Support Windows7\/8\/10\/11\u30101\u3011, Mac OS, Android\u30102\u3011, iOS\u30103\u3011<\/p>\n
With a proprietary ASIO driver (only for UAC2.0), it supports ultra-low-latency ASIO playback and game modes.<\/p>\n
\u30101\u3011Windows 7\/8 must install the proprietary ASIO driver, while Windows 10\/11 can use the UAC driver that comes with the system, or install the proprietary ASIO driver.<\/p>\n

\u30102\u3011The Android device needs to support OTG and UAC2.0.<\/p>\n
\u30103\u3011Apple Lightning to USB adapter is required for connection. Since the Apple mobile phone has a current limiting mechanism, when the USB output current approaches or exceeds the limit point, it will limit the current, pop up a window or disconnect the device. HA200 has a large output power characteristic. Under the condition of high volume during use, it may cause the current limit of the Apple mobile phone, resulting in intermittent sound or automatic disconnection. The volume can be adjusted appropriately for use.<\/p>\n
