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.
The XP-4 features four locking XLRM and XLRF connectors for its I/O, offering solid, interference-free connections that resist accidental tugs on a cable in studio and live environments. The XP-4 is rackmountable, making it easy to fit into a 19" equipment rack for transport and demanding studio or stage applications. Constructed from rugged steel, the XP-4 is engineered to withstand impacts during the most rigorous of applications.
But the booster doesn't pass along phantom power, so it's perfectly safe to use with delicate ribbon microphones. Battery-powered microphones and mics with their own power supply are also compatible with this signal booster.
