McIntosh MX150 7.1 A/V Surround Sound Processor

For sale is this very nice MX150 which has been fully upgraded to the MX151 via
firmware and features the 3DHDMI upgrade. 

This unit was tested for functionality by Pyramid Audio in
Austin, Tx and came away with no issues.

It comes with the power cord and a proper McIntosh Labs Inc. packing box. (The box is labeled for an MX122). I’m also
including a brand new Harmony 650 replacement remote that features a color screen.

It does not have the original manual nor does it have the RoomPerfect
microphone, stand or cable. But you can easily get a replacement microphone for
about $50 to $100 dollars online and be able to use the outstanding Room Correction
function of the MX150, one of the best selling features of this particular
unit, all at a fraction of the original price. Here is an example mic that you can use:

For the just the sound processing, home theater sound and room
correction features, this is a great way to get a complete McIntosh preamp and get into the McIntosh game. If
you want the very latest in video processing, it’s better to just have a dedicated
HDMI switcher that feeds into your TV anyway. McIntosh is all about the music
(and sound).

The glass is perfect, no chips, bubbles or anything wrong. 

At the top of the front there
are two spots that had a scratch on the metal and there was some ink applied to hide it. You can’t even really tell unless you are really looking for it and you are at the
right angle of light, not a big deal at all.

The VFD display which, when turned on at
first, seems a bit dim. After warming up it gets better and seems fine. But
there are still some little areas, depending on the text, that seem slightly
dimmer than neighboring text, (even after warming up.) I have included a picture to better show this. It’s strange because
usually the VFD displays are known for their longevity and robustness. I was
quoted about $500 to have it replaced but it’s not bad enough in my opinion to
justify the expense. You can see in the pictures it seems fine but the photos do
make it seem brighter than it is in reality. Still, you can see how it’s not
that bad.


The vast array of digital and analog inputs can be custom labeled for
simplified system operation and matched in volume level for a smooth transition
between sources.

Features built-in Dolby® TrueHD and DTS-HD Master Audio™ decoding for
the latest Blu-ray disc™ soundtracks. Two channel stereo source materials may
be played back in stereo or processed up to 7.1 multi-channel using Dolby Pro
Logic® IIx or DTS Neo:6 decoding

Built-in Dual Zone feature allows operation of two audio / video zones
to play different media simultaneously in separate rooms with independent
program selection and control.

Assignable balanced input and outputs, analog phono section, bass and
treble tone controls, and full RoomPerfect room correction all enhance the two
channel audio
experience of the MX150.

Two special features with this are the McIntosh built-in RoomPerfect (aka MEN 220) that
you get with the purchase of the MX150. The RoomPerfect feature allow rapid and
accurate measurement of the user’s room acoustics which allow RoomPerfect to seamlessly
integrate the speakers for maximum music and movie sound quality.

The second is that the MX150 supports a complete web-based configuration
and control via an internal web application. Connect an Ethernet cable to the
MX150 and the processor automatically configured itself onto your home network.
Opened a browser, connect to the IP address of the MX150, and there is an application
for configuring the MX150. (refer to manual for full set up instructions). This one has had its IP address set to:

(Note: One of the MX150 Zone A Video OUTPUTS must be connected to the
video input of a Monitor/TV for viewing the On Screen Menus.)
