Mx135 subwoofer not working???

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.

Still having no luck. But have noticed that sub out does work for 10-15 minutes, the gradually fades to no output. Again, this is only in pure mode. I have ruled out the subwoofer itself. Sub out works great in any DSP mode, just not analog stereo. Perhaps it is a heat or capacitance problem?

That's a bummer Tom. It sounds like you might need to enlist the help of a service tech for this fix. Audio Classics in Vestal, NY could help you out. Give Ryan a call. These guys are extremely knowledgable and do great work. Best of luck!
