The Nagra VII Anniversary Edition is the celebration of the 70th anniversary of the creation of the very first Nagra in 1951!
Electronically identical to a Nagra SEVEN, its front panel is totally new and built from a solid billet of aluminum. All the buttons are made of aluminum, including the potentiometer that are red and green as a testimony to the legendary Nagra IV-S.
The battery compartment is also made from a solid block of aluminum.
The whole construction is super rugged and also a pleasure to feel.
Sonically the Nagra VII is the son of the Nagra V and Nagra VI that found their roots on the Nagra IV-S. Its microphone preamplifiers are super transparent and silent. They can be compared to the best stand-alone microphone preamplifiers and can very well be connected to large membrane studio microphones. The A/D and D/A are capable of 192 kHz / 24 bits that will make your musical recordings shine. The Nagra VII is very intuitive and was designed with the sound engineer in mind. It takes a short training period to know how to operate it and be efficient in your work. Having a dedicated recorder is a huge advantage as it allows the sound engineer to focus on sound and quality of the recording.
The VII Anniversary offers two analog audio inputs and a single stereo digital input. It will record in PCM linear audio at sampling frequencies up to 192 kHz or in MPEG-1 layer II compressed audio formats if the compression option is installed. The inputs are equipped with traditional Nagra microphone preamplifiers for dynamic and phantom +48V microphones and offer a range of switchable sensitivities to accommodate all common microphones. AES-42 microphones can also be used as the recorder can supply the necessary 10V dc supply voltage on the AES input. The analog LINE input will accept up to +24dB, allowing it to be connected to a standard audio mixer in the field.
