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
