Chord DI-A1 Active Direct Injection Box



The Chord DIA1 Active Direct Injection Box was superbly created for converting high impedance instrument outputs to low impedance line signals, which in turn, are then directly fed into a mixing console.

This Active DI Box contains an internal Buffer Amplifier; boosting the overall signal, whilst avoiding degradation losses in long cable runs. Ground-Float-Lift selector enables signal ground isolation (with or without RF/mains filtering). In addition to 3-way pad switch for level matching.
