If you are not familiar with the operation of Gates, Duckers and Expanders, see the Operation section on page Manual-4 for a good tutorial. For those of you familiar with their operation, this quick start should help you get up and going fast. Basic Gating: The G4 allows complete Gate envelope control: Threshold, Attack, Release and Hold. [. . . ] Side-chain source switches remain independent in Link mode. Side-Chain: Normal / Listen The NORMAL / LISTEN switch allows the user to listen to the filtered side-chain key signal. When set to LISTEN, the filtered side-chain key signal is routed to the output. Listening to the filtered key signal assists in adjusting the side-chain filter. When set to NORMAL , the main processed audio signal is routed to the output jack. Side-chain Listen switches remain independent in Link mode.

In Duck mode, the HOLD time determines how long the signal remains ducked when the key input drops below threshold. The HOLD time is reasserted whenever the peak signal moves above the Gate or Duck threshold. The HOLD control has no effect in Expand mode. Depth / Ratio 60 80 dB LOW-CUT HIGH-CUT 40 20 0 2 1 4 6 8 n:1 DEPTH RATIO In Gate mode, the DEPTH control determines how many dB the signal is attenuated when the key input is at or below threshold. The RATIO control has no effect in Gate mode. In Duck mode, the DEPTH control determines how many dB the signal is attenuated (ducked) when the key input is at or above threshold. The RATIO control has no effect in Duck mode. In Expand mode, the RATIO control indicates the ratio of output change to input change when the key signal is at or below threshold. For example, with a ratio of 4:1, the output level decreases 4 dB for every 1 dB the key signal moves below threshold. The DEPTH control has no effect in Expand mode. The side-chain, 12 dB/octave Butterworth LOW-CUT and HIGH-CUT filters are used to limit the detector's response to a particular range of frequencies, thereby minimizing false triggering. These filters are only applied to the side-chain. They do not affect the main output (unless you accidentally leave the LISTEN switch engaged). Side-chain filtering is advantageous in virtually all dynamics control applications. For example: · Adjust the HIGH-CUT filter to tune out the mic bleed from the snare drum or cymbals when gating a kick drum or tom mic. Similarly, adjust the LOW-CUT filter to tune out the kick drum when gating a snare mic. [. . . ] Ducking is useful for voiceover and instrument solo applications. Example uses · Automatically duck music when an announcement is made. Connect the music signal to the main input, connect a signal from the announcement microphone to the side-chain key input. When the announcer speaks, the key input exceeds the set threshold, and music is automatically turned down. [. . . ]
