The Nagra SD accepts a range of Nagra-made extra high quality Mono (omni-directional / cardioid) and Stereo (cardioid) clip-on microphones and is also delivered with an external mono XLR microphone cable allowing an external dynamic microphone to be used. Designed for radio applications, the NAGRA SD offers instant start-up, one button recording, automatic level control, internal loudspeaker and a low cut filter. A set of switches on the rear of the recorder give the user rapid acces to several important functions without the need to enter the menus.



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.
