Hello.
My problem is with a Hercules DJ Console 4 Mix.
When I connect the USB, the headphone button lights up for a moment, then fades out.
That's all it does.
Windows doesn't recognize it; after a while, the unknown device message appears.
I've tried several PCs, reinstalling the drivers, and nothing.
Even on the PC I always use, the same thing happens.
Everything points to a physical problem.
I've disassembled the mixer and checked voltages and everything else I couldn't find without any information (I'm an electronics technician).
If possible, I would appreciate technical information and a schematic of this mixer.
Personally, I think the firmware has been corrupted, so I'd like to know if it's possible to get the file to reprogram the memory.
I have the means to program the chip.
I'm delighted with this mixer and would like to be able to repair it, so I would appreciate any information.
Thank you very much in advance.
Hello CG2,
You do not describe the computer & operating system on which you have connected your DJ Console 4-Mx, but if your situation is the one mentioned on DJ Console 4-Mx download page, https://support.hercules.com/product/djconsole4mx/ in the warning on top of the page
If your computer PC/Mac with USB 3 ports does not detect your DJ console:
Test your DJ Console on a PC with either Windows 7 or Windows 8.0, or with not any USB 3 port.
Open the Hercules DJ Control Panel, go to the About tab and check the Firmware version.
To work on computers with a USB 3 port, the firmware version must end with 16 on DJ Console 4-Mx
and DJ Console 4 Mx unit has its firmware either bricked (not readable = the controller cannot boot) or too old, then the solution is to update the firmware.
If you have already disassembled some part of the electronics, you may
- remove the eeprom from its socket (on the printed circuit board where you see the USB connector)
- to program the firmware in the eeprom with an eeprom burner.
Please confirm if you have an eeprom burner (either a basic one as CH341A based programmers, or a more sophisticated model) and know how to use it, and then I send you the bin file to program in DJConsole 4-Mx eeprom.
