Set of 2 pcs. Di BOX MDB-2P Mackie MDB-2P is a high-quality passive stereo direct box designed to convert unbalanced, high-impedance signals from instruments like keyboards and synthesizers into balanced, low-impedance signals suitable for professional audio mixers and recording equipment. This ensures a clean, noise-free signal over long cable runs, making it an essential tool for electronic musicians, live sound engineers, and recording studios. High-impedance 1/4" Inputs with Thru Outputs: Connect your instruments directly and send a parallel signal to an amplifier or monitor. Balanced XLR Outputs with Ground Lift: Provides a clean, balanced signal for long cable runs to a mixer, with a ground lift switch to eliminate hum and buzz. Ultra-low Noise and Distortion: Ensures pristine audio quality without unwanted artifacts. -15dB Pads: Attenuates hot signals from high-output sources, preventing distortion. Built-like-a-Tank Construction: Durable design to withstand the rigors of live performance and studio use. Front panel INPUT (1/4" TS): Connect your instrument (e.g., keyboard, synthesizer) here. THRU (1/4" TS): Provides a direct, unprocessed signal from the INPUT to send to an amplifier or stage monitor. PAD (-15dB): Engages a -15dB attenuation pad for high-output sources to prevent input clipping and distortion. Rear panel OUTPUT (XLR Male): Balanced, low-impedance output to connect to a mixer's microphone input. GROUND LIFT: Disconnects the ground connection between the input and output to eliminate hum and buzz caused by ground loops. On this auction I am selling 2 pcs. of MDB - 2 P.
