SGPRO Active Direct Box, Recording Signal DI Box for Musical Instruments as Guitar, Bass Guitar, and Keyboard Live Performance or Studio, 1/4" to XLR, Ground Lift 48V Phantom Powered Compact Unit

  • ENSURE GREATER SOUND QUALITY: The active direct box reduces the impact on sound quality due to unmatching signals from musical instruments with different impedances..
  • MATCHING IMPEDANCES: The direct box turns the high impedance signal into a low impedance signal for live performance, recording, or broadcasting..
  • EXTRA GAIN FOR LONG DRIVING CABLE RUNS: The active DI box is 48v phantom powered, which provides an additional gain to boost the weak output of some passive, single-coil pickups and extend long driving cable runs..
  • NOISE ELIMINATING: A switchable ground lift prevents current from flowing between the DI and the microphone preamplifier along the shielding, breaking the ground loop and eliminating this noise. It also reduces the noise from using long wires and cords..
  • PREVENT EXCESSIVE GAIN: The direct box comes with switchable pad (-12 dB) to prevent excessive gain from overloading the circuitry to accommodate the high output of active pickups and unbalanced line-level equipment such as keyboards and electronic instruments..
