44.1/24, then iTunes will again resample once the AP is plugged in. To avoid this,
temporarily change the sample rate of your internal audio device to 44.1/24 as well.
Note
: If your current firmware version is 1.15 or less, please be sure that the
firmware.wav file plays only once and that nothing else plays after it.

Audiophilleo1 Update Procedure

The firmware->about screen will show the currently running firmware version. To
update, simply go to the firmware->update screen and follow the directions. You will
play back our firmware file using your favorite media player and the update will happen
automatically, showing progress from 0% to 100%. This takes about 4 seconds. If you
do not see this progress, then it means that the firmware file was not recognized.
Please review this chapter and retry. If everything works, the Audiophilleo1 reboots
and will show the status message "New Firmware". Additionally, the messages
"Defaulted Settings" and "Defaulted Remote" mean that the settings or learned remote
control codes have been reset to defaults. This is done only when the new firmware
requires it. You may also use the about screen to verify the new firmware version.
Note
: If there are errors during firmware upload it likely means that that the computer
is modifying the audio stream. Please exit and re-enter the firmware->update menu
before playing the firmware file again.
Note
: The ability to perform a firmware update does not mean that your audio stream
is BitPerfect. The firmware file is encoded in a way that allows it to survive limited
modifications to the stream.

Audiophilleo2 Update Procedure

Unlike the Audiophilleo1, the Audiophilleo2 does not have an OLED screen so you
need to pay close attention to the LED codes in order to follow the progress of the
update. Please see the section on LED codes for details on the codes.
Note
: If your Audiophilleo2 has the PurePower option, then the PurePower needs to
be connected to and powering the Audiophilleo2 in order to perform an upgrade.
