2 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.

6 Operating The S gate 4 Whether you are an experienced audio engineer , just starting out, or you just want to experiment, follow the steps below to get going.
7 Operating The S gate 4 GA TING 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.
8 Operating The S gate 4 USING THE FIL TERS The S gate 4 employs a DFT (Dual Filter T rigger) 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.
9 USING THE DUCKER S gate 4ʼs Ducker feature is a powerful tool for automatically mixing dif ferent sound sources. Y ou 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.
10 Dynamics Processing 101 T o 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.
1 1 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.
12 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 of f.
