B. INTRODUCTION
InLine® Mobile AmpUSB HiFi DSD Headphone Amplifier is an ultra‐mastering grade digital
audio playback system. It is capable of converting high resolution PCM audio (up to 384
kHz) and DSD audio (up to 128x DSD). The DAC allows you to bypass your mobile phone’s
soundcard or headphone output and send digital audio signal through the USB interface.
With this perfect digital interface between your mobile phone and the music system, the
sound quality is pushed to another higher level in your overall music environment.
