Chord 173.291 Active DI Direct Injection Box

Active DI Box for a clear signal and interference-free connection of instruments to PA and studio mixers.

Ideal for applications requiring high signal fidelity and/or long cable runs.

The Chord 173.291 is an active direct box, used to mediate between your instruments and PA or studio mixer.

The DI box balances the input signal and ground loop to provide a problem-free transmission, even over a long distance. Thanks to a 3-stage input, the Chord 173.291 is ideal for use with all amps and mixers, and ensures a pure sound even with very long cable lengths.

A 6.3mm jack output is included for monitoring purposes.

The Chord 173.291 can be powered using regular electrical outlets, phantom power from the mixer, or by a 9V battery.

The sturdy steel housing protects the DI box from the rigors of life on the road.
