Mackie MDB-1A Active Direct Box

The Mackie MDB-1A Active Direct Box delivers increased headroom and ensures a distortion-free operation. It is ideal for instruments like basses and guitars that have active pickups and preamps. It helps convert a high-impedance, instrument-level signal to a low-impedance, microphone-level output. The integrated ground-lift switch minimises hum.

FAQs:

How many I/O ports are available?

The active direct box features 2 line inputs (with Merge ON), 1 XLR input, and 1 Thru output (with Merge OFF) for conversion of a high-impedance instrument-level signal to a low-impedance, microphone-level signal.

What are the switches used for?

The Merge switch allows the connection of stereo sources that can be summed to mono at the output, used for stereo sources like media players and keyboards. The ground-lift switch inhibits hum caused by ground loops.

Does it have an input pad?

It features a -20 dB input pad that helps prevent overloading and reduces the input level when accepting a signal from a high-gain source to ensure a distortion-free performance.
