Nakamichi 7.1 Preamp/Surround Processor
The Nakamichi AV1 is our latest developed home theatre AV preamp that supports HDMI 1.4 standard. The Nakamichi has 7.1 channels output, which supports the most advanced HD audio encoding technology, including Dolby TrueHD™ and DTS Master Audio™. AV1 has multi-zone amplifier output control, which means that aside from the main zone it can amplify and control 3 additional stereo zones concurrently.
Using the Nakamichi AV1 is easy, for the beginner it is a matter of connecting all your sources, plugging in the calibration mic (included in the box) and using the calibration room correction software to automatically adjust your system to your room's acoustics. We have however not forgotten the audiophile and included a large array of options to configure the system so your own listening tastes.
