I have a Harmon Kardon amp and have recently hooked up a turntable to the Cd input.I had to use a small Radio Shack preamp inline to boost the signal.The preamp has a ground which I attached to the amp ground screw.The turntable,however is a turntable used to convert albums to wav or mp3.It has no ground but has a usb port and a gain knob,as well as a switch indicating “RCA phono line” and “RCA line” .At a high volume there is a distinctive buzz .When I put the preamp in a slightly different position or touch my finger to the RCA jacks the buzz gets better but never goes away.Any ideas?Peter
You have to connect red & white cables from turnable to phono input, not to any inputs on receiver.

ART DJ Pre II Phono Preamp $33.96 The ART DJ Pre II should be in every DJ’s gig box! Vinyl records have drawbacks. Bass compensation can be needed during playback. Records produce a certain amount of hiss, and magnetic cartridges produce a weak signal. A separate RIAA preamp is necessary when you are connecting a turntable to a mixer that does not have one built in. The ART DJ Pre II features an RIAA-type phono preamp circuit with full patching facilities for connecting a phono turntable and mixer. The DJ PRE II (formerly named the Phono MicroPRE ) acts as an interface between your turntable and your audio recording / playback system. The analog input capacitance can be switched between 100pF and 200pF to optimize your phono cartridge response. A switchable low cut filter removes turntable rumble while leaving the audio pristine. The front gain trim control and signal/clip LED allow you to optimize the preamp’s gain for a wide range of input sources. The built-in low noise phono preamp circuitry is highly accurate and precisely conforms to the RIAA standard. The line output jacks are low impedance and can be used with any sound card. Housed in an all aluminum black anodized case, the DJ PRE II can be powered by a wide variety of external supplies. If you need to amplify and EQ your vinyl records to interface with your audio workstation, sound card, home stereo system or main monitor system, the DJ PRE II gives you flawless audio reproduction in a rugged and reliable package. ART DJ Pre II Features Dual RCA-type inputs Dual RCA-type outputs Ground terminal Power: 12V DC (Adapter included) ARTcessories Series Overview Creative audio solutions in cool little boxes. ARTcessories are taking the audio world by storm and quickly becoming a popular brand with musicians, DJs and studio engineers everywhere around the World. Split, combine, mix, power- you name it.
