This used DBX 902 900-Series De-Esser Module will ship in an anti-static bag.
The dbx model 902 De-Esser is designed for use in the F900A mainframe or the FS900 miniframe. The 902's unique features make it possible to achieve the exact amount of de-essing desired regardless of variations in signal levels.
The Model 902 De-esser can be used as a conventional broadband de-esser, or for attenuating only a user-determined portion of the high frequency range of the audio signal. Gain reduction is adjustable from 0 to -20 dB. A feature unique to the 902 is its continuous analysis of the input signal spectrum, thereby providing the exact amount of de-essing selected regardless of the signal level. The 902 does not require re-calibration for signal level changes, just set it and forget it.
