Effective and affordable

This product was a simple solution to a pesky hum issue. Excellent service from Sweetwater as well.

Works as advertised

These did just what I needed them to! We had a buzz in our speaker system and these eliminated it!
by Sweetwater Customer from Knoxville, TN on

Rapco ISOBLOX

Every so often we have had issues with buzzing in our speakers. I never used these before, but after playing a gig where we used our board and the sound company's speaker's we had a buzz. They used something similar to the Rapco ISOBLOX, and it helped. So I purchased a couple of them, Ive only had to use them a few time's but they really work!!! Great investment!

Handy Problem Solver

It does what it's supposed to do: Isolates one ground from another. Audio quality is good. Transformer inside isn't a Jensen, or Radial, but it's good, smooth, and broad. And, very cost effective when you need a solution. It's small enough that a couple tossed in a gig bag don't eat up too much space, Robust enough you can take it on the road. Easy enough to deploy, that it can be your go-to. For Broadcast, when setting up phone systems, which can be a nest of buzzes, ground loop hums, and assorted noises, the perfect quick solution when you're under the gun to get the broadcast on the air. Live shows, in a venue where regular Edison can be iffy, Problem solved. Keep a couple in your pocket. Again, not the perfect transformer. Rupert Neve wouldn't be integrating them into his designs. But, for fast, quality, reliable solutions...put it into your kit. Several of them.
