Continuing in our series of videos about subwoofer setup, Axiom Engineer Andrew Welker gives us an idea of what you need to know about subwoofer connections. It can be confusing – XLR, Line Level, RCA . . . what’s the right one to use?
Andrew Welker: Today we’re going to talk a little bit about connecting a subwoofer to a receiver. Connecting a subwoofer is not very difficult, particularly as most home theater receivers now have dedicated Subwoofer Outputs on them. The first thing that I want to mention is that before you make any connections it’s a good idea to make sure that the power is off to the receiver and the subwoofer. You’re not necessarily going to damage anything, but it can cause some startling bangs and noises if things are not right. Log in

There’s something so exciting about unboxing a new home theater system. You can almost smell the popcorn in the air . . . but once you’ve got everything in your room and you have the front speakers, center channel, and surround speakers in their designated space, you’re left with the one speaker whose placement isn’t immediately obvious.

Q. Some expensive A/V preamp-processors and power amplifiers offer “balanced connections.” And the new Axiom EP600 and EP500 subs also have them. What are they, and are “unbalanced” connections inferior to balanced? What would I gain in performance using balanced cable? – J.C.
Used almost universally in the world of recording studios and professional broadcasters, balanced cable use a three-wire cable fitted with very secure and solid “XLR” connectors (sometimes called “Cannon” connectors). The three-wire balanced configuration is composed of an outer shield surrounding two out-of-phase inner wires that carry the positive and negative portions of the signal. This enables running very long cables–hundreds of feet if necessary– between amplifiers and preamps or between microphones and a mixing console without picking up hum or interference and without significant signal loss.

Q. How do I connect the subwoofer to my A/V receiver? I have one cable. Do I plug it into the subwoofer’s left or right input, or both?
A. Use either the left or right line-level RCA jack on the subwoofer. You don’t need to connect it to both, because the inputs are “summed” to mono inside the sub. Connect the remaining RCA male plug at the other end of the shielded coaxial cable to the single “Subwoofer Output” jack on your receiver. It might also be labeled “LFE Out” (Low Frequency Effects) or “Sub Out.” That’s it! Subwoofer connection made easy! Log in
