Shure A15AS XLR attenuators.. anyone tried them?


I'm currently using Rothwell 10db XLR attenuators but need more attenuation before my amplifier. Has anyone tried the Shure A15AS XLR attenuators?

I just bought an NHT PVC Pro passive volume control (at a great close-out price). It sounds fine to me. Attenuator problem solved. Thanks, Bob R.

Anyone has compared the passive NHT PVC Pro to the active SPL Volume 2? Both are XLR devices and operate symmetrical but not fully balanced.
