Sign in to disble this ad
Folks, I recently exchaged a new RH450 (didn't quite do it for me) for an MB500 that is the BOMB! The only wrinkle is that I have one Speakon cable and was trying to attach a second cab using the 1/4" connector in the dual purpose Speakon connectors in the rear of the unit and the 1/4" would go in only half way (and was EXTREMELY tight) and would not seat no matter how had we tried to push it in. Has anyone else experienced this?
I'm assuming I'll need to exchange it or buy another Speakon.
Bob G. are you out there?
Thank you!
Earl

Interesting, looks like speakon's are the way to go. It's no big deal but makes a guy wonder if it's a typo in the manual or a manufacturing error??

I wonder if the combo jacks were on the old MB2 and just didn't make it to the newer version (or they had a crapload of the older non-combo speakons and decided to get rid of 'em!)
Bad form, GK, bad form!

Anywho....I love my MB500! Totally rocks my socks.

There is a lot of very transparent lows on that amp and I have had to re-glue several of my old cabs and tweak back the bass knob. |

|  | Registered User | | | | FWIW, I had a MB500, ordered new 2 months ago. I ending up returning it. But, included in the paperwork, there was an additional page that stated that the speakon was no longer a combo connector. The manual stated otherwise. But there was an amendment to the owners manual.  |
