## Description

DB-MKII Dual Premium Direct Injection Audio Box Passive DI Unit Hum Eliminator w/Input Attenuator to Connect Guitar & Bass,1/4'' Impedance Transformer Connector to Balanced & Unbalanced XLR

## Features

- ✅Perfect for all live sound permanent installations, club, church and practice PA systems, monitor systems, home and project recording studios, karaoke and DJ sound systems.
- ✅Enables the connection of any unbalanced audio source signal (such as from an electric instrument, keyboard–even from an amp speaker output) to any balanced input (such as that of a mixer).
- ✅Parallel Output allows simultaneous connection to 2 separate inputs (such as to an amp and mixer). Translates high-impedance instrument outputs into low-impedance balanced signals or balanced low-impedance balanced signals into unbalanced outputs.
- ✅Converts unbalanced +10dB DJ mixer signals to balanced line level signals, enabling both easier interfacing with consoles and longer cable runs.
- ✅Enables multiple keyboard setups plugged into an instrument amp to be directly input to a console mixer by connecting the speaker outputs of the amp to the console input through the DB-MKII, thus eliminating the need for a direct box on each. ✅3-position input attenuation switch (0dB, -20dB, -40dB) facilitates proper output signal levels for optimum level matching to connected equipment. Switchable ground lift eliminates ground loop continuous reliability.
