dbx 520

The dbx 520 is your go-to solution for reigning in excessive sibilance in vocals and high-frequency dense material. Drawing from the esteemed dbx 902, this unit offers precise de-essing regardless of signal level variations. Its modular 500 Series design allows for thorough examination of signal differences, enabling de-essing even with level changes of up to 60dB.

Key features include a Frequency Control ranging from 800Hz to 8kHz, Gain Reduction Metering with expanded LED scale, and a De-essing Amount Range of 0dB to 20dB. Whether it’s vocals, drums, percussive instruments, or tricky material/reverb combinations, the dbx 520 has you covered.
