Thumbs up Consider the source

It is the most complicated piece of gear you will ever encounter and has to be set up exactly per the manual or you will have a continuous series of head-scratching issues.

Most of the gear I have I can just kind of wing it for setup. Not the MX 151.

The manual describes a series of steps you must take, in exact order, to properly setup your MX 151.

You will need to connect a TV to the HDMI output to see all the menus. You cannot easily set the unit using the front panel displays and remote.

The setup instructions begin on page 17 with how to enter the installer setup menu and continue on page 22 with detailed setup instructions.

The procedure for re-setting to factory defaults is on page 45.

Once you have reset your unit to factory defaults you MUST follow the manual setup directions, in order. Do not skip any steps.

Good luck!
Although it required a lot of moving gear back and forth between our stereo listening area and the room we presently watch TV in [read: they are separate rooms], I managed to get some kind of joy with this issue.

Although I did reset the Mac MX151 to its factory defaults -- as per Pg 45 of the MX151 Owner's Manual -- I still couldn't say whether or not going through its internal step menus (several times), via an HDMI connection to our TV, did any good. To the contrary, I believe that hooking up our source, the Oppo 105D, to the TV (also via HDMI) made all the difference.

We don't own one, but I managed to find the User Manual for the Oppo 105D on the Oppo website. If you study pages 69-70 of said manual, you will come across a major heading called Audio Processing Setup. Under this heading are the subsections "Speaker Configuration" and "Down Mix Mode," which, once configured properly, will have an effect on the source's surround output(s).

The music we're presently experimenting with was mixed for quad listening, so certain considerations have to be made. Nevertheless, I set the Oppo 105D up for 5.1 channels and went through adjusting each speaker -- Left Front, Right Front, Left Surround & Right Surround -- separately to "bring them out" for a quad listening session. Once I moved the 105D back to our music listening area, I finally managed to get some life out of our MC300, which we're presently using to power our B&W N805 surround speakers...and, once that was accomplished, the quad mix I've been dying to hear sounded very sweet indeed.

I plan on hooking the Oppo 105D back up to our TV to do some fine tweaking to each speaker in the setup, but the important thing right now is that, by considering the source (the 105D), we managed to realize some surround sound.
