User manual PEAVEY FEEDBACK FERRET D

[. . . ] Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: To reduce the risk of electric shock, do not remove cover. WARNING: To prevent electrical shock or fire hazard, this apparatus should not be exposed to rain or moisture, and objects filled with liquids, such as vases, should not be placed on this apparatus. Before using this apparatus, read the operating guide for further warnings. [. . . ] The CLIP LED lights when the signal is 1/2 dB down from clipping. Bypass To bypass the Feedback Ferret D, press and hold the reset button until the LED stops blinking and has constant illumination. Feedback could occur again ---- Very Loudly!Filters 9­16 (dynamic) will clear first, as indicated by their non-lit LEDs. Releasing the button at this point will leave the static filters (1­8) in their current state. (Note: Feedback often occurs around a range of pitches or frequencies, not necessarily at a single pitch. By engaging this button, the Feedback Ferret D widens the effective range of each filter and subsequently uses fewer filters to accomplish the same result. ) Panic Mode (Quick Filter) Panic filters are a special class of filters designed to quickly control sudden, extreme feedback. Setup/Preset This switch toggles the next bank of buttons between SETUP mode and PRESET mode. preset Mode (LED on) The four buttons labeled 1-4 are used to store and recall Feedback Ferret D settings. To store, press and hold the desired preset button until the LED stops blinking. to recall a stored preset , press the corresponding preset button. Note: using the power up recall switch on the rear panel, the Feedback Ferret D can be set to recall preset 1 automatically each time the power is turned on. Setup Mode (LED off ) In this mode the four function buttons each take on a separate function as indicated on the front panel. Normal/Filter Learn FILTER LEARN mode is used to preempt feedback by setting fixed filters before the performance starts. Pressing the button will turn the LED on to indicate you are no longer in NORMAL operation mode. To take advantage of this mode, see "Operating Instructions" later in the manual. In stereo mode, the Feedback Ferret D reacts to feedback in both the left and right channels by configuring stereo filters. In dual mono mode, each channel of the Feedback Ferret D acts independently to seek out and eliminate feedback. In dual mono mode the left and right channel selector buttons are used to switch the display and function buttons between channels. Mono View Left and Mono View Right These buttons are used to switch the front panel buttons and display between channels in the dual mono mode. the LED for the selected channel will be lit. [. . . ] If feedback continues, the filter depth is progressively increased until the feedback is gone. If the feedback is momentary, such as a short squeal, the Feedback Ferret D applies a filter but slowly releases it in . 10 dB steps until it is returned to flat (0 dB). if the same frequency causes feedback again , the same filter will be reapplied.
