Problem with Behringer 315D speakers.

[Blazer1511]

I recently purchased 2 Behringer 315D speakers for my mobile DJ business. The setup I was running previously was as follows: Behringer Xenyx 1024 USB mixer, one American Audio PXW18P sub and 2 American Audio XSP-10A PAs. When I attempted to substitute the Behringers in place of the American Audios I got sound to the Behringers but the sub would run at a very, very low level. The signal light on the back of the sub would not light up and the signal light on the front of the sub would flicker just a little bit, if at all. It seems like the sub is not getting a full signal. After checking all connections, I then replaced the Behringers with the American Audios and the sub worked perfectly as it did before. I'm wondering if anybody has ran into this problem before and if so what can I do to resolve the situation. Thanks!

Thanks for your question Blazer1511.

The first thing I would double check is your signal path. Assure that your mixer's Main Mix output is connected to the input of of the subs. I assume you are utilizing the internal crossover of that subwoofer. It looks like there is a Crossover output and a Bypass output on that American Audio sub. Did you try both outputs? What is your crossover frequency set to? There's really no reason these speakers should operate any different from the American Audios. I believe you might just have some wires crossed or the crossover frequency set improperly.

Essentially, the output from the crossover shouldn't be influenced by what type of speaker you are using. Check your connections one more time and let us know what you find!

Thanks, Andrew! I'll double check everything tonight and see what I can come up with.

Okay. I checked the signal path. Running from Main Mix into the sub's input. Ran signal out of the sub thru both outputs (thru output and then high pass) into the Behringers. Still no change as far as getting full signal to the sub (still getting signal to Behringers). As far as crossover frequency, where would I change the setting for that? Thanks again for your help!

The standard crossover frequency is usually between 80 Hz and 100 Hz. I listen for the kick or bass drum on a few different songs and adjust it by ear. Listen for the kick drum being "boomy" and set it according to your desire.

Can you test to see if the Main Mix output works directly into the B315Ds? Logically, it doesn't make sense that the output to the B315D should influence the signal your sub is receiving.
