ไดเร็คบ็อก dbx Di1, Professional Level and impedance matching function, Unbalanced 1/4″ and XLR Inputs, Balanced XLR Output, Battery or Phantom Powered, Frequency response 10Hz to 70kHz, +0dB/-3dB Attenuation control

The dbx DI1 Active Direct Box. Using a 9V battery or phantom power from your mixing board or interface, the DI1 takes the high-impedance signal which comes from instruments and other unbalanced TS or XLR sources and transforms it into a low-impedance balanced XLR signal. Low-impedance balanced signals can drive long cables without picking up interference or losing high-end articulation.
