65LFLim Hold (Low Frequency Limiter Hold Threshold)During operation of the limiter, the algorithm is watching for very small decreases in audio level,such as what occurs right after a sudden peak. When this occurs, the limiter release is temporarilystopped. The result is a drastic reduction in intermodulation distortion and a more open sound,even though the audio is still quite dense. The level at which the hold takes place is controlled bythe setting of the hold Thresh control. Higher numbers cause the hold to activate at higher audiolevels. The action of limiter hold also works in conjunction with the preceding AGC gates toreduce noise rush up during periods of no audio or pauses in speech.Lim Thresh (Limiter Threshold)This control adjusts the threshold level of where limiting begins. Lower settings will increase theamount of limiting and decrease the level going to the following Bass Clipper (low band only) orFinal Limiter stage. Conversely, higher settings will raise the limit threshold, causing less limitingbut feeding more level into the following Bass Clipper (low band only) or Final Limiter stage.Normally, we recommend leaving the Limiter Thresholds at the factory setting.<-ExitClick on this option to return to the Adjust Processing submenuMid Band LimiterSee description of settings for Low Band LimiterPresence Band LimiterSee description of settings for Low Band LimiterHigh Band LimiterSee description of settings for Low Band LimiterBass ClipperThe Bass Clipper operates between the output of the Low Band Limiter and the Low Band Mixer, the output ofwhich feeds the Final Limiter. Its purpose is to keep excessive bass out of the Final Limiter, reducing IM(intermodulation) distortion while keeping and even enhancing the bass punch of the program material. There aretwo different Bass Clipper styles available (described below).NOTE: Defeating both of the bass clipper sections will not reduce delay throughput.Clip Drv (Bass Clipper Drive)Adjusts the drive level to the Bass Clipper over a range of +/- 6 dB. Higher settings will increasethe amount of Bass Clipping, increasing bass density while keeping the actual peak bass level fedto the Mixer the same This allows you to reduce the Low Band Mixer control to reduce IMdistortion in the Final Limiter without reducing the amount of perceived bass in the programmaterial. Be careful! Too much clipping by the Bass Clipper can soften bass 'punch'. It may alsobe heard as a “rattling” sound in the bass or cause additional artifacts in the codec following theOmnia ONE Studio Pro. |
