The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. [. . . ] You can use the TRIGGER, ATTACK, HOLD and RELEASE to fine-tune and dial in just the sound of the kick drum. Note: You can hear the effect of the DFT circuit on the trigger or side-chain input by pressing the KEY LISTEN switch. When engaged, the KEY LISTEN circuit routes the trigger signal to the audio output allowing you to hear what effect the filters have on the side-chain. The example below shows a typical set up for using DFT while gating drum microphones. Kick Drum with the filter set on 30Hz and 200Hz. Snare Drum with the filter set on 1KHz and 2KHz.

You can use the S gate 4s 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. This is a great way to mix a sax or guitar solo around a vocal improvisation. You can experiment with the ducker by using a vocal track or microphone and stereo sound source, such as a CD player. · Connect the first two channels of the S gate 4 to the main left and right insert points of your mixer. Now take an output from your mic or vocal channel, either from a direct, auxiliary or bus output and connect to the channel one KEY input on the S gate 4s rear panel. Set both channels controls to the default positions as described in the section "Setting Up the S gate 4". Set the RANGE control on both channels to 40. · · · CH 1 HIGH GAIN REDUCTION dB 30 27 24 18 12 6 2 1 LINK CH 2 HIGH GAIN REDUCTION dB 30 27 24 18 12 6 2 1 CH 3 HIGH TRIGGER +4 20 ATTACK . 25 HOLD 1 RELEASE 1 RANGE 40 IN/OUT TRIGGER +4 20 ATTACK . 25 HOLD 1 RELEASE 1 RANGE 40 . 1 TRIG NNEL DER TE . 1 KHz 10 . 1 KHz 10 KHz 10 -50 dBu +20 . 3 mSec 300 . 07 Sec 4 . 02 Sec 5 0 dB 100 -50 dBu +20 . 3 mSec 300 . 01 Sec 4 . 02 Sec 5 0 dB 100 -50 d 30 LOW Hz 3K 30 KEY KEY LISTEN DUCKER IN/OUT LOW Hz 3K 30 KEY KEY LISTEN DUCKER LOW Hz 3K · · · Press the DUCKER and KEY switches to the IN position. Press the channel one and two IN/OUT switch to the IN position and engage the LINK switch. Play some music from a sound source (such as a CD player) into two channels of your mixer. Now when the vocal track or mic is playing, youll hear the music track drop by 40 dB. You can experiment with different RANGE settings until you find the balance you like. 9 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 output. 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. All of these processes have a unique effect on a signal, but one common element they share is that in one way or another they control gain. Some dynamics processors control gain in a subtle way by slightly reducing how soft and loud a signal is, while others make drastic changes in gain like reducing the signal until its off. Applications for dynamics processing can be categorized by two distinct groups; first, to treat a signal that has an unpredictable dynamic range and make it predictable, and second, to create a "sound" by squeezing out the dynamic range. Whether used for a live sound application, recording, mixing or mastering, dynamic processors like the S gate 4 are valuable tools for controlling gain. The following is a basic overview of dynamics processing and how it is used to improve the quality of recorded and live sound. COMPRESSOR A good compressor is one of the most useful tools in live sound and recording. [. . . ] On a single instrument, like a rhythm guitar track, you can clean up the performance by gating the track. To do this, set a release time to exactly match the tempo of the music, so that you hear the guitar playing, but stopping (gate closed) just before the beat. By doing this, a less than perfect rhythm track can quickly sound like it was played by a great session guitarist. Also, pay attention to the space that the S gate 4 creates in the track, since very often a great performance really jumps out when it is framed by the space, or silence around the track. [. . . ]
