Pyle Pro PP555 Overview

The Pyle Pro PP555 Ultra-Compact Phono Turntable Pre-Amplifier brings your studio equipment's phono-level output to a more suitable line-level output. This compact electronic preamp features a 9V battery compartment, dedicated RCA and 1/4” output connectors, a DC adapter, and more.

It takes your audio signal, amplifies its strength, and prepares it for further processing by a receiver or amplifier. Preamps technically provide voltage gain to your desired equipment and are key to assisting the signal source, whether it's a turntable, musical instrument, or a microphone.

The low-noise audio conditioning circuitry allows the preamp to boost audio to levels that are more manageable for various types of audio equipment. This makes it easier to adjust the recording level volumes of different sources from microphones and instruments alike.

This easy-to-install device is a good addition for any musician or producer whose audio system doesn't already include a preamp.

Pyle Pro PP555 Reviews

It Works Okay.

The power supply that came with it can only work with 110 Volts ac and here in South Africa we only use 220 Volts so I have to use the 9V battery option and the bad ting about that is once the battery is installed there is no off/ on switch on it. So the Amp stays on until the battery is dead or you have to take it out and install it every time you want to use it.

Poor design, don't purchase.

Tried 2 and sent both back. Only right channel worked on both. Obviously a manufacturing defect.

I wouldn't buy this again

I would give this a no star rating, but that is not a choice. I did not expect a great deal, but I did expect the product to work. Only 1 channel was operational and I did confirm that a signal was coming from the phonograph over both channels. Granted there may be flaws in any product, but I would at least expect that the company would answer my email. There was no way to phone and I followed the instructions to contact the, but after 1 week still no response, therefore I can only conclude that the poor product function reflects a poor attitude at the company. Too bad as the reviews suggested that this may be good. This in no reflects poorly upon B&H who delivered it with their usual efficiency.

I had grand hopes but didn't really think it through. It had a sturdy build quality but the grounding nut didn't, and from my more than basic understanding of electrical currents, simply cannot work unless the unit itself is bonded (connected) to a ground source. Note in the picture there are only two prongs on the DC power supply. Meaning, no ground. If your turntable has a grounding wire separate from the power cord, it needs to be ground/earth. I ended up connecting my ground wire to one of the screws on the AC receptacle which works but even then, with no gain adjustment I was left with very little volume option before the signal became distorted. Oh! ....and no on/off switch other than omitting the battery and using that switch. Sorry B&H. I just believe I'm going to have to through a bit more money at it to get my record on. You'll be okay with that, right?

Pyle turntable pre-amp

Perfect for anyone who has a magnetic cartridge turntable not adaptable to say a home theatre system. Easy hookup. However, after I powered the unit up I got a very loud, annoying hum during play. Luckily, the solution was simple. I just disconnected the grounding wire. Had it not been for this, I would have given the product 5 stars.

Great for the cost

Not too shabby. Surprisingly low noise and having the ground screw is a nice addition to the last model.

The pre- amp was for use with my turntable. It came well packed with instructions and was simple to install. The instructions showed a switch to be used to choose the power source. This switch was not found on my unit, but it worked perfectly with the 12 volt power source supplied. Unit worked as expected for a small unit and the sound was very good with no hum or distortion.

Got two, both faulty

I ordered one, it only worked with the battery, not with the AC cord. B&H Support was very efficient and nice and offered to send a new one right away (no email confirmation, but oh well). It arrived pretty quickly and did work with both the AC cord and the battery, but only one channel worked! No! Out of curiosity, I tried the new AC cord on the first preamp, and it actually worked. So it was just the cord that was faulty with that one, right? Nope. When I originally tested the first preamp, I didn't listen to the sound closely because it didn't work with the AC cord, I just reached out to B&H for a replacement. Now that I got it working, I realized one channel was working well but the other one was only at about 20% volume. Two preamps, both don't work. I have tested the cables and turntable with other devices. I can't find my original receipt at this point. I guess I give up. These things are Pyles 'o .....

See any errors on this page? Let us know



I've read that powering the unit with a battery reduces line noise. Will this unit also charge a battery while not in use?
Asked by: Anonymous
I do not think it will charge the battery. I use mine without the battery most of the time. I have not had any problems with line noise with it properly grounded. I grounded it to the grounding screw on the back of my surround sound receiver

Specifications for these Pyle phono preamp products don't make much sense: Output 2 Vpp maximum at 10 k?? Typical line inputs that this plugs into are 20k? to 50k?, and output voltage is actually more commonly stated in Vrms (2 Vpp = 1.414 Vrms). S/N ratio 70 dB? Is that unweighted or is it A, B, or C weighted? That's like saying My coffee cup holds 3. Input Sensitivity 3 mV at 50 k? (phono)? For what output level? 2 Vpp maximum at 10 k?, or what? Is 50 k? the input impedance (where the turntable plugs into it)?What is the overall gain? Not stated. From the previous input sensitivity spec, I calculated it as about 53.5dB, which is usually enough to amplify low-output moving-coil cartridges. If true, this could be the greatest audio equipment bargain in history! That's a bit hard to believe. What is the nominal input capacitance? Not stated. This is an important factor in any magnetic cartridge's high-frequency response.I get the feeling these numbers are meant to make this product look OK rather than inform buyers of its actual capabilities. Could you maybe prompt the manufacturer for more meaningful information? Maybe do the same for other products with questionable specs and descriptions? I guess that's what happens when information passes from the engineering department to the marketing department!

As a mechanical guy, I can't tell you what the overall gain is, but mine requires turning the receiver volume above normal to hear a record and in clear passages the is a lot of hiss. Not happy with it.
