Passive DI gives you level control to tame hot signals from high output instruments.

The SPDI passive direct box from Live Wire Solutions is a high-quality, passive DI box designed for interfacing instruments like electric guitars, basses and keyboards with PA systems, mixing consoles and recording equipment. With variable attenuation, you can adjust the input signal to match your instrument's output, ensuring the best signal for any application. When the ground lift switch is engaged, it severs the ground connection between the input and XLR output, eliminating unwanted noise. With the ground switch disengaged, the ground connection remains intact.

Versatile Attenuation Provides Maximum Flexibility

The SPDI passive direct box allows you to attenuate your instrument's signal from 0 to 40dB using a multi-step pad, providing the optimal level for any equipment. This allows you to match the DI box to instruments with a wide range of output levels for the best signal in any situation. The stepped attenuation pad includes 0dB, -20dB and -40dB settings, giving you a high degree of control over your instrument's signal level.

Ground Lift Switch Eliminates Unwanted Noise

A ground lift switch allows you to sever the ground connection between the input and balanced XLR output, which can help eliminate unwanted hum and buzz. When the ground lift switch is engaged, it lifts the ground on the XLR output, breaking the connection between the input ground and output ground. This is useful when there are ground loops between equipment. With the ground lift switch disengaged, the ground connection remains intact between the input and output.

Rugged, Durable Construction

The SPDI passive direct box is built to withstand the rigors of live performance and touring. Its rugged, durable enclosure is designed to protect the internal components from physical damage. The box also features high-quality, studio-grade XLR and 1/4" connectors for maximum signal integrity and years of reliable use. Overall, the SPDI Passive Direct Box is a high-performance, rugged solution for interfacing your instrument with pro audio equipment.
