Our DB500 Passive 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 low-distortion passive circuitry that doesn't require power, a -20 dB or -40 dB pad switch to prevent clipping, a ground-lift switch to defeat ground-loop hum, and a throughput connector to pass unaltered signal to a stage amp. Its heavy-duty metal enclosure protects the internal components and ensures reliable performance.
