Important Safety Instructions 1. 2. 3. 4. 5. 6. 7. 8. 9. Please read all instructions before operating the unit. Keep these instructions for future reference. Please heed all safety warnings. Follow manufacturers instructions. Do not use this unit near water or moisture. Clean only with a damp cloth. Do not block any of the ventilation openings. Install in accordance with the manufacturers instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or third prong is provided for your safety. When the provided plug does not fit your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on and pinched, particularly at plugs, convenience receptacles and at the point at which they exit from the unit. Unplug this unit during lightning storms or when unused for long periods of time. Refer all servicing to qualified personnel. Servicing is required when the unit has been damaged in any way, such as power supply cord or plug damage, or if liquid has been spilled or objects have fallen into the unit, the unit has been exposed to rain or moisture, does not operate normally, or has been dropped. 10. 11. 12. 2 Table of Contents Introduction S gate 4 Features Controls and Functions Front Panel Layout Rear Panel Layout Operating the S gate 4 Setting Up the S gate 4 Gating A Signal Using The Filters Using The Ducker 2 3 4­5 4­5 6 7 8 9 Dynamics Processing 101 Applications System Set-ups S gate 4 Connections Block Diagrahm Specifications 10­11 12 13­14 15 16 17­18 Copyright 2001, Samson Technologies Corp.

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. The S gate 4 is a powerful tool for live sound and recording, enabling you to clean up your mix by eliminating hums, buzzes, noisy tracks and microphone bleed. S Gate 4s DFT (Dual Filter Trigger) enables pinpoint accuracy by letting you control the exact frequency that will open the gate. A full complement of envelope controls including Threshold, Attack, Release, Hold and Range facilitate a wide range of applications from a subtle clean up of a vocal track, to a drastic effect like gating reverb chambers. With proper care and adequate air circulation, your S gate 4 will operate trouble free for many years. We recommend you record your serial number in the space provided below for future reference. Serial number: Date of purchase: Should your unit ever require servicing, a Return Authorization number (RA) must be obtained before shipping your unit to Samson. Without this number, the unit will not be accepted. Please call Samson at 1-8003SAMSON (1-800-372-6766) for a Return Authorization number prior to shipping your unit. Please retain the original packing materials and if possible, return the unit in the original carton and packing materials. 2 S gate 4 Features CH 1 HIGH GAIN REDUCTION dB 30 24 18 12 6 4 2 1 LINK CH 2 HIGH GAIN REDUCTION dB 30 24 18 12 6 4 2 1 CH 3 HIGH GAIN REDUCTION dB 30 24 18 12 6 4 2 1 LINK CH 4 HIGH GAIN REDUCTION dB 30 24 18 12 6 4 2 1 POWER TRIGGER +4 20 ATTACK .25 HOLD 1 RELEASE 1 RANGE 40 IN/OUT TRIGGER +4 20 ATTACK .5 HOLD 1 RELEASE 1 RANGE 40 .1 TRIGGER +4 20 ATTACK .5 HOLD 1 RELEASE 1 RANGE 40 IN/OUT TRIGGER +4 20 ATTACK .5 HOLD 1 RELEASE 1 RANGE 40 4 CHANNEL GATE .1 KHz 10 .1 KHz 10 KHz 10 .1 KHz 10 -50 dBu +20 .3 mSec 300 .01 Sec 4 .02 Sec 5 1 dB 80 -50 dBu +20 .3 mSec 300 .01 Sec 4 .02 Sec 5 1 dB 80 -50 dBu +20 .3 mSec 300 .01 Sec 4 .02 Sec 5 1 dB 80 -50 dBu +20 .3 mSec 300 .01 Sec 4 .02 Sec 5 1 dB 80 30 LOW Hz 3K 30 KEY KEY LISTEN DUCKER IN/OUT LOW Hz 3K 30 KEY KEY LISTEN DUCKER LOW Hz 3K 30 KEY KEY LISTEN DUCKER IN/OUT LOW Hz 3K KEY KEY LISTEN DUCKER The Samson S gate 4 dynamics processor utilizes the latest technology in gain management design.
