Question about RME Intelligent Audio Solutions RME Hammerfall DSP RPM Phono/Line I/O -Mac/Win- : PCI-Based Audio I/O Sound Card
I get buzzing sound in my speakers when I switch to the phono stage on
my receiver. I noticed that it is related to the dimmer switch
controlling the track lighting in my living room. When I turn off the
lights buzzing sound disappears. Right now I plugged my turntable into
the contact furthest away from the dimmer, it helps but the buzzing
sound is still there. Is there a piece of equipment that will eliminate
Please advise. Thank you.
It is a grounding issue with the turntable most likely. Some turntables came with a ground wire that you attached to the receiver. You can also try a power strip that has a line filter incorporated to get rid of the hum. Check the local stereo shoppe to see if they carry them.
You may also want to replace the audio cable that connects the turntable to the amp with a good quality shielded cable. If it has bad shielding it will pick up electrical interference and even radio interference as well.
Turntable inputs on receivers have a preamp built in and the gain for each type of pickup is different. The pickup is either ceramic or magnetic and if I remember correctly, the ceramic pickup needed more gain than the magnetic one. The preamp will definitely make a ground hum a lot more audible.
Cheers and good luck.

Tips for a great answer:
have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
make sure you have an earth ******** before touching any parts inside your computer
hope this helps
