The PP999 is perfect for bringing your studio equipment's phono-level output to a more suitable and manageable line-level output. It'll take your audio signal, amplify its strength and prepare it for further processing by your receiver or amplifier. Preamps technically provide voltage gain to your desired equipment and are key to assisting the signal source. The ultra-low noise audio conditioning circuitry allows the preamp to boost audio to levels that are more manageable for various types of audio equipment. You'll find it easier to adjust the recording level volumes of different sources and instruments alike. You should position your preamp close to the source to reduce unwanted noise and interference. Preamps can sometimes come built into the stereo equipment, but if that's not the case, the PP999 is an easy install, wise choice and great addition to any musician or producer. Take your sounds and audio production skills to the next level with the PP999 Preamplifier.
