Navigating and Adjusting Parameters with the Onboard GUI
It is possible to adjust most parameters of the APA1200DSP on the unit itself via the display and control knob. For initial
setup of the device, it is recommended to connect to the web-based GUI (see the next section), as the onboard GUI is
better for making quick adjustments on the fly, rather than many adjustments at once. For more information about each
menu option and parameter type, see the corresponding sections later in this guide.
Instructions:
1. Rotating the dial will move to the next menu option or increase/decrease a value depending on the current
context of the menu. The currently selected parameter will be highlighted.
2. Pressing the dial once selects a given parameter or advances further into the menu (go forward).
3. Quickly pressing the dial twice returns to the previous page or previous level of the menu (go backward).
For example, if you are in the PEQ menu, you will click the knob once to select a parameter such as frequen-
cy. You can then rotate the dial to change this frequency. When you are done, press the dial twice to go back,
allowing you to select a different parameter to change.
4. Long pressing the control knob in the menus of volume, LPF, PEQ, HPF, Phase Degree and limiter will allow
you to ‘link’ the A and B channels together, which means that all parameters within the menu will affect both
channels. Long pressing again will allow you to ‘unlink’ the channels and create individual settings for each
channel.
