Compatibility
兼容性
The Nagra SD has a miniature USB 2.0 port. Through this connection, the internal memory appears on the “desktop” as a mass storage device (external drive) of the PC / MAC and requires NO additional software or drivers. It can also be connected to the NAGRA LB for file editing and transfer operations in-the-field if desired.
