Phono Turntable Preamp - Mini Electronic Audio Stereo Phonograph Preamplifier with RCA Input, RCA Output & Low Noise Operation Powered by 12 Volt DC Adapter - PP999

I will start off by saying I am not an audiophile or a music expert in any way. But this thing works and solves my problem I need to get an old Technics turntable to my newish Denon AVR without a phono input. And it does just that. I have been using it for at least 6 months now and it still works good. All you have to is plug the left and right into it and screw in the ground wire from the turntable to it and then plug the power cord in the wall. Then connect the other left and right into an avr or a powered speaker. Everything that plays through it sounds fine and clear. No static or weird sounds. Is it a vacuum tube fancy pants thing? No. Do I care? Also No.

This gizmo works exactly as advertised. I have a 1971 Sansui SR-2050-C turntable that has been sitting in storage for 37 years. (Yes, it needed some lubrication maintenance.) My old amplifier with a "phono" input is long gone and my current Yamaha RX-V385 amp has only HDMI and audio visual RCA inputs. I tried plugging the turntable into the red and white AV RCA plugs and was only able to get a very faint sound at max volume. Research showed this Pyle PP999 pre amp unit as a solution. The price was right so the next day Amazon had it on my door step. It was simple to connect and the power cord was long enough (about 30 inches). Everything was clearly marked and the instructions weren't even needed. Truly a plug 'n play setup and it works like a champ. Plenty of volume now. I would definitely recommend this unit to anyone in a similar situation.

This phonograph preamp really does the job it sets to do well. It does not alter the sound in any way, just amplifies to a line-level input; I use it with a line input on a stereo from 2005 and find that I need to have its volume on the stereo set twice as high as any other input (tape, CD, radio) but makes it usable. The lack of volume isn't a big deal though as that provides wiggle room if I were to add a tube preamp to adjust the sound as well, which often those can increase volume to bring it up to the other line levels. The ground works well and there is no hum from the turntable at all. The construction seems very solid, but you can tell cost-effective measures were taken to keep it affordable while keeping the build quality great. For example I initially had the left and right channels reversed when I hooked it up because the colors on the phono input were incorrect; the same RCA plugs were used on each side and that made the colors backwards on the input side... they are labelled correctly on the case of the unit so follow the label on the case instead of the color! Also the ground screw is not a thumb screw as pictured but a very stiff hex screw; I needed to use a pliers to actually move it to get the ground wire secured in place, but once it's done it's done. I do like that the unit itself is silent, does not get warm in the least, and has no lights to distract you. An on-off switch would be a nice addition but I solved this concern by having it on a switched surge protector (from Trickle Star) that automatically turns on when the stereo turns on. All in all a good product at a very good price point.

Great product! Worked instantly!

I didn't realize I needed a turntable pre-amp to connect my vintage turntable to my modern tuner. I couldn't figure out why I got no sound even at full volume. I did some quick research and ordered this item. It took less than a minute to hook up and the issue was solved. It works great. Make sure you have an additional outlet as it must be plugged in. I certainly recommend this product.

Very audible hum... Even with a ground attached from a phonograph there is a very loud audible hum. There is no ground on the power adapter and the sound quality is ok, there is a noticeable to me; high end cut on the sound that does make it through. There is no adjusting this preamp. It is built well, solid metal construction. It's a black box with connectors and labels for power, in/out, and a ground for the phono. That's it.

I recently upgraded to a new turntable and wanted to give my old turntable (which doesn’t have a built-in preamp) to my son. The plan is to use the Pyle preamp to connect the turntable to a pair of powered budget speakers. The turntable and cartridge are in the $500 range, and this preamp (nor the budget speakers) will probably not be the best match for it. He can upgrade to a proper amplifier and speakers later if he wishes. The turntable was previously connected to a modern Marantz stereo amplifier, but I’m not expecting the Pyle to compare with that. I have a vintage Pioneer receiver and used that to compare the performance of the Pyle against the phono stage on the receiver. This review is based on that comparison. The turntable and the Pyle preamp are both connected to the grounding terminal on the receiver so that they share a common ground. The output from the Pyle is fed into the receiver through the tape input. The turntable is either connected directly to the phono input on the receiver or the Pyle depending on which one I am evaluating. There is a hum when using the Pyle. Because it is sharing the same ground as the receiver, I don’t think it is a grounding issue. The hum is not loud and is not noticeable when music is playing but is noticeable in the blank spaces between tracks or when the stylus is lifted off the record. As for the audio quality, the Pyle was almost as good as the receiver, which is pretty darn good for the price point. The bass was a bit muddy, but that might be due to the aforementioned hum. There was not much to complain about mids and highs which I felt was a tad better on the receiver’s phono input. The phono preamp has two things to do: amplify the weak signal from the turntable cartridge by about 1000-tmes to the standard line input level, and apply RIAA equalization. These two steps can introduce noise and distortion to the signal, and I think the Pyle did a very decent job in controlling that. If your amplifier or powered speakers are far from the turntable requiring extra long RCA cables first connect the preamp directly to the phono cable from the turntable and run the long RCA cable between the preamp and the amplifier/powered speakers. The phono cables are shielded to isolate from outside interferences and regular RCA cables typically are not. If the long RCA cable is used between the turntable and the preamp it will happily amplify (by about 1000 times) any interference picked up by the RCA cable and you will hear it. This is in no way an audiophile quality preamp. It is almost as good as the phono stage on a 50+ year old receiver with old worn transistors and capacitors. A good phono preamp would cost well over a hundred dollars, and this only cost me seventeen dollars! I think the Pyle is doing a stellar job at this price point.

We needed one of these in order to make the old turntable work. Plugged it in and VOILA now everything works perfectly.

It works very well for my player, no hum or other static disturbances.

Me sorprendió el sonido que salió de este preamp phono. Honestamente no esperaba mucho por su bajo costo, pero haciendo pruebas de comparación auditiva con circuitería de preamp phono de buen equipo vintage, no ha quedado mal.

I didn't even know what a preamp was until I bought a used record player that I plugged into a unit with no PHONO input (just AUX and TV). The audio was very quiet and weak. This preamp did the trick to bridge the 2 devices and allow proper, clean audio levels. Now I can start my vinyl journey! Easy setup, quality build, and functions perfect. Recommended!

Cheaper alternatives than repair the build in phono stage

Un excellent rapport qualité prix. Une qualité plus que suffisante pour mon usage (pré-ampli pour platine vinyle). Attention au vendeur, le produits était arrivés dans un sac poubelle, l'emballage d'origine était défoncé, et le produit final légèrement abimé.
