It doesn’t let me use the app some Chinese letters come up and can’t manage to make them go away I already deleted and installed the app again and they still come up. It Might be a Bug or something but that needs to be fixed

Getting Better

Been using the DEQ-S1000A since Crutchfield added it and have been mostly satisfied. They seem to be updating with more features regularly. One thing I wish would be added is to be able to attach a preset per source. Since I am using this to fix my factory EQ AND sometimes direct play their is a huge difference in sound between the sources and I have to change presets every time. Hopefully the developers read the reviews and can look into a way to add this feature. Also their is a ton of work needed to make the calibration better, it seems to do nothing.
