UNiKA PRO-248
UNiKA PRO-248 is a professional active two-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-248 uses the 48 V phantom power of the microphone preamplifier, no batteries or other power supplies are required.
INPUT CH1 and CH2: TRS connectors allow connection of a variety of unbalanced and balanced sources to the PRO-248. Typically these are high impedance signals from instrument pickups, but the PRO-248 can also be used as an ISO input for line level signals. One stereo or ztwo mono devices can be connected.
