Anleitung Zusammenfassung


The factory default is 1kHz, but each filter is adjustable from 20Hz to 20kHz in 1Hz steps. Carefully sweeping a narrow bandwidth filter through a problem feedback area, with just a slight boost, is a quick way to find the exact frequency causing feedback trouble. Once the offensive frequency has been found, cut the filter’s level, and then adjust the bandwidth as narrow as possible while still eliminating the feedback problem. Bandwidth is adjustable from about 1/64 octave to four octaves, and the lower the bandwidth (higher Q), the less audible the filter action will be. Finding the problem frequency is relatively easy, but finding the best combination of cut and bandwidth takes a little practice. Again, it is well worth the time getting comfortable with the notching procedure, so that problems can be quickly addressed with a sufficient but minimal amount of corrective EQ. All Pass filters: All pass filters have no effect on frequency amplitude, but rather are used to adjust the phase response of the signal at a given frequency, and are often used in conjunction with a frequency-domain filter to correct phase changes. At low frequencies, there is 0 degree phase shift, at the All Pass filter center frequency there is -180 degrees of phase shift, and at high frequencies there is -360 degrees of phase shift. Each input channel has an EQ On/Off button for all filters, and in turn each filter band has its own bypass button. The Flatten Curve function returns all filters to 0dB, but preserves the frequency and bandwidth of any used filters. 8.1i Noise Gate Noise gates are used to minimize unwanted or ambient low level signal from an individual mic input. THRESHOLD is the level above which an input signal will pass through, and below which its signal is turned off. RANGE is the amount of attenuation in dB which the noise gate attenuates the signal when the gate is off. ATTACK and RELEASE control the time characteristics of the gating action. Attack sets the amount of time it takes for the gate to open or gated signal to turn on. Release sets the time required for the gate to close back up when the input signal falls below threshold. 8.1j Autoleveler An Autoleveler is a dynamics processor used to automatically boost or cut a signal to a user defined target level. TARGET LEVEL is the primary setting in an autoleveler, as it determines the desired constant level to which an input is boost or cut. Both basic mode and advanced mode utilize the target level control, but basic mode simplifies setup. In BASIC MODE, target level, action, and maximum gain are the available controls. ACTION is selectable to gentle, normal, or aggressive, and automatically adjusts the following controls found in advanced mode: Action Ratio Hold Time Gain Incr. Rate Gain Dec. Rate Aggressive 10:1 0 Sec 20ms/dB 5 ms/dB Normal 4:1 1 Sec 50ms/dB 10 ms/dB Gentle 2:1 2 Sec 100ms/dB 20 ms/dB MAXIMUM GAIN controls the threshold below target using the following formula: Thr = Max Gain / (1/Ratio - 1) In ADVANCED MODE, THRESHOLD BELOW TARGET determines the input signal level relative to the target level, above which the autoleveler increases gain, and below which no action is taken. RATIO is defined as the relationship of input level change in dB to output level change in dB. It is a measure of how aggressively the autoleveler changes the gain to maintain a constant output target level. GAIN INCREASE RATE and GAIN DECREASE RATE are Operating Manual - ne24.24M Matrix Processor used to prevent sudden, choppy sounding level changes to an input signal having a wide dynamic range. HOLD TIME is used in conjunction with gain change rate, and is defined as the time after the input signal falls below the threshold during which the autoleveler’s gain is held constant before it returns to unity gain. The purpose is to reduce the amount of gain “chatter” and abrupt signal cutoff when the input signal is hovering around the threshold level. Advanced settings which are different than the three Basic action settings results in a USER DEFINED display in the basic action control. 8.1k Ducker A Ducker is used to attenuate the level of selected input channels when one or more “Trigger” inputs have signal present. Input channels can be set to one of four ducker modes: 1.) BYPASS - no ducking action applies. 2.) DUCKED PROGRAM - signal present on other “Trigger” selected input channels act to attenuate this input channel. 3.) LOW PRIORITY TRIGGER - signal present on this input channel attenuates all other inputs set to “Ducked Program”. 4.) HIGH PRIORITY TRIGGER - signal present on this input channel fully attenuates all other inputs set to “Ducked Program”, as well as all other channels set to “Low Priority Trigger”. 5.) FILIBUSTER - signal present on this channel fully attenuates all other channels until the signal drops below its threshold to allow other channels to come on. TRIGGER THRESHOLD determines the signal level on a trigger input at which point the ducked pro...
