Product Information

About this item

• Package Includes: (1) MDB-1A Active Direct Box DI Box, (1) Rockville RPAK Charcoal Stylish Durable Backpack Bag w/ Padded Laptop Pocket
• Active DI performance (MDB-1A): Active circuitry delivers higher headroom for ultra-low noise, with a high-impedance 1/4" input and thru, balanced XLR out with Ground Lift, plus Low Cut, Polarity, and a -20dB pad for hot sources. Merge switch sums stereo to mono. Powered via 48V phantom. Spec highlights: 20 Hz-20kHz response, 90dB S/N, 130 dB dynamic range, and 0.02% THD @ 1kHz for clean, transparent signal.
• Connection flexibility and control: The MDB-1A equips you for stage or studio with female 1/4" unbalanced input (330k-ohm impedance) and male XLR balanced output, plus 1/4" unbalanced thru to feed an amp. Tame hum with Ground Lift, tighten tone with Low Cut, and correct phase with Polarity. Front LED indicates Merge on/off. Built-Like-A-Tank construction with thick steel, impact-resistant corners, and durable jacks stands up to heavy gigging.
• RPAK backpack utility and protection: Charcoal RPAK features a main zippered compartment sized 15" W x 21.75" H (extended) or 15" W x 18" H (folded), a padded laptop pocket with Velcro for up to 15" devices, padded/adjustable straps, a hidden side zipper pocket, and two open side pockets for drinks or an umbrella. Durable nylon fabric keeps contents protected between studio sessions, rehearsals, and everyday carry.
• Bundle efficiency for musicians and techs: Pair the MDB-1A with the Rockville RPAK to travel light and stay organized. Safely stash the DI and cabling in the backpack while routing clean signals to mixers and front-of-house. Ideal when high-output instruments need extra headroom and noise control, or when summing stereo sources to mono. Compact 1.5" x 3.4" x 5.8" unit weighs just 0.8 lbs to minimize carry load.
