อีควอไลเซอร์ dbx รุ่น 2231 (มหาจักร) EQUALIZER

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
