1.66A).
You can also power up your AudioFuse directly with the USB cable, this will start the
AudioFuse in Bus powered mode which will slightly reduce the maximum level to +18 dBu
instead of +24 dBu. A special Low power mode is activated by software to reduce power
consumption and extend your laptop ,computer or phone's battery life
DC Powered Bus Powered Low Power
Number of Analog Input 4 4 0
Number of Analog Output 4 4 2
Max Input Level +24dBu +18dBu -
Max Output Level +24dBu +18dB +18dB
Phantom Power Voltage +48V +48V -
The AudioFuse also powers the USB hub up to 1A per USB plug, and your phantom 48V
powered microphones. USB hub functionality is disabled when AUDIOFUSE is only usb-
