i need this for my bedside radio, but the only hole i have to plug in is for my earphone. is there any other way i can make this product useful?

It might. I have mine hooked up to the outbound line on a 4 way switcher and it does the trick. But it depends on what is causing the buzzing in your situation. If an external source is causing the disturbance then it might reduce it for you somewhat. Try unplugging all electronics nearby and let them sit for 15 seconds then plug back in, that eliminates the buildup of static electricity on the circuit boards. No guarantees but it’s worth a try to solve the interference

Do i hook the ground loop isolater from my pa system to the cd changer

Hi friend, This is Audio Pass-thru and Isolate Ground Noise at the same time, So you can use it on your any sound system for audio transfer. We are not sure the devices you mentioned. Is the CD Charger a CD Player? Could you please contact us to golverydirect-us@hotmail.com for further communication? We will try our best to help you out with this question. Looking forward to hearing from you soon. Yours Sincerely, Golvery

Will this help with a hissing and electric sounds being output from my audio mixer through a stereo RCA cable to 3.5mm adapter for my speakers?

Probably not hissing. It will help with 60hz or 120hz ground loop buzz & hum.
