ART dADB Dual Active DI Box
ART dADB Dual Active DI BoxDetails
The ART dADB dual active direct box acts as two independent, high quality active interfaces for connecting instrument, line, or speaker level signals to balanced inputs. The high impedance 1/4-inch inputs are buffered and converted by extremely low noise active electronics to deliver isolated, balanced, low impedance outputs.

The dADB delivers an extremely flat and wide frequency response even at high input levels, making it a virtually acoustically transparent DI solution.
Input attenuation on each channel allows for a wide range of source signal levels. Independent parallel thru jacks allow for tapping the signal chains. A Ground Lift on each channel allows for totally separate the input and output signal grounds to isolate two systems when required, thus reducing hum and ground-loop noise.
Switchable low pass Bessel filters eliminate high frequency interference. Operating outside of the audio range these complex and effective filter circuits are primarily intended to eliminate radio frequency interference before it gets into the main system. They also effectively reduce digital computer noise making the dADB the ideal DI solution for laptops, computer workstations and peripherals when used in stereo PA applications.
The dADB's active circuitry is powered by phantom power or by an internal 9V battery when external power is not available. Low current draw (less than 7.5 mA) should provide more than 100 hours of operation with a new battery (alkaline recommended).
The compact black all steel case and active design ensure unmatched long-term reliability in Live Sound, Permanent/Fixed Install, D.J., or virtually any PA application.

The product price includes a one year warranty and 30 day money back guarantee.
However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.
The highlights of this enhanced warranty service are:
- Warranty is extended to 5 years from the date of delivery.
- Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
- Collection and delivery costs are included for the first two years
- Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
- Warranty is transferable if the item is re-sold
- Loan or replacement equipment will be provided if the product isn't repaired within 30 days
- If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
- The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount
Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.
For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.
This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.
All Products are new unless stated, and include a minimum of one year warranty.
