Exos-9 Firmware Update to remove Compressor effect
The Exos-9 has onboard firmware that controls the operation of the bluetooth
functions as well as some DSP that subtly affects sound quality.
You can update the firmware through the micro-USB port on the back of the Exos-9.
The Exos-9 ships with firmware that includes a DSP dynamic compressor. This feature works by leveling off more extreme peaks in the audio, and is implemented as a conservative safety measure for the drivers and power circuit of the speaker. However, sometimes this feature causes a subtle, but noticeable effect on the audio, and some users prefer the audio without it.
If you would like to remove the compressor feature, here's how to do it:
1) You will need to do this using a Windows PC. Unfortunately at this time, we don't have OSX-compatible drivers.
2) Download the new firmware. This .ZIP file contains the new firmware that removes the compressor effect. Extract the files to the desktop or somewhere you'll be able to find them easily.
3) Connect the speaker to your computer using a micro-USB to USB-A cord.
4) Turn the speaker on.
5) Find the .BAT files that you extracted from the .ZIP file. Double click the "H40001_20170831_EQ_ONLY.bat" file first. (Windows may give you a warning about the file being from an unknown publisher. This is OK, press "more info" and then "run anyway".) A black window will come up, and eventually it should finish running and eventually show 100%.
6) Once the first .BAT file has finished, double-click "H40001_20170831_New_Compander.bat" and allow it to run. It should also finish running and show 100%.
7) Turn the speaker off using the switch on the back, and disconnect the USB cable.
8) Turn the speaker back on. Congratulations, you've upgraded your firmware!

Warning! Don't turn the speaker off while the .BAT files are running - this has the potential to break your speaker!
