There has been an update, which brings the DSEE HX AI function to both
WM1A/Z+ and
WM1A to 1Z mods.
The DSEE HX AI function replaces the "Standard" option from the DSEE HX effect type menu. This function is
present in devices like the NW-A55, or the DMP-Z1.
Official description:
DSEE HX (AI, or not) works only for CD quality audio, or lower. DSEE HX will not have an effect for audio with
a sampling frequency over 44.1kHz or 48kHz, like "24 bit/96kHz".
DSEE HX (both AI or the other options) also works with the Bluetooth receiver or the USB DAC functions.
You can "see" the function in action by switching the visualizer to "Spectrum Analyzer", and monitoring the "HIGH"
spectrum of the sound.
There are also some improvements to the integrated switcher, and all the languages were updated to reflect the
DSEE HX AI function replacing the "Standard" option of the DSEE HX effect type menu, as well as the "Switch Device
Model" replacing the "Factory Reset" function.
Do I need to first switch back to stock before installing this?
No. Like always, this works like any other firmware update. Just install it and that's it.
