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

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:
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.
