Connect your guitar or bass directly to your mixer without losing tone due to impedance mismatches, long cables and cycle hum * Converts any unbalanced line-level signal to balanced mic-level output * Provides impedance and signal matching for the direct connection of instruments to amplifiers and mixers * Allows the use of long cables without losing high frequencies * Thru/out jack lets you send the unbalanced signal to an onstage amplifier while the balanced signal is routed to the mixer
