I had the same problem with my mt. You pretty much have to attenuate the sbd signal for the mt, to answer your question.
The answer for me was the shure attenuators. I don't take sbd patches anymore and only used them twice. They were pretty pricey, if you are interested I will make you a sweet deal on them.
pm me if you are interested in the shure attenuators. Bassically buy one and get the other free kind of deal. Mint condition, used twice.
Peace,
Tom
