to enjoy your music even more intimately, the
MXA70 includes a dedicated headphone amplifier that takes advantage of unique
McIntosh technologies to yield the best possible personal listening experience.
On the front-panel of the MXA70 is a 1/4" headphone jack. The
automatically switched off when headphones are connected.
- Autoformer Technology: The integrated headphone amplifier employs a new adaptation of McIntosh Autoformer
technology to produce three headphone impedance ranges (8-40Ω
/ 40-150Ω / 150-600Ω) so every headphone will
receive the optimal McIntosh sound.
- Headphone Crossfeed Director (HXD): The headphone amp also features
McIntosh's new Headphone Crossfeed Director (HXD) to allow high quality
recordings to image like conventional speakers in your headphones.
Audio Settings: The MXA70 Integrated Audio System offers a variety of
audio adjustments to tailor the sound to your application & preference.
- Bass Boost: The intensity
of the low frequencies in the music can be increased by using the Bass Boost
function. The Bass Boost can be adjusted from 0dB to +12.5dB in 2.5dB
- Balance Left/Right: You are also able to balance the
output level of the integrated amp's left & right output channels.
- Stereo/Mono Mode: By default the Stereo mode is active
for all input sources. However, any input source may be assigned to Mono
mode. Mono mode combines the Left and Right channel input signals for
- Source Level: Each audio source input can be matched in
level, preventing abrupt changes in volume levels.
Front-Panel & Remote Control: Front-panel controls
includes an Standby/On button, a Input Selector knob, and a Volume knob. The
included IR remote offer full wireless operation over the MXA70 system.
Front-Panel OLED & Illuminated Meters: The integrated amp's
front-panel OLED display indicates source selection, volume levels, trim
settings, and setup functions. The illuminated power output meters on the MXA70
are peak responding, and indicate the output of the integrated amplifier. Power Control:
The MXA70 has the ability to automatically
switch power on or off to and from source components via the Power Control
In/Out connections (3.5mm).
Protection Circuitry: The patented McIntosh Power Guard
circuit prevents amplifier clipping and protects your valuable loudspeakers &
headphones. Sentry Monitor protects the power output circuitry and headphones in
the event of an impedance mismatch. Built-in Thermal Protection Circuits guard
against overheating. Direct Current Detection and Protection is provided for
both headphones and loudspeakers.
Mounting Options: The
integrated amplifier is designed to be placed upright on a table or shelf,
standing on its feet. Allow at least 12"
above the top and 0.625"
below the bottom of the
Amplifier, so that airflow is not
obstructed. Allow 19" of depth
for airflow and cable
Dimensions: The MXA70's integrated amplifier measures 11.5" (w) x
5.5625" (h) x 14.625" (d), and weighs 26 lbs.
Two-Way Bookshelf Speaker
Two-Way Speaker Design: The MXA70 Integrated Audio System
includes a pair of two-way bookshelf loudspeakers rated at 8Ω
that can handle 50 watts of continuous power. Each bookshelf speaker
features one 0.75" titanium tweeter and one 4" woofer with a 2,000Hz crossover.
- 0.75" Tweeter: The 0.75" titanium dome tweeter reproduces high
frequencies up to 45,000Hz. The tweeter's voice coil is magnetic-fluid
cooled for less thermal compression.
- 4" Woofer: The 4" cone woofer reproduces low frequencies down to
60Hz. The woofer has very large magnetic flux stabilizing elements that help
it deliver lower bass notes with less distortion.
Bass Reflex Enclosure: The two-way bookshelf loudspeakers
utilize a bass reflex cabinet with rear firing port for greater efficiency and
bigger, deeper bass response. The speaker cabinets are made of durable cast
aluminum and finished with high gloss black finish. Each speaker cabinet
includes a removable black knit cloth grille. The speaker cabinets can be angled
upward for greater sound dispersion.
Gold-Plated, Binding-Post Terminals: Each bookshelf
loudspeaker features McIntosh Patented gold-plated, binding-post terminals to
receive high current power & audio signal from the MXA70's integrated amplifier.
These binding post terminals will accept large diameter wire (up to 10AWG),
banana plugs (single only), and spade lugs.
Mounting Options: These bookshelf speaker can be simply placed on a
stand, shelf, desk, or tabletop. There are no wall-mount options.
Dimensions: Each two-way bookshelf loudspeaker measures 5" (w) x
10.875" (h) x 10.75" (d), and weighs 25 lbs..
