This warranty gives you specific legal rights, and you may also have other rights which vary form state to state. [. . . ] Therefore the cymbals may be removed from ` eligibility' by using a high cut filter to filter out the high frequencies of the cymbals. The gate will no longer open up during cymbal crashes, leaving the low frequencies of the tom-tom to properly open the gates. Essentially, all signals above the threshold setting are passed through unaffected, whereas signals below the threshold setting are reduced in level by the amount set by the ratio and/or range control. Ratio The expansion ratio sets the amount of noise reduction applied to a signal once the signal has dropped below the expansion threshold. For example, a 2:1 expansion ratio attenuates a signal 1dB for every 1dB it drops below the threshold. For example: If the Expander calls for 40dB of attenuation but the Range is set to 20 dB of attenuation, the signal will be attenuated by 20dB. Range The range is the amount of gain reduction that the processor closes down to. Therefore, if the range is set at 0dB, there will be no change in the signal as it crosses the threshold. If the range is set to -60dB, the signal will be attenuated (reduced) by 60dB, etc. A fast attack rate is crucial for percussive instruments, whereas signals such as vocals and bass guitar require a slower attack. Hold Hold time is used to keep the gate open for a fixed period of time following the signal going below the gate threshold. This can be really useful for effects such as `gated snare'where the gate remains open after the snare hit for the duration of the hold time then abruptly closes. Hold is only available when the ratio knob is set to GATE. Release The gate release time determines the rate at which the gate closes. Release times should typically be set so that the natural decay of the instrument or vocal being gated is not affected. Shorter release times help to clean up the noise in a signal but my cause ` chattering'in percussive instruments. Longer release times usually eliminate `chattering' and should be set by listening carefully for the most natural release of the signal. SC Mon The SideChain Monitor allows you to hear the frequency range that the Lo and Hi Filter are operating on. Link Using the Link function, you can link together two channels of the GTX44 for stereo operation. When linked, the processors follow the setting of linked channel to the left, which becomes the master. Duck Ducking lowers the level of the audio signal based upon the level of the sidechain audio signal. If the unit is in gate mode, then you can DUCK according to what the range setting. A typical application is paging: A ducker senses the presence of audio from a paging microphone and triggers a reduction in the output level of the main audio signal for the duration of the page signal. [. . . ] 1U Rack TROUBLESHOOTING Ghost Meters The inputs of the CL44 are not designed to be overdriven. In the event that you do overdrive the inputs on one or two channels, the meters of the other two channels (if not in use) may show activity. This "ghost activity" is not signal bleed, it is sidechain crosstalk. It will not change or affect the processing power or ability of your unit. [. . . ]
