Our DB1050 Passive Multimedia DI Box converts any line-level stereo source to a low-impedance XLR mono signal ready to send via a long cable run to a mixer or PA system. Features include low-distortion passive circuitry that doesn't require power, a -15 dB pad switch to prevent clipping, a ground-lift switch to defeat ground-loop hum, throughput connectors to pass unaltered signal to a stage amp, a Hi-Z/XLR input selector, and a variety of input connectors to enable convenient use with various sources. Its heavy-duty metal enclosure protects the internal components and ensures reliable performance.
