Product description

ART Dual Active Direct Box is a two-channel active device whose main task is to symmetrize the signal. The DI-Box has a very wide frequency response and low noise on the output signal.

The ART dADB front panel is equipped with two balanced XLR (three-pin) outputs with an impedance of 600 ohms. Each output has assigned buttons that enable or disable the following functionalities - phase inversion (PHASE), Bessel filter (low-pass) and ground disconnection (LIFT/GND). The middle button (BATTERY POWER) is used to switch on the battery power supply (9V). If the phantom power is detected by the DI-Box, the device will immediately start using it - in this case, turn off the battery power.
The middle LEDs indicate that the battery is low or DI-Box works in phantom power mode.

The back panel of Dual Active DI-Box has four 6.3-mm jack connectors - two of them are unbalanced/balanced inputs with an impedance of 470,000 ohms, and the other two are THRU connectors. An ATTENUATOR switcher is also available on each channel - it's responsible for signal attenuation (0/-20/-40dB).

Available in SQM Rental House ART dADB is known for its reliability and solidity.
