The Pro Sub Isolator

MSB is thrilled to finally provide an elite solution for the modern powered subwoofer - The Pro Sub Isolator. Typically, parasitic powered sub amplifiers degrade the delicate signal quality from the DAC or preamp by back feeding noise onto the signal lines. That additional low-level noise gets magnified by the main power amplifiers and adds a significant drop in performance to the system. The genius of the Pro Sub Isolator is to tap into the signal at the speaker level where its influence is negligible. Once the delicate preamp signal has been put through power amplifiers, it becomes rugged enough to ignore feedback generated by the lower-class amplification of the powered subwoofers. The new design works by lowering the already amplified signal down to the appropriate level using an audiophile grade transformer to isolate the incoming signal. The Pro Sub Isolator offers a refined solution with improved clarity and dynamics for those pushing their listening experience to a whole new dimension.

Flexible Configurations

The Pro Sub Isolator input features a set of speaker binding posts which can be connected via banana plugs or spades directly to your speaker or power amplifier output. We recommend using the alternate style connectors of your current system. Please do not stack spade connections under a single binding post. The Pro Sub Isolator uses very little power from the speaker level signal, so light cabling can be used in lieu of high power speaker interconnects. Audiophile cables are often bulky, so we designed the input lugs to feature indexable rotations to adjust the angle at which the spades can attach to the unit. Please reach out to your local tech or to MSB directly to have yours configured.
