The Di2 Mk3 from LA Audio is a single channel, active direct box, suitable for driving long cable runs typically found in larger venues, without level loss. The DI box is housed in an extruded aluminum case and can be powered via two, 9V batteries, or by phantom power from a professional mixing console.
Disconnection of the input signal causes automatic battery shut down, extending the battery life for up to 300 hours. The presence of phantom power is also automatically detected, further extending battery life.
A Link input allows the speaker output of an amplifier/speaker combo to be directly sent to an input of a mixing console. This preserves all the tone generated by the amplifier and speaker, including EQ and distortion. For a clean signal, the instrument need only be plugged directly into the Di2 Mk3.
