  • Page 8: Using The Enhancer

    Operating The S•com plus USING THE ENHANCER The S•com plus’ ENHANCER switch can be engaged to activate the EFR (Enhanced Frequency Recovery) cir- cuit. By engaging the ENHANCER, the S•com plus EFR restores the high frequency content that can be lost when high gain reduction is applied.

  • Page 9: Dynamics Processing 101

    Dynamics Processing 101 To begin to understand dynamics processing, we must first understand what dynamics are. Dynamics, or the dynamic range of a signal or audio device, is the amount of level between the softest and loudest possible out- put. Dynamics processing is applied to a signal to manage the changes in level. Various types of processing units are available to control dynamics including Noise Gates, Expanders, Compressors, Limiters and De-Essers.
  • Page 10 Dynamics Processing 101 - Continued Soft-Knee / Hard-Knee In order to prevent harsh, unnatural envelopes on compressed signals sophisticated dynamics processors like the S•com plus feature an SKD (Smart Knee Detector) or automatic knee circuit. The Smart Knee Detector auto- matically switches from Soft-Knee when the signal is less than 10 dB over Threshold, to Hard-Knee when the sig- nal is 10db above Threshold.
  • Page 11 Applications Using the Expander/Gate to Remove Hiss and Noise The S•com plus is an extremely useful tool in reducing the level of unwanted noises. By using the Expander/Gate you can effectively fade the noise into the noise floor or abruptly turn the unwanted signal completely off. Let’s say you want to reduce the bleed or cross talk that occurs when different instruments are recorded in close proximity to each other.
  • Page 12 Applications Leveling a Vocal Track When recording a vocal track, the vocalist may change the distance between them and the microphone, or they may naturally have a lot of dynamic range in their performance. In either case, the sound engineer must decide how much compression should be used to balance the natural performance and printing a good level to tape or disk.
