   When connecting to audio source devices with 3.5mm headphone jack, user can use the adapter plug for transferring output.

USB Input Mode

USB interface chip in the A300 is a XMOS ch ip commonly used by high-end audio equipments. After being connected to PC, USB interface will directly extract and play back digital audio signal in a manner similar to the “USB external sound card”, to avoid sound degradation and dynamic range compression caused by digital-to-analog conversion of PC sound card, and to ensure the restoration of original sound quality.

• PCM audio signals (44.1KHz/48KHz/96KHz/192KHz) only functions in USB mode.
• If connecting the speakers to a PC, driver program must be installed first for system to perform properly.
• USB driver in Mac operating system supports USB Audio Class 1 and Class 2 audio transmission by default, therefore driver program installation is not needed.
