## Overview

The Rockville PPA52 Preamp Pro is a professional-grade 1U rack pre-amplifier designed for superior audio performance. It features Bluetooth and USB connectivity, multiple input options, and a built-in 3-band equalizer, making it perfect for both recording and live sound applications.

## Description

Top quality low noise preamp The main job of a pre-amp is to control the signal going to your amp or powered speakers. They are the first part of your signal and a good pre-amp is essential to having great sound quality. Having a separate pre-amp that specializes in that one job will give you better sound quality than an all in one receiver or integrated amplifier. Inputs and Outputs What makes our model different from some of the standard ones on the market is that we carefully chose the inputs and outputs. We have (3) RCA aux inputs that will support any audio device. We also have a Phono RCA to support turntables. There are (2) ¼” inputs that can be run in stereo for any pro audio devices. There is also a front combo jack with selectable mic/line. The mic preamp is extremely low noise. Recording interface Yea, we did it. We added a USB computer interface! Yes, this will work with any of your favorite DAW’s such as pro tools or Ableton live. You can record the final mix into one stereo channel in pro tools or any other DAW. Anything being played through the pre-amp will be recorded including the microphone inputs, as well as any source you are playing. It will be summed to one stereo channel in your DAW. You can also use Ableton live or any other software to play music as an input device on the preamp. The interface is 2-way and you can use it as an input playback device or as an output recording device. Bluetooth and USB playback We wanted to make this product extremely versatile, so we added Bluetooth audio playback. This is perfect for home audio use as well as for some pro audio applications in between sets etc. There is also USB playback so you can play back audio saved on a thumb drive. Amazing controls There is a high quality 3 band EQ so you can adjust and fine tune your sound. There are bass, mid, and treble controls. Also, we added a low-cut crossover which is great if you will be using a subwoofer so that you can cut some lows out of your main speakers. The mic/line input on the front has its own volume control and can be used at the same time as any of the other sources like Bluetooth or RCA.

## Questions & Answers

**Q: Would i run my outputs on this to my eq input xlrs and eq outputs to amplifier inputs ?**
A: You can do that, but you can directly go to a power amplifier, as this pre-amp has already options to adust bass and treble

**Q: Would i run my outputs on this to my eq input xlrs and eq outputs to amplifier inputs ?**
A: Yes, that would work.

**Q: How do i hook it to my amp?  my amp as rca inputs, not xlr.**
A: I'll answer the question as if your 'amp' is a stereo amplifier.  I wouldn't hook it up to a guitar or bass amp (not that it can't be done) for fidelity reasons.

One way is to get two impedance matching transformers (or line matching transformers) to go from the low impedance balanced signal (the XLR connectors) to high impedance (most microphone transformers go to 1/4" male phone) and then use the correct adapters to go from 1/4" male phone to RCA.  I tried to do this with one channel of the Rockville using a microphone line matching transformer and I noticed high frequency loss (the music sounded muffled).  The PA cabinet I use has both XLR (which is what I use) and 1/4" inputs.  For the test I used the 1/4" input on the PA cabinet from the line matching transformer.  I did an A-B test a couple of times and there was too much high frequency attenuation for my taste.

You may be able to wire the XLR outputs directly to RCA jacks, but I'd be hesitant to do that myself.

Another, albeit more expensive ($99 plus or minus), possibility is to get a two channel mixer with XLR inputs (like Behringer or Mackie or ???).  Some mixers have RCA tape outputs that you could use; you could also use the mixer's 1/4" outputs and convert to RCA.

Good luck!

**Q: how many watts per channel**
A: This is a pre-amplifier, it is only conditioning and swiching audio signals, to connect it to soeakers you will need a extra power amplifier

     The PPA52 preamplifier has worked flawlessly.  Sound has been good, and the interface is easy to use.  My only complaint is the short bluetooth range so far.  The preamp is moved from place to place as the main head unit for my backyard theater rental business, and my customers and I have been extremely pleased with the sound and ease of use that it offers.

    Completely disappointed with this product.
  

*by A***C on Reviewed in the United States on August 26, 2023*

This product performed horribly. Not able to adjust bass, mid, or treble. The only sound from this device was a loud hissing noise...
