DCX2496 Noise/Hiss
Hi all,
I just bought a Behringer DCX2496 Digital Crossover, and had everything connected to my Dayton RS Dipole Phoenix (RS 8" & RS shielded tweeter). I only built the MTMs, not the woofers...that will be done when the RS 12" comes along.
The MTM sounds good, except for one minor/major problem.
What I noticed bothers me quite a bit. The DCX seems to produces noise/hiss. It sounds to me similar to pink noise, but at a lower dB. When I turn up my amp to "realistic" listening level, between -30 to -10dB, I can hear the hissing sound 10ft away, during quiet passages. And when I don't play any music, I hear it also. In addition, I heard some instruments being distorted on the tweeter, which I'm guessing is caused by the DCX.
When my amp's volume control is at -60 to -80dB, I can still hear the noise at about 2 feet away. Also, when I muted the input of the DCX, the noise is still there; when I muted the DCX's outputs, the noise was suppressed, but not eliminated. When I turned the DCX off or disconnect the output, no noise, even when I cranked up the amp's volume.
Monte Kay said the DCX is noisier than Linkwitz' electronic crossover. But I didn't understand what he meant until I used one. I may keep it for testing/tuning purposes, but for my final speakers, I would not want to use the DCX. I called Behringer's tech support and told him how I tested the unit. He seems to think I received a defective one. I don't think I've got a defective unit; I think this is what I'm getting for the price...a noisy digital crossover.
I don't have any amps with XLR connectors, so I made some XLR-to-RCA cables. Could this be a possible cause of the noise?
If someone has any suggestion of suppressing the noise, please let me know.
Thanks,
