While the RM4200D is running, the current state of the system is stored in the Parameter Memory . Among the stored information are the current bus assignments of signals, the filter settings, the current values of faders and the assignment of available fader channels to the physically available faders. As these parameters change – e.g. the mid frequency of a filter – the corresponding values in the Parameter Memory change as well. (see also Parameter Memory)

The current state of the Parameter Memory can be “frozen” and saved as a kind of “Snapshot”. This set of data is called Setup.

The memory segment “Setup” is not available on all microcontrollers, but only on the Communication Controller RM420-850. All other modules read the necessary information from there. This segment is also located in the flash memory, thus retaining its information also after switching off the device.

Figure 57: Audio parameters are stored in the “Setup” memory segment.

All data of the “Setup” memory segment can be loaded or overwritten during operation.

	Tip
	If yould like to know exactly, which data are stored in the setups , find out more in chapter 3.6 (“Worth knowing on Setups”) in Part 6 of this manual Application Software.

In the Setup memory segment, Mixer Setups as well as Channel Setups are stored. A Mixer Setup contains data for all configured fader channels of a system, whereas in a Channel Setup, only data of one single Fader Channel are stored. As a whole, a maximum of 7 Mixer Setups and 250 Channel Setups can be stored.

	Note
	Setup 0 or “Default Setup” has a special function: It is loaded on a software reset or if the content of the Parameter Memory is invalid when the DSP frame is switched on. Therefore, you can write Setup 0 using the Maintenance Window only, not from the mixer console! (see also Memory Access at System Reset)

Using the Maintenance Window of the Toolbox4 software, you can access the Setup memory segment and save or delete setups. You can also define keys on the console, which you can use to store and load setups. Setups can also be stored on chipcards and can be read from them, if a card reader is available in the console.

The most convenient way to setup management is a special software, the Setup Manager. This application comes free with every RM4200D. You can also obtain it from your DHD dealer or directly from DHD.
