Operations160S 160SL to your system Connection Introduction 160S 160SL Installation considerations Inspection 160S Furthermore, it is interesting to note that by comparing the input and output waveforms for the compressed mode, the quietest sections of the input signal have been effectively raised in level, whereas the loudest sections have been effectively decreased in level. The overall effect is that both ends of the dynamic range have been pushed toward the middle.
Operating Connection Installation 160SL 160S to your system 160SL 160S considerations Operations Introduction Inspection For best results the Limiter functions of your compressor should be used in conjunction with the Compressor functions. 160SL 160S When we at dbx decided to make a premium compressor that would perform to the industry’s highest standards, it became readily obvious that every component and design strategy had to be chosen with high-performance foremost in mind.

PeakStop is the process first introduced on the dbx 165A compressor/limiter, which is still very popular today. PeakStop is made up of an extremely fast-reacting detector, called Instantaneous Transient Clamp.
Operating Connection Installation 160SL 160S controls to your system 160S 160SL considerations notes Inspection Operating Operating By pass Switch and LED: This switch activates a hard-wire relay bypass system, which allows the audio signal to pass through the compressor directly from input to output, even when the 160SL is turned off.
Inspection 160S 160SL to your system Connection controls Operating 160S 160SL considerations Installation notes Note that the gain reduction scale is linear in dB as opposed to the standard VU markings on the upper 160S Operating scale on which input and output levels are monitored. This allows for easy visual indication of gain 160SL reduction, as it can be read in a fraction of a second, with only a fleeting glance from the engineer.

Operating 160S 160SL to your system Connection notes Operating 160S 160SL considerations Installation to your system OverEasy And Hard Knee Connection® 160S 160SL In a typical hard-knee compressor, the threshold control sets a reference level above which input signals will be attenuated in the manner defined by the setting of the Compression ratio control. Input signals which fall below this level will pass through unprocessed.

A stereo program is one where the two channels are recorded and/or mixed to create the illusion of a single unified panorama of sound.

Operating Connection Installation 160S 160SL to your system notes 160SL 160S to your system considerations Operating Operating Connection De-Essing To apply de-essing to vocals (i.e., a reduction of sibilance), use a parametric equalizer in the sidechain circuit and set it for high frequency boost in the specific frequency range where the vocal hiss or lisp occurs (generally in the 4-6kHz region). This pre-emphasizes the already hissy vocal input to the detector.
