On-Stage's DB1100 Active DI Box converts any high-impedance 1/4" source to a low-impedance XLR signal ready to send via a long cable run to a mixer or PA system. Features include a merge option that enables two discrete inputs to be output as a summed-mono signal, a throughput connector to pass unaltered signal to a stage amp, a -15dB pad switch to prevent clipping, low-cut switch to reduce rumble, polarity switch for blending with a mic signal or interfacing with nonstandard equipment and a ground-lift switch to defeat ground-loop hum. Its heavy-duty metal enclosure protects the internal components and ensures reliable performance.
