FEEDBACK DESTROYER PRO DSP1124P 6.4 Locked mode (“LO”) When the DSP1124P detects a feedback frequency in Single-Shot mode (see chapter 6.3), it automatically enters Locked mode, i.e. the filter locks to the trouble frequency and “keeps an eye” on it. To unlock such a filter, you need to switch it back to Single-Shot mode (see and chapter 7.2). 7. WORKING WITH PRESETS In order to store your favorite settings, the DSP1124P has ten user presets and one default preset. All operating parameters can be stored, so that your programs are recalled in full detail. Owing to state-of-the-art circuitry, no internal battery is needed, hence the memory contents will not get lost. In the default preset (DISPLAY: “--”), which serves as a starting point for your own programs, all filters remain in Parametric EQ mode, with bandwidth set to 1 octave, frequency to 500 Hz and 0 dB gain. 7.1 Recalling Presets The FEEDBACK DESTROYER PRO has ten presets, which can be overwritten. After power-up, the unit restores the last preset used. Use the JOG WHEEL to select another preset. The default preset is located before the first program. + Please note that the FEEDBACK DESTROYER PRO generally activates the newly selected presets only after about one second, which is indicated by a dot in the lower right corner of the DISPLAY. After loading the data, the FEEDBACK DESTROYER PRO enables the preset and the dot disappears. This brief interruption of the signal path avoids the direct activation of each preset, as you scroll through the preset list with the JOG WHEEL. Thus, the DSP1124P makes sure that no “unwanted” programs are loaded unintentionally. Additionally, you can rotate the JOG WHEEL at high speed and still have the time to specifically select the preset of your choice, instead of any of its “neighbors”. 7.2 Selecting the filter operating mode Each filter mode has two letters assigned to it, which appear in the DISPLAY after pressing the FILTER MODE key. The following display messages are available: Display OF PA AU SI LO Operating mode Off Parametric EQ Auto Single-Shot Locked Tab. 7.1: FEEDBACK DESTROYER PRO filter operating modes As already mentioned, the operating mode of a filter can be changed as follows: Press the FILTER SELECT key and specify the filter number (1 through 12) with the JOG WHEEL. Using the two ENGINE keys, you can select the left (ENGINE L) or right audio channel (ENGINE R), or both at the same time by pressing the two ENGINE keys simultaneously. Now, press the FILTER MODE key and select the mode of your choice with the JOG WHEEL. The display message “LO” (= “Locked”) informs you that a filter set to Single-Shot mode before is already suppressing feedback. As described in chapter 6.4, this filter is set to Locked mode automatically. You can unlock such a filter by switching it back to Single-Shot mode. As soon as a new feedback frequency will be found, the FEEDBACK DESTROYER PRO switches the filter from the old frequency to the new one. If you leave Auto or Single-Shot mode and enter parametric EQ mode, the filter’s parameter settings remain unchanged. 7. WORKING WITH PRESETS 15
