A new firmware update is available for the Pioneer XDP-100 portable digital audio player. The new microprogram allows users to extend the DAP’s capacities in order to listen at higher volumes. Once the update is launched, simply open the Settings menu, choose ?Sound and Notifications? and activate the ?Variable Line Output? mode. The device will automatically reboot to take the new settings into account. If you haven’t yet familiarized yourself with this DAP, we invite you to read our review of the Pioneer XDP-100.
