Any modifications made to that preset before saving it will remain in the working preset until either the modified preset is saved, or a fresh preset is recalled to the 3.24CL. When modifications to an existing preset are made without saving, the display adds the text (modified) after the preset number. -

EQ problems. Protea 3.24CL parametric filters have a boost/cut range of +15dB to -30dB. There is more cut than boost because one of the more common uses for parametric filters is to dramatically cut, or "notch out", very narrow frequencies (low bandwidth) in order to eliminate system feedback problems. -

The steeper the slope, the more abruptly the "edges" of the pass band will drop off. There is no best filter slope for every application, so experiment to see which one sounds most pleasing in a specific system. Ashly factory default presets use all 24dB/octave Linkwitz-Riley filters in the crossover section, but of course they can be changed to suit the application. -

Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 24dB/oct Linkwitz-Riley filters are the industry standard, the easiest to use, and the filter type recommended by Ashly. Other filter types are available, but may require polarity switching or other adjustments for proper results. The following paragraphs offer a summary of the three filter types as used in the 3.24CL crossovers. -

Mute button, pressing it a second time to confirm. Additionally, when recalling a new preset number to the 3.24CL, the LCD display prompts the user to mute all outputs, as a new preset can introduce dramatic changes to the system configuration. -

Excessive Noise - An input signal level or an input gain setting that is too low could require the loss to be made up for at the output gain stage, producing more noise than a properly set up gain structure. Do not use the 3.24CL for dramatic increases in level, but rather optimize the signal source for a nominal 0dBu output. -
