Nagra Trots Out Mezzo & Seven Portable Digital Recorders

Nagra has debuted two new digital recording products, the Seven and the Mezzo. The Seven is a portable two channel recorder with a modular design, allowing it to be a recording ninja and adapt to a variety of field applications. The concept was to build a quality 2-channel recorder that offers modern features not otherwise seen in battery operated on-the-shoulder type recorders with an intuitive interface.
The audio inputs are equipped with user-programmable audio limiters, an AGC system and digital filters. This new concept allows not only cleaner ALC and Limiters, but also simplifies the design of the preamplifiers making the audio path more direct. The onboard operation system has also been further refined highlighted by a modern, sunlight-readable, color touchscreen.
