The Pulse unit has three internal
points for firmware. The display board or MCU
is responsible for your Menu, Display, Volume control, and IR port. This can
only get updated in-house.
The USB firmware is responsible for the musical data communication. It
controls the USB sampling, DSD over PCM, PureDSD and all other music data
formats. This can be seen using the Light Harmonic Control Panel.
The Main firmware is the overall architecture for the display,
processor, and DAC communication. The only firmware that cannot get updated in
the field is the MCU or Display Board.
By using the Device Firmware Update utility or DFU you can flash your Pulse with the latest updates via USB.
Our Firmware breakdown table will show you all of our
current firmware for all three major points.
