I HAVE A NUMARKKMX01 MIXER WHEN I PLUG THE RED RCA JACK IN TO THE MIXER I GET A LOUND HUM


What is plugged into your Numark mixer when this happens? Try disconnecting ALL audio inputs to your mixer, turn mixer volumes to zero and see if the hum is still present. Adjust the volume and check if the hum you mentioned returns. If it is still heard, try new cables between the mixer and amp...if not then start reconnecting inputs until the hum is heard again. It's a process of elimination but not that difficult to find the source of your problem.

I was cleaning my phone and I pressed on something and now there is music playing that i can not stop,I don't know how to stop the music,my phone is panasonic KX-T7730


Here are two methods to turn off background music, one of these should work depending on which Panasonic phone system your phone is connected to.

1) With phone idle, press the 1 key on the dial pad (turns off background music when it is on and turns on background music when it is off).


2) With phone idle, press intercom button then dial *751 on the dial pad followed by 0 on the dial pad to turn off background music(confirmation tone will be heard) and end by lifting handset and replacing in cradle. To turn background music on, press intercom button then dial *751 on the dial pad followed by 1 or 2 on the dial pad to select the background music source(confirmation tone will be heard) and end by lifting handset and replacing in cradle.

When I hook up my computer to the receiver and play music it is hard to find a point on the master volume where the music plays clearly. The music skips and i have to be very careful with the master...


Master volume control pot is dirty and needs to be cleaned out. You can do this by unplugging the receiver and turning the master volume control back and forth from zero volume to full blast a couple of hundred times to clean the surfaces and restore normal operation.

My Panasonic KX-T7730 has a humming sound when the phone is hung up. If I turn the volume down, I have to turn it up when I am on the phone.


It would play music if you had a music source plugged into the cabinet.

Without picking up the handset, press "1". Your humming should stop. It's the command for Background Music ON/OFF.
