I have used it with the Presonus rackmount system and JBL subwoofers/networks. Here's how I used it: I sent an AUX stream to this unit and then split it to each of the subwoofers. So I could only send low parts (bass drum, toms, bass, keyboards) to this channel. This kept all low frequencies off the grid, which really helped keep the sound very clean and crisp. No more mud about vocals and guitars. I highly recommend.
