Our take on the McIntosh MXA70

McIntosh is legendary for their high-end separates (preamps and power amps). But they also understand the convenience offered by a compact stereo system. The MXA70 packs superb McIntosh performance into a design that's meant for tight spaces. Whether you're using it in your living room or bedroom, this setup will deliver plenty of rich, warm sound. All that's missing are your source components — and there are enough inputs to handle a wide range of them.

All-in-one McIntosh system

McIntosh is legendary for their high-end separates (preamps and power amps). But they also understand the convenience offered by a compact stereo system. The MXA70 packs superb McIntosh performance into a design that's meant for tight spaces. Whether you're using it in your living room or bedroom, this setup will deliver plenty of rich, warm sound. All that's missing are your source components — and there are enough inputs to handle a wide range of them.

High-res audio

Versatile, high-performance amp

The heart of the MXA70 is the stereo integrated amp. It's pure McIntosh, with a beautiful glass front panel, illuminated output meters, and a rock-solid aluminum chassis. The back panel offers digital and analog inputs, including balanced XLR, optical and coaxial digital, and even a USB input. That means you can connect everything from disc players, turntables, a computer, and more. The power amp section offers plenty of clean power to drive the included speakers. The five-step bass boost helps you dial in your custom tone. Want more bass? There are preamp outputs so you can add a powered subwoofer of your choice.

They know speakers, too

If you don't think of McIntosh as a leader in speakers...well, you really should. They have a rich history of making loudspeakers that earn accolades from lots of reviewers. The compact two-way speakers included with the MXA70 are an excellent introduction. Their high-excursion 4" woofers produce accurate, low-distortion midrange and bass. The 3/4" titanium dome tweeters offer extended frequency response for highs that shimmer with detail. They also offer a unique built-in stand that allows them to rest flat or be angled up, making it easier to get optimum sound no matter where you place them.

Get the most from your headphones

Want your own private listening session? Break out your best headphones and plug them into the front-panel 1/4" jack. The MXA70's built-in headphone amp will bring out the best in them — even demanding headphones that require a lot of power. An impedance switch lets you match the power output to your 'phones, ensuring that this amp delivers outstanding sound with just about any pair you use. Plus, McIntosh's Headphone Crossfeed Director restores directionality to the soundstage, so listening through your headphones more closely resembles the spaciousness offered by speakers.

A world-famous audio heritage, made in America

Since its founding in 1949, McIntosh has defined the meaning of high-quality sound reproduction, while setting industry standards for superior performance and reliability. The company is based in Binghamton, New York, where its high-end components and speakers are still individually handcrafted by a team of skilled experts. This uncompromising dedication to quality has made McIntosh one of the most recognized and respected audio manufacturers in the world.

Add wireless music to the mix

If you want to add wireless tunes from your smartphone or online services like Spotify® to the MXA70, get the McIntosh MB50 streaming audio player. It's a simple way to add tons more music to your system, and control it wirelessly using your smartphone or tablet.

    Integrated Amplifier
    Two-Way Bookshelf Speaker

    Integrated Amplifier

    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 quality.

    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 requirements -

    • 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 lugs.

    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 connected loudspeakers 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 increments.
    • 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 Monophonic Sound.
    • 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 connections.

    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.
