The MDB-1A Active DI is perfect for active instruments like guitars and basses with active pickups and preamps. It offers high headroom and distortion-free operation. It has a 1/4' high-impedance input and thru with a -20db pad, and a Merge switch that turns the Thru jack into a second input for summing stereo sources to a mono output. The balanced XLR output has switches for Polarity, Low Cut, and Ground Lift. Powered by 48v phantom power for maximum convenience. Enjoy ultra-low noise and distortion-free performance with its active circuitry, high-impedance input, and balanced output. The -20dB pad ensures great performance with high-level sources. It also features a Built-Like-A-Tank™ construction.

Using the Mackie MDB-1A Active Direct Box is easy. First, connect your instrument to the 1/4' high-impedance input. If you're using a high-level source, use the -20dB pad to avoid distortion. You can use the Merge switch to connect stereo sources and sum them to a mono output. Connect the balanced XLR output to your audio system. Make sure to turn on the 48v phantom power for the box to work. When it comes to maintenance, keep the box clean and dry. Avoid exposing it to extreme temperatures or moisture. Check the connections regularly to ensure they're secure. If you encounter any issues, check the power source and connections first.
