DBX 2231 Graphic Equalizer/Limiter with Type III™

• Revolutionary instant encode/decode Type III® Noise Reduction in-circuit at the push of a button. Increases S/N ratio by up to 20dB
• Patent-pending PeakPlus™ Limiter threshold range from 0dBu to +24dBu (off) can transparently tame the wildest hits or the subtlest nuances of any signal
• Four segment LED bargraph for BOTH Gain Reduction AND Output Level
• Status LEDs offer visual feedback for all settings on the front panel
