The dbx Models 163 and 164 are compressor/limiters featuring the proprietary Over Easy compression characteristic, which provides virtually inaudible gain control at ratios up to infinite compression. The Model 163 is a mono unit, while the Model 164 is a stereo-tracking version that works with a pair of channels. Both units utilize true-rms-level detection and feedforward gain reduction to ensure natural-sounding performance and stability.
