UNiKA PRO 148 - Single active DI Box

UNIKA PRO-148

UNiKA PRO-148 is a professional active single-channel DI box that connects electric and electroacoustic guitars, basses, effects pedals and other high impedance sources to the balanced microphone inputs of a mixing console or external microphone preamplifier. Since PRO-148 uses the 48 V phantom power of the microphone preamplifier, no batteries or other power supplies are required.

INPUT: XLR + TRS Combo allows you to connect a variety of unbalanced and balanced sources to the PRO-148. Typically these would be high impedance signals from instrument pickups, but the PRO-148 can also be used as an ISO for line level signals to avoid hum and noise.
