PEQ-5B PARAMETRIC EQUALIZER

With its advanced state-of-the-art features and versatile utility, the PEQ-5B five-band parametric equalizer is a rugged workhorse, designed for long-haul reliability in the studio and live sound reinforcement applications.

Full professional features include: 15dB boost/cut per band, constant-Q, state-variable filter circuitry for precision control of tone coloration, parallel phase filters for minimal phase shifting, and tunable high and low cut filters.
Each band is independently switchable and adjustable in bandwidth (.03 to 2 octaves wide), allowing a range of adjustment from tight notching to extreme boost/attenuation by band overlapping

Servo-balanced XLR and 1/4" TRS inputs and outputs
Bypass switches on each channel
12-segment LED switchable Input/Output meter
Housed in a single rackmount metal housing (1U)
