Standard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High-impedance input; higher output level than a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out -4 dB). Key Features Active 1-channel DI box with premium balancing transformers 10Hz –40 kHz frequency response, high dynamic response -30 dB input attenuation, switchable Ground lift switch for each output Balanced mono summed output Can be powered with 9 to 24 V DC mains adapters or phantom power Technical Data Product type: DI Boxes Type: Active Inputs: 1 Input/Output Connectors: 1/4 Max.
