Whirlwind IMPAD40 -40dB Inline Attenuation Pad

The Whirlwind IMPAD40 is a passive inline attenuator that reduces audio signal levels by a fixed 40dB. Built into a compact XLR barrel connector, it slots seamlessly into any balanced signal chain where a source output vastly exceeds the acceptable input level of the receiving device. This makes it particularly valuable in scenarios such as feeding a line-level output into a sensitive microphone preamp, interfacing broadcast-level equipment with consumer-grade gear, or troubleshooting persistent clipping issues in complex signal chains.

True to Whirlwind's reputation for road-ready construction, the IMPAD40 features a durable metal housing and reliable XLR connectors that withstand the rigors of live sound and studio use alike. Because the attenuation is achieved through a precision resistive network rather than active circuitry, it requires no power and introduces no noise, distortion, or tonal changes. For audio engineers who need a quick, dependable way to knock down an excessively hot signal, the IMPAD40 is a set-it-and-forget-it solution.
