Rated 5 out of 5 by from Superb ProductI need an electronic crossover for a sound system used on a Christmas parade float. I have used a Behringer CX-3400 in the past but it takes too long to figure out what pot to turn or what button to push!This little guy is SIMPLE, easy to adjust, and I like the labels on top of the box!And it sounds good too!

Rated 5 out of 5 by from Rolls SX21 Tiny Two-Way CrossoverI bought three of these in order to split signal between: (1) a Genz-Benz Shuttle 3.0T and an EV ZXA1-Sub (one SX21)(through the GB's effects loop) and (2) two Fishman SA 220s and two EV ZXA1-Subs (from the outputs of a Yamaha MG166CX miser). They work as advertised -- but I taped the power supply inputs to the crossovers after learning the "hard way" that that's what should be done.

will this accept a stereo 1/4 plug?

What I want to do is use this to split the frequencies <=180hz to an active sub and send everything else to a stereo amp to avoid distortion from the bookshelf speakers. Will I need to buy 2 (one for each channel) or will it filter and pass a stereo signal?
Asked by: he500guy
This is a mono crossover so it only uses unbalanced or mono connectors. Two will be required for a stereo pair.
