- Page 4 Introduction Congratulations on your purchase of the Samson S Gate 4! The S Gate 4 is a four channel Expander/Noise Gate with frequency sensitive triggering, offering unparalleled control and sonic transparency impressing the most critical listeners. Never before have so many features been packed into a single rack space unit with four noise gates - period.
- Page 5 KEY LISTEN DUCKER IN/OUT The Samson S gate 4 dynamics processor utilizes the latest technology in gain management design. Here are some of its main features: • Full featured, four channel Noise Gate with Expander and Ducker on each channel in a sin- glespace, 19"...

Further sections in this manual will cover basic dynamics and the associated parameters, sys- tem set-ups and applications for using dynamics processing in recording and live sound applications.

Page 9: Gating A Signal
GATING A SIGNAL Unwanted noises, buzzes and hisses can be easily removed by using S gate 4. The idea is to have the Gate open only when the sound you want to hear is playing and to mute off and eliminate (Gate closed) the unwanted noises, buzzes and hisses. -
Page 10: Using The Filters
Operating The S gate 4 USING THE FILTERS The S gate 4 employs a DFT (Dual Filter Trigger) circuit which allows you to create an equalization contour on the trigger filter. The DTF is a two-stage, band-pass equalizer on the trigger or side-chain input. The filters are applied to the trigger whether it is derived from the audio input, or by the KEY input. -
Page 11: Using The Ducker
USING THE DUCKER S gate 4ʼs Ducker feature is a powerful tool for automatically mixing different sound sources. You can use the S gate 4ʼs Ducker when you want one signal to control the level of another channel or channels. One of the most popular examples of using a ducker is when you have a voice-over turn down a music program track. -
Page 12: 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 13 Dynamics Processing 101 - Continued Soft-Knee / Hard-Knee In order to prevent harsh, unnatural envelopes on compressed signals, sophisticated dynamics processors like the S gate 4 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 signal is 10db above Threshold.
- Page 14 Applications Using the Expander/Gate to Remove Hiss and Noise The S gate 4 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. Letʼs say you want to reduce the bleed or cross talk that occurs when different instruments are recorded in close proximity to each other.

CONNECTING THE S gate 4 The are several ways to interface the S gate 4 to support a variety of applications. The S gate 4 features servo- balanced inputs and outputs, so connecting balanced and unbalanced signals is possible without any signal loss. The S gate 4 can be used on a single instrument by connecting to a mixer channelʼs insert points, or on an entire mix "in-line"... - Page 18 Block Diagrahm...
