•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 signals into unbalanced outputs

•Converts unbalanced +10dB DJ mixer signals to balanced mic 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-1, thus eliminating the need for a direct box on each keyboard.

•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 hum problems

•Rugged, roadworthy all-steel construction for years of continuous reliability
