Upgrading If Current Firmware Is 1.23 Or Above - Audiophilleo Audiophilleo1 Owner's Manual

A U D I O P H I L L E O 1 & 2
 LSSLL means that the firmware file is identical to the already loaded firmware.
No update is possible.
 LSSSLL means that the firmware file was corrupt. Most likely the computer is
modifying the audio stream. Please check that you are using a 44.1 sample rate
without re-sampling and other distortive effects happening on the computer.
AP1 Note
: After a failed firmware update, unplug and re-plug the ap1 or re-enter the
firmware menu with ap1. No updates may be possible without doing this.

Upgrading if current firmware is 1.23 or above:

A few simplifications were made to the LED messages in order to make it easier to
follow the messages:
1. Unplug the ap2 USB port
2. Plug in the ap2 USB port
3. Wait between about 5 to 30 seconds (settings are not detect after 45 seconds of
power-up)
4. Play the firmware.wav file using your favorite media player.
5. Within a few seconds the LED should turn on solid (no blinking messages).
NEVER power cycle the ap2 when the LED is on solid. This means that the
firmware file was detected and that you can continue to step 6. If the LED
does not do this, it usually means that the media player software is modifying
the WAV file too much for the AP2 to recognize it (not using 44.1/24,
resampling, applying volume control, EQ, etc.). Please double check all
settings and re-start the procedure from the beginning.
6. After being solid for about 10 to 20 seconds, the AP2 will reboot with the new
firmware and show LSSLL (Firmware Updated).
disconnect the AP2. If an error occurred, the ap2 does not reboot but shows
LSSLL (Firmware already up to date) or LSSSLL (Firmware file is bad. In this
case you should restart from the beginning).
