Active DI Box with Noise Filter for High to Low Impedance Conversion

The CHORD DI-A1 Active DI Box is designed for converting high impedance instrument outputs to low impedance line signals, making it ideal for direct connection to mixing consoles. Featuring an internal buffer amplifier, it boosts the signal to prevent loss over long cable runs. The unit includes a 3-way pad switch for level matching and a Ground-Float-Lift selector for signal ground isolation, with options for RF/mains filtering.
