AC650 Firmware Updater

Before You Begin

Prepare your amplifier for the firmware update.

1
Open the amplifier
Remove the four M3 bolts from the top panel using a 2 mm hex driver (Allen wrench).
Lift off the top lid to expose the circuit board.
2
Locate the USB port
On the circuit board you'll see two small buttons labeled RESET and BOOT, and a micro USB port next to them.
3
Connect the USB cable
Plug a micro USB cable into the port on the board, and the other end into your computer.
4
Connect main power
Make sure the amplifier's main power cord is plugged in. The amp does not need to be turned on — just connected to power.
