dbx 2231 Graphic EQ/Limiter

0.00

The dbx 2231 Graphic Equalizers is a useful audio signal processing tool for situations where precise frequency control is required across the audible frequency spectrum. The 2231 can tune any acoustical environment from the studio to the concert hall to decrease resonances, increase clarity, and flatten the overall frequency response of the environment. The long throw faders of the EQ allow very precise settings for accurate equalization curves.

All active equalizers, by nature of design, add noise when boosting or cutting that can easily degrade the otherwise acceptable signal-to-noise ratio of a sound system. Drastic equalization can result in a loss of 20dB or more signal to noise. dbx Type III Noise Reduction was engineered specifically for applications such as this. It provides up to 20dB of noise reduction, thus restoring the dynamic range necessary for even the most demanding professional sound systems. The combination of proper wiring, proper gain structure and TYPE III™ Noise Reduction should render your sound system virtually noise free.
