Rockville PPA20 Preamp 11V 1U Rack Mount Professional Pre-Amplifier, Phono Input, XLR Outputs, 3-Band EQ, for Home Audio and Studio Recording

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.
