Single Channel, Passive Direct Box 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. Features: Converts a high-impedance (1/4") input to a balanced, low-impedance (XLR) output High-quality transformer for low distortion and an isolated signal path Output signal can be sent via a long cable to a mixer or PA system without frequency loss Passive circuit does not require a power supply or batteries Specifications: Application: Acoustic guitars, bass guitars, keyboards, and more Construction: Metal Dimensions: (W)4.75" x (H)1.375" x (D)2.875" Input Impedence: 350K Ohms Inputs: 1/4" Output: XLR Output Impedence: 80 Ohms Pad: 20dB, 40dB, Ground Lift: Yes Power: Passive/not required Product Type: Direct Box Weight: 0.5 lb
