unbalanced outputs from XLR and ground hum/buzz

Idk about the buzz, but the latency should be affected by the different length. My speakers had problems if my white cable was longer than the red.

It's not latency issue. The output level of left channel is lower.

i have also tried different XLR cables of the same length as well.

@john > Unless there was an impedance problem with the cables, or the source tracks are not even, the levels should be balanced between L and R.  If you reverse the cables does the audio drop go to the other side?  What about when you used a different pair of cables?

The buzzing could simply be a ground loop or interference from your computer - if it's a laptop, try disconnecting the power supply to the laptop and see if the buzz goes away.  You may need to try a ferrite-core on the USB cable or get a DI box to run between the controller and the speakers.

The source audio is fine. The VU meters on the controller are at the same levels. I still get the buzzing when running the laptop on battery. I am going to try to put everything on a power conditioner to see if I still get the buzzing.

I tried different pairs of cables, and even reversed the cables and it dropped to the other side. I contacted support, and they told me to take the controller to my local Pioneer service center. It is still under warranty (bought Mar '11).

If all else fails, I will send the unit into Pioneer for repairs.

Yeah, I've had a hum in my laptop audio. When I connect DJ hurcules 4+6, No hum. When I connect Ergo, the hum is there. Really annoying. Nothing fixes this... Not even a ground loop isolator :-(

@Jamey > Have you tried unplugging the laptop power supply?  Does it disappear then?

So I went to my authorized repair shop and they replaced the output sound board. It was working fine for a few gigs, and then again, it went out. This time the right XLR output signal is lower than the left XLR output signal. I emailed Pioneer and asked if I could get new replacement unit, but they said I have to send it back into the repair center.

Has anyone else had issues like this?

I hate to say it, but I may just sell my controller after repair and go with the Numark NS6

Is there any known issues if I only use one XLR output in mono that may be causing the XLR outputs to go bad? I usually run my setup mono out to sub then to my tops.

@John > No, that shouldn't cause any issues.
