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. 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 4ʼs 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 rec-
ommend you record your serial number in the space provided below for future reference.
