Polsen XP-4 4-Channel Signal Booster

Ideal for studio or stage use, the XP-4 Signal Booster from Polsen is a four-channel mic booster that safely adds up to 25 dB of clean, transparent gain for passive dynamic and ribbon mics. Running on simple 48V phantom power provided by most interfaces and mixers, the XP-4 can even provide a boost for powered condensers, delivering an excellent solution for noise-free signals over long cable runs, avoidance of noisy preamps when tracking quiet instruments, and an improved signal-to-noise ratio without excessive coloration.
