Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor
10
Attack (A__ms) and Release (R__ms) settings adjust the time it takes the limiter to engage and then disengage
when the signal increases above threshold and then subsequently falls back below threshold. Attack time is adjustable
from 0.5ms through 50ms, while release time ranges from 10ms through 1s. A very fast attack time can sound unnatural,
while a very long attack time can miss some of the initial transient. Similarly, a very short release time can make the audio
sound uneven, while a very long release time can create "pumping", or "breathing" characteristics depending on the kind
of signal. Experiment to find the best solution for a given application.
4.7 Other Functions
The Protea 3.24CL has a full complement of non-
audio functions within a single keystroke to navigate around
the product quickly. Recall, Save, Copy, Mute, and a Utili-
ties menu complete the user interface.
4.7a Recall
There are 30 stored presets which can be recalled on
the 3.24CL. Note: A preset recall will overwrite the working settings, so make sure the current configuration is saved
before continuing or it will be lost. Remember, an unsaved working preset shows (
modified
) on the preset name screen.
Press Esc to see the preset name screen. The 3.24CL always loads the working preset on power-up, so as to preserve any
changes should the power be inadvertently turned off prior to saving.
Ashly includes 10 default preset templates in the 3.24CL as starting points for common configurations. These
first 10 presets repeat from 11 to 20, and again from 21 to 30, and can be edited and saved as desired. To recall a new preset,
press the recall button once, select the desired preset number, and press recall again. At this point the LCD display
prompts the user to mute the outputs or not, and selecting Yes or No will load the new preset and mute all outputs if so
desired.
A new preset may have dramatically different settings capable of damaging sound system components, so be
careful not to recall the wrong preset while the system is on.
To be safe, always select "Yes" to mute all outputs.
4.7b Save
Once the 3.24CL has been adjusted to suit the application, the changes can be permanently saved to memory*.
To save a new configuration or save changes to an existing preset template, begin the process by pressing the Save
button once. The LCD display prompts for the new (or same) preset number, and after selecting the desired number press
Save again. At this point the name of the preset can be changed by selecting any one of the 20 text characters and
scrolling through the list of 89 available ASCII characters for each. Pressing the Save button again permanently stores the
working preset to the new preset location.
*Note: performing a Factory Reset will erase all user presets and replace them with the ten original Ashly
preset templates.
4.7c Copy
The Copy function is used to quickly transfer all settings from a currently selected input or output to another
input or output channel. An example of how this might be used is with stage monitors. Suppose there are six monitor
mixes on stage, and they all use the same type of floor wedge. The first monitor could be set up with Gain, EQ, and
Limiting, then those settings could be quickly copied to the remaining five monitors, providing a consistent starting point
for each mix. To copy, first select the input/output to copy from, then press the Copy button, then press the input/output
to copy to, pressing the Copy button a second time to complete the action.
