[. . . ] FBQ2496 Users manual Version 1. 0 March 2005 FEEDBACK DESTROYER PRO FEEDBACK DESTROYER PRO FBQ2496 IMPORTANT SAFETY INSTRUCTIONS DETAILED SAFETY INSTRUCTIONS: 1) Read these instructions. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. 8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] The level meters are adapted automatically to the selected nominal level, so that the FEEDBACK DESTROYER PRO will always work in its optimum operating range. OUTPUT LEFT/RIGHT Both of the FBQ2496 outputs are also laid out as balanced 1/4" TRS and XLR connectors. 1. Briefly press the LEARN button. (S 0 = no Single-Shot filter selected, S20 = all filters deployed as Single-Shot filters). The FBQ2496 immediately starts searching for critical frequencies at maximum speed and deploys as many SingleShot filters as necessary (for this to work, your room has to have a functioning PA system with a signal fed into it). The number of filters deployed will be increased on a per-need basis and will be shown in the display. You can use the wheel to change the number of Single-Shot filters afterwards as well. FBQ2496 FILTERS The FBQ2496 filters can be set up in an extremely narrow-band fashion. This way, the FBQ2496 changes the way your music sounds to such a minor extent that the actual change is absolutely negligible and inaudible. AUTOLEARN mode This function is useful for automatically setting up Single-Shot filters before the start of a live performance (priming the unit). Then, the following happens automatically: s s s The button LED blinks. A time countdown runs in the display, from 16 seconds to zero (L16, L15, . . . , L 1, L 0). The FBQ2496 creates impulses with a signal level of -15 dB in order to provoke feedback. The overall amplification of your FBQ2496 is incrementally increased from 0 dB to 15 dB). The FEEDBACK DESTROYER PRO detects the critical frequencies and lowers them in an extremely narrow-band fashion. Select whether you wish to run your FBQ2496 in stereo or in mono ( ). Critical frequencies are consecutively lowered and stored in the storage slots of the Single-Shot filters. The LED on the LEARN button is no longer lit and the display shows run. The frequency of the adjusted Single-Shot filters can not be manually changed afterwards. However, minor feedback frequency changes are implemented automatically. Gain adjustment is also automatically performed in the background, constantly adjusting to the current conditions. If a satisfactory setting for the Single-Shot and automatic filters has been achieved, you can keep this setting by pressing the FREEZE button. The display shows: -. 3. + Let us assume that both FEEDBACK DESTROYER PRO channels are coupled in stereo. The 20 filters pro channel can be divided up among Single-Shot filters, automatic filters and parametric filters (fig. 4. 2). + + The number of all filter types per channel is always 20!
