Mackie MDB-2P Stereo Passive Direct Box

Stereo Passive Direct Box The Mackie MDB-2P is a stereo passive direct box designed to connect two mono instruments or a single stereo instrument to microphone preamps for musicians and audio engineers in recording sessions, houses of worship, and live stage applications. It converts high-impedance, instrument-level signal via its 1/4" TS unbalanced inputs to low-impedance, mic-level outputs via balanced XLR 3-pin jacks. Two 1/4" TS thru jacks allow simultaneous connection to amplifiers or pedalboards. Each channel offers a -15 dB pad for reducing the input level to prevent distortion when using a high-gain source. The ground-lift switch inhibits hum caused by ground loops. Due to passive design principles, the MDB-2P requires no batteries or power supply. Its sturdy steel chassis enables confident use in the studio or on the road.Features: Connect two mono instruments such as guitars or basses or a stereo instrument such as a keyboard to microphone preamps Converts high-impedance, unbalanced 1/4" TS inputs to low-impedance, balanced XLR mic-level outputs 1/4" thru jacks for routing to amplifiers or pedalboards Per-channel -15 dB pad prevents overloading when accepting signal from a loud source Ground-lift switch minimizes hum Passive design requires no batteries or power supply Specifications: Type: Passive Input Connections: 2 x 1/4" TS unbalanced Output Connectors: 2 x 1/4" TS unbalanced 2 x XLR 3-pin balanced Input Impedance: 140 kOhms unbalanced Output Impedance: 400 Ohms unbalanced Impedance Ratio: 350:1 Pad: -15 dB Controls: 2 x pad switches 1 x ground-lift switch Frequency Response: 20 Hz to 20 kHz (±0.2 dB) Dynamic Range: 128 dB Total Harmonic Distortion: 0.002% from 1 kHz Power Requirement: None Construction Material: Heavy-gauge steel chassis Dimensions (H x W x D): 1.5 x 3.4 x 5.8" / 38 x 86 x 147 mm Weight: 0.8 lb / 0.4 kg
