Introducing the Chord DI-A1 active DI box
This active direct injection box is perfect for connecting your musical instrument to a mixing desk. It is designed for converting high impedance instrument outputs to low impedance line signals for feeding directly into your mixing console.
The unit includes an internal buffer amplifier to boost the signal, avoiding losses in long cable runs and 3-way pad switch for level matching. It also features a ground float option for ground lift with RF/mains filter, and a ground lift option that isolates signal ground without filter.
Active or passive, what is the difference?
Simply put, an active DI box requires power, and the passive does not. The passive is essentially a transformer, balancing the signal. An active DI box also includes a preamplifier which provides a stronger signal, making them ideal for use with lower-level input signals.
