MACKIE MDB-1A ACTIVE DIRECT BOX
From acoustic guitars to laptops, always sound your best with MDB Series Direct Boxes. The Mackie MDB Series will give you the peace of mind that your sound will faithfully get to your audience the way that you hear it on stage.
The Mackie MDB-1A is an active direct box designed to connect a single instrument, such as a guitar, bass, or keyboard to a microphone preamp for musicians and audio engineers in recording sessions, houses of worship, and live stage applications. It converts a high-impedance, instrument-level signal via its 1/4" TS unbalanced input to a low-impedance, mic-level output via its balanced XLR 3-pin jack. A 1/4" thru jack allows simultaneous connection to an amplifier or pedalboard. A -20 dB pad reduces the input level to prevent distortion when using a high-gain source, and the ground-lift switch inhibits hum caused by ground loops. Additionally, there are switches for polarity and a 120 Hz high-pass filter. The Merge function allows the Thru jack to be used as a second, simultaneous input. Due to its active design, the MDB-1A operates on phantom power. A sturdy steel chassis enables confident use in the studio or on the road.
