Mx135 subwoofer not working???

I owned an MX135 but it's been a few years, so forgive my "guess
from faded memory". But I seem to recall that you must set the cross
over in the 2 channel settings menu, but I really seem to recall that the
"pure" excludes the subwoofer. Also if you haven't experienced
this, I definitely do remember having to do a capacitance reset, by
unplugging the unit and press every switch and turn the knobs while it is
unplugged. That allows the processors to return to their default settings,
and sometimes that helps get a setting change to be accepted.
Good luck, but look at your manual, I really do think that the subwoofer is
not used in pure mode. But could be wrong, dang that could hurt! :)

If the mx-135 is designed similarly to my mx-120, then Pure Stereo mode should output a sub signal, and 2-channel mode, no sub signal. Did you try doing a hard reset?

Dtomasol-

if you want the best sub in the market, sell your current sub and buy a REL. These are the most musical sub out there.
Everything else is a waste of money. Keep me posted & Happy Listening!

I'm convinced Jafant is an auto spambot that searches for the word subwoofer, and adds irrelevant non sequiturs to REL products.

Be sure to keep it posted.
