Adjustable In-Line Attenuator


The Vu VU-ATTEN is an adjustable in-line attenuator that enables balanced low-impedance microphones to connect to low- to mid-impedance inputs in high-SPL applications. Adjusts via a -10dB, -20dB or -30dB switch to match the microphone output to the inputs of mixers, portable recording devices, and more. The VU-ATTEN prevents input overloading due to high-level signals and is compatible with phantom power.

  • Provides -10dB, -20dB, or -30dB attenuation to prevent overload of sensitive input stages
