Product Overview

Any engineer knows that excessive sibilance in vocals and high frequency-dense instruments makes for a harsh tone and begs for feedback concerns. The 520 uses dbx's legacy technology to help you expertly tame the noise. Based upon the legendary dbx 902, the dbx 520's unique features make it possible to achieve an exact amount of de-essing regardless of variations in signal levels.

The dbx 520 examines the differences in dB between the high frequency and full-bandwidth portions of a signal, allowing de-essing of signals which change in level by as much as 60 dB. The Frequency Control features a range from 800 Hz to 8 kHz, and the De-essing Amount Range operates from 0 dB to 20 dB, all in its compact 500 Series design. And the Gain Reduction Metering LEDs let you see at a glance how your 520 is operating.
