Bootloader Switch Location 

The bootloader switch on the MAC Quantum Profile/Wash and the MAC Encore Performance/Wash is located inside the base of the fixture, on the main display 

Steps to Locate: 

1. Power off and unplug the fixture completely. 

2. Place the fixture on a secure, static-safe work surface. 

3. Remove the base cover by loosening the screws (typically Torx or Philips-head). 

4. Carefully lift the cover to expose the internal electronics. 

5. Look for a small tactile switch near the edge of the main display control PCB. 
    

• It may be located near the USB or Ethernet ports, or next to a firmware update header. 

• The switch is typically black or red and slightly recessed. 

Note: Use caution when handling internal components to avoid ESD (electrostatic discharge) damage. 

Use Case: Bootloader Mode 

Pressing and holding the bootloader switch while powering on the fixture forces it into bootloader mode, which is used for: 

• Firmware reinstallation via USB or DMX tools. 

• Recovering from failed firmware updates. 

 Warnings & Safety 

• Only qualified technicians should open and service the fixture. 

• Always disconnect power before servicing. 

• Ensure anti-static precautions are in place.
