Active DI box for converting high impedance instrument outputs to low impedance line signals for feeding directly into a mixing console. Internal buffer amplifier to boost the signal, avoiding losses in long cable runs and 3-way pad switch for level matching. Ground-Float-Lift selector enables signal ground isolation with or without RF/mains filtering.Dimensions[tab]103 x 70 x 45mm[br]Weight[tab]243g[br]Input[tab]6.3mm jack (unbalanced)[br]Outputs[tab]XLRM (balanced), 6.3mm jack through (unbalanced)[br]Input impedance[tab]>100k Ohms[br]Output impedance[tab]600 Ohms[br]Controls[tab]0/-20/-40dBu pad & Ground-Float-Lift switch[br]Power supply[tab]9V battery (PP3 not supplied), 12Vdc adaptor (optional) or 9-52V phantom power
