Pyle Ultra Compact Phono Preamp - Mini Turntable Preamp for Audio - Guitar, Microphone - RCA Input/Output for Record Player - Receiver - Amplifier - PP444

Read in entirety: I purchased a Technic turntable, old-school, have a complete zone home ent. system, using sonos as well as wired speakers with the HTD control module and amp. I hooked up this system myself, I am very tech savvy, takes alot to stump me...Now that that's out of the way.The turntable I purchased used is a mid to high grade Technic, came with a Pyle preamp that had no ground, turntable did not come with ground wire either, this is important, noted later.I initially connected the turntable to the preamp "in" that I had, not this new one, with no ground, then connected the preamp "out" to my receiver "in", then receiver "out" to my controller "in", no sound and loud annoying hum. I then tried to connect the preamp "out" to my sonos connect "line in" bypassing the receiver, same results, then tried connecting directly to my controller, same results.Researched, completely baffled, did I lose my techi touch? Scratching head, discouraged, defeated? Not on your life!I ordered a factory ground wire for my turntable and this preamp with the ground connection, then...I started all over again preforming the same connections as before but with the turntable ground wire connected, initial loud hum happened, then went away and had dead silence. Scratching head again.NOTE TO THOSE CONNECTING TO RECEIVER OR OTHER THAN AN IN WALL HOME SYSTEM... the most important thing to know, if you connect this preamp and put it too close to an amplifier or other high electric output it will still hum, this needs to be seperated a little bit, keep reading.My final setup is removing my receiver altogether, turntable to "in" on preamp, preamp "out" to sonos connect "in", sonos is connected to controller, ground wire connected to turntable and preamp. Placed preamp next to turntable on shelf above controller and amplifier, only about 6 to 8 inches apart but shelf appears to add a buffer. Everything on, no hum, but no sound. Tilting head questioning again, more googling.For my system, my controller controls the volume up and down not the music source, I had to put the sonos sound level for the line in to 10, auto delay to medium, autoplay on to include grouped rooms but turned off autoplay volume, this makes it so music will start once the needle hits the vinyl, line out level is pass through because I have a controller, and wala, sound. Now it will play on my sonos without me using my HTD controller but it won't hit my wired speakers in group until I turn that on but when I do it all works.IMPORTANT GROUND WIRE and PREAMP NOTE... If you have a turntable that has a built in preamp you should not need this, read up on your system as some newer ones have one built in and it's a matter of flipping a switch on the turntable. If you have an old school turntable you are trying to connect to newer technology you most likely will need this AND the ground wire, the ground wire helps to disperse the bad waves to a non audible source and keeps the good sound going where it should, to simplify the why, if you do not ground your turntable you could still have a hum.Some turntables have a ground screw or plug in connection located where the red and white are plugged in, some ground points are on the under bottom of the turntable, I've seen some where you have to open the turntable to get to it, research your turntable if it has a ground point, if it does anywhere and you still have a hum, connect a ground and place the preamp away from high electric output sources.Enjoy your tunes.Good luck!

I purchased this unit to allow me to connect my turntable to a newer stereo system. I needed a pre-amp for the turntable and this works beautifully. The sound quality is very good (only some better speakers could improve it) with no distortion. The volume control is on the main stereo system. I haven’t noticed any heat issues even after using the turntable with the pre-amp for several hours. Great solution without a big price tag!

Seems to work well . The devise is easy to install & use .I had to ground my turntable though , which was pretty much a given.4 Stars because I'll wait & see how it holds up , no 5 stars right from the start .

Easy set-up, works fine

So, as others have mentioned, there is no power switch, but that really isn't a major issue. I purchased the PP444 so I can take an old turntable to friends and family activities. I plugged the preamp, my small Pyle amp, and my turntable into a switched power strip. This is an easy work-around for the no power switch on the preamp. Anyhow, I grounded the turntable to the preamp and everything worked fine with no hum or other distortion. I'm quite satisfied with the unit.

Bought this to go with my first turn-table and returned it within a week! It turns out records are not pressed with a flat EQ, an industry-standard equalization is applied as a form of compression. Then a phono pre-amp is supposed to apply the mirror RIAA Equalization, to offset that and bring back the original balance. This pre-amp does NOT apply RIAA Equalization, making records virtually unlistenable, which calls into question why this product exists (and still exists 10 years later).In addition to being unlistenable, there was a very loud hum in the line. Worse, if I turned up the the volume a little this Pyle was clearly receiving an FM radio station. I replaced the Pyle with a "ART DJPREII Phono Preamplifier" that has worked well ever since.FWIW that was 2014 and I'm just typing the review 10 years later, since Amazon asked. However this was memorably a Pyle of shi* and probably the only thing I've ever returned to Amazon on the basis of a flawed design making it useless for it's intended purpose.
