The dbx 530 Parametric EQ offers unique degree of equalization flexibility in the popular 500 Series format. Based upon the classic dbx 905, the dbx 530 is an uncompromising equalizer offering true, fully parametric operation of all three filter bands dbx has much-heralded history with modular processors dating back to our 900 Series, and the dbx 530 continues that tradition. The dbx 530 feet overlapping bands each offer control of frequency bandwidth and up to 15dB of reciprocal cut or boost to provide exact, complimentary filter action for the most demanding of equalization needs. For problem situations requiring the removal of spurious signals, each of the bands can be independently switched into infinite notch mode without affecting the operation of others. In situations where shelving equalizer will produce better results than peaking one, the 530s high and low bands can be independently switched from peaking to shelving operation. You can also make instant affectedbypassed comparisons using the 530 feet On switch. Load up your 500 Series rack with dbx 530 Parametric EQs and cut your way through mixes like an audio surgeon
