Our DB2050 Active Multimedia DI Box converts any line-level stereo source to a low-impedance discrete stereo XLR signal ready to send via a long cable run to a mixer or PA system. Features include a throughput connector to pass unaltered signal to a stage amp, a -15 dB pad switch to prevent clipping, and a ground-lift switch to defeat ground-loop hum. A variety of input connectors enable convenient use with various sources. Its heavy-duty metal enclosure protects the internal components and ensures reliable performance.
