DI02 is a compact, phantom powered direct-inject (DI) box, that provides the impedance- and level-matching required when a high-impedance music instrument signal must be connected to a mixing-console's microphone input.
DI02's high impedance input - brought out on two paralleled ¼" jack connectors for easy line signal linking - and its symmetrical, low impedance output, insure that almost any high-impedance signal can be tapped and fed to a long microphone line without loss of signal quality.
To allow a wide input level range, the DI02 is equipped with a 2-position gain switch.
Generally the -20 dB position is used, allowing signals of up to 30 dBu to be fed into a microphone input accepting a 0 dBu input signal, but some low level signals may require use of the 0 dB position, where the output noise from the DI02 is below that of most microphone inputs'.
DI02's 2.5 mm rectangular aluminum enclosure guarantees a long life on stage and allows easy packing of any number of units for transportation.
