I hear a lot of noise and humming from my speakers when I connect them to the main outputs on utrack 2417th October 2017 at 12:08 #29010
What type of speakers are those?
The noise level changes when you change the volume on the front panel?
Do you have that noise only on the Main out or do you have a same noise on the Headphones out and or DB25?17th October 2017 at 12:22 #29011
I use Mackie CR4 but I also check the main output using two channel s on my mixer and it has been the same high pitch noise, I checked the headphones output and it working good, unfortunately, I and not able to check the 25D-sub connectors right now.17th October 2017 at 12:25 #29012
and the noise level do not change when the I change the volume on front panel17th October 2017 at 12:52 #29013
This sounds like some grounding issue.
I mean internally the headphones and main out 1-2 uses the same internal audiobus.
If you don’t hear that noise in the headphones out that’s sounds like some issue between the uTrack24 and the receiver.
Your cable connection is balanced or unbalanced?
Do you have a chance with a wire connect the uTrack24 chassis to your receiver chassis –> does it make any difference in the noise?17th October 2017 at 13:54 #29014
I use balanced cables but I also tested it with unbalance and the results were the same.
What do you mean in the last question because I can’t understand?17th October 2017 at 14:01 #29015
You take a solid ground point on the uTrack24 (like Wordclock connector ground) you take a similar ground point on your receiver (like XLR ground on your mixing console) and you make a connection between those two point using a raw wire.
Does your receiver and the uTrack24 connected to the same power outlet?17th October 2017 at 14:37 #29016
yes all share same power outlet
