Question I use my Nova System in Preset Mode directly into a P:A: Mixer. I´d like to set Nova EQ global for all my presets, i.e. to push frequencies round 800 Hz. If I press EQ Button it says EQ n/a. Why Answer When EQ shows "n/a" it is because you have activated the speaker emulation, which is the right thing to do when connecting to the PA mixer. The speaker emulation uses the EQ block and therefore the EQ is not available. If the simulation does not fit your taste, you can disable it and  set the EQ yourself.  You can set the EQ in one of your preset and store the settings, then while you are on that preset, go to utility and set EQ lock to ON - The same EQ will be used in all presets.
