## Description

The Rockville PPA20 Preamp Professional 1U Rack Mount Pre-Amplifier provides precision audio control and reliable connectivity for home audio, studio, and live sound applications. Its 3-band EQ (bass, midrange, treble) allows you to tailor sound with clarity, while versatile inputs and outputs accommodate a wide range of gear including turntables, CD players, mixers, recorders, and powered speakers.Designed with advanced sound customization tools, the PPA20 includes input source switching, tape monitor, mono/stereo mode, mute/pad (-20dB), L/R balance, and loudness compensation, which boosts bass and treble response at lower volumes. A low cut filter helps eliminate subsonic noise from vinyl and subwoofers, while the ground lift switch reduces hum and interference for cleaner output.Technical performance is equally strong, with a frequency response of 5Hz-30kHz, THD of less than 0.02% (mic), less than 0.04% (phono), and less than 0.01% (aux/tape/CD/tuner). Input and output impedance are optimized for professional integration, and efficient 15W power consumption ensures consistent operation.Compact, durable, and rack-mountable, the Rockville PPA20 Preamp is a powerful solution for audiophiles, DJs, and professionals who demand clean, flexible, and accurate sound control in a streamlined unit.

Review: Awesome preamp with XLR output - I have a Carvin 1500 watt amp and always wanted to use it as a home stereo (not theater....just for stereo music) amplifier...the Carvin has a 1/4inch ins and XLR inputs which are balanced. I wanted a preamp to have XLR output to use the very nice XLR input on the amp...which makes a huge difference in sound quality and noise cancellation when using XLR (balanced cable) and you can push the amp higher with cleaner sound, I did read some reviews about noise and some non functioning dials on this preamp...but for the price I decided to take a chance and I am glad I did. The sound quality blows away my Integrated amp (100 watts per channel) - and good luck finding a preamp for this price full stop! I did find one preamp with XLR outputs for a mere $4500!! Decided I was going to take my chances with this one! Also as a side note the equalizer function is clean and accurate, AND the loudness button really works well. One last caveat was that I can use the MICROPHONE input to plug in my guitar directly and play along with the music for learning a song or just jamming along....I am assuming you can actually use this as a sing along Karaoke machine to your favorite music is you are vocally talented (I have been banned to even sing in the shower which I think is rather cruel! so no...I dont have a microphone!) - anyhow....if you need a preamp, this is a good one...it has RCA in and out...AND you can plug your own equalizer to it if you want before sending out to the amplifier....I am assuming that would allow you to equalize on both the pre amp AND the equalizer for major sound modification. The only thing I wish the pre amp had would be a lighted face, but I am sure that would send the price up significantly....Hope this was helpful
Review: Great Preamp! - Awesome preamp! I wanted to use it as a stereo receiver to hook up to my cassette deck and it works really well. I love the eq and all the settings on the front panel, very useful. I also love the fact that it has so many phono inputs in the back, that way you can hook up multiple things at once.

## Questions & Answers

**Q: My speakers are speakon so how do i use this amp to run my speakers to run my speakers as a output?**
A: You need an amp with speakon outputs like the beringer kvm 750. That amp is 750 watt and two channels, you can get it from Amazon for 150.00 . It's a good solid amp with speakon outputs for your speakers.

**Q: Can i take a regular 3.5 mm aux cord and plug it into the input and take a 3.5 mm aux cord and plug it into the output for my headphones?**
A: Don't see why not.

**Q: Do i i need a better eq**
A: Not necessarily. If you’re more recording inclined, maybe. The dynamic range should suffice for most everyday listeners.

**Q: Are the xlr outputs line level?**
A: Yes they are because it's a preamp, you can get XLR to RCA or 1/4 in mono left and right on the other end cables to plug into power amps or go XLR to XLR
