I saw this quote on "Ted's Tip For Today" on Weber's web site. I didn't realize that was the case. That could be useful for some people who are trying to match odd impedances, want to mix different cabs, etc. With all Weber attenuators, once you have selected the proper impedance to match the output impedance of the amp, the actual speaker impedance isn't critical. That's because the actual load to the attenuator becomes the speaker impedance plus the output section of the attenuator, while the amp continues to see the correct nominal impedance from the input section of the attenuator. That's why, on the MASS, we provide two speaker output jacks. Feel free to experiment with different impedance speakers, cabinets, etc.

Cool info - thanks! I previously posted asking whether there was a way to run my 8 ohm Z-Best and my 4 ohm Rivera 212 together at once with my 6545. I think the general consensus on that thread was that I had a mismatched impedence problem. Looks like the MASS could be one solution.
Cheers, Blair

I wonder if in bypass or no attenuation it's the same deal.

I just asked Ted about that. The attenuator MUST be engaged to do this. So, you can turn the attenuator all the way up, but there is still some attenuation (about 3db, if I remember correctly).
