Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

While the video section of this unit is outdated, the audio section is still relevant and makes for a great full function audio processor. Especially if you like to use your system for music as well as video.

This MX135 is in great working condition and has been fully tested. The audio quality is very good, and the controls are responsive and fully operational throughout.

Cosmetically it's close to perfect. The glass is mint with all lettering intact. The knobs are all clean and scratch free.

The MX135 also utilizes fiber optic distributed lighting for the faceplate, so no need to mess around replacing bulbs in the future.

Your purchase also includes a remote control and a power cord. We have an official McIntosh Shipping carton on order. 

*The factory optional AM/FM Module is NOT included/installed.

McIntosh Performance Features Include:
• Balanced Inputs and Outputs
Two pairs of Balanced high level Inputs and an eight chan- nel Balanced Output are provided.

• Pure Stereo Outputs
When Stereo Operation is selected for an analog source,
pure, unprocessed stereo signals appear at the left and right front outputs.

• External Eight Channel Input
An external eight channel signal processor can be con-
nected to these inputs as well as a DVD-Audio Player or Super Audio Disc Player with a built-in processor.

SkyFi Setup Notes:
• This MX135 was reset to factory default settings.
• Balanced inputs 1 and 2 are assigned to CD1 and CD2 respectively.

The SkyFi Testing Process for Preamplifiers/Processors:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale signs of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline.

At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching.

Final testing involves putting actual music through the preamplifier. We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage KEF speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
