Download (upgrade) firmware Mixer and Dsp
MixLite allows an update of the two programs in it inserted. One concerns DSP (Digital Signal
Processor) which deals with processing audio signals, the other concerns the
RISC (Reduced Instruction Set Computer) that deals with of the UI. These two files are of type "Wave"
(.wav, also described as "Media File"). The comunication therefore, is in an analog environment. No
digital port (RS232, USB, etc.) is necessary. The update
it can be executed, for example, by means of a common CD player.
If the filename contains the suffix ... DSP ... (if so they sequentially read the letters "... DSP ..."), it will
update the DSP.
If the suffix is instead ... AVR ..., the latter will update the RISC or the UI.
How to proceed with the upgrade
1) Hold the MixLite off.
2) Connect an audio cable to the analog output from which comes the Wave (PC, Mac or other). Note
that if the Wave is conveniently burned on audio CDs, too a common audio CD player is fine. In this
last case would be ideal to use the LINE output and not the headphone output. Choosing the channel
(Left or Right) is indifferent.
3) Connect the other end of the cable to the MIC 1 input MixLite. Ideally, you would use an XLR-type
connector (Cannon) for microphone, but also the Jack entrance well, a
provided the signal is very high in level. The cable can be mono or stereo (the Wave file is, however,
mono).
4) Lift the MIC channel 1 slider at most and lower the outputs to the minimum (since the audio signal
is very strong and unpleasant ...)
5) Now hold down the "Esc" and "Scene" while feeding MixLite through insertion of the plug into the
power connector (* figure Rear panel p.8). The display must a vertical line appears.
6) Running Wave (or Audio CD) beginning and wait for the text to appear on the MixLite display
"LOAD OK". The update was at this point successfully completed.
NOTE:
_When finished with the update via Wave, if you read the word "ERROR" or you still
see a vertical line, it means the link is not correct or the Wave has been reproduced
at a level too low.
_If you use a PC, be sure to raise all levels to maximum, even those inserted in the
multimedia mixer, usually present in the lower right bar of Windows.
_The procedure for upgrading DSP and AVR is the the same, and should be executed in
that order.
