The miniDSP  nanoAVR DL  integrates the world-renowned Dirac Live® room correction algorithm into a palm-sized HDMI audio processor. The onboard floating-point SHARC processor allows complete frequency and phase correction of a 7.1 home theater or multichannel audio system. The results from deploying Dirac Live® are remarkable: improved imaging and soundstage; greater clarity of vocals and dialog; smoother and more impactful bass; heightened realism. Last but not least, our free Android and iOS App provide live control of basic settings such as volume/mute/presets. An all in one control remote from your tablet/phone. Simply put: a better home theater experience!

STOCK UPDATE( Nov 2019): NanoAVR platforms are unfortunately now out of stock due to  IC shortage. Stay tuned for update.

Application notes on nanoAVR DL

Two popular methods of room correction are Room EQ Wizard (REW) and Dirac Live™. In this application note, we will compare and contrast these two methods. miniDSP has several products that incorporate the Dirac Live algorithm, including the stereo Dirac Series, the multichannel DDRC-88A and nanoAVR DL, and the forthcoming compact miniDSP 2x4 DL.

  with Dirac Live - Key Features

Please note: the nanoAVR DL does not contain an embedded Dolby/DTS decoder
and therefore only accepts linear PCM (LPCM) audio streams. Please make sure 
that your player/source can be set to provide multichannel audio as linear PCM.

An inmediate and easy set-up for a home theather system, with really GREAT results in sound. This little black box brings magic to a multichannel system. Highly reccomended.

nanoAVR DL (Jan 2015)

It takes a lot of energy and effort to write a review as extensive as the one Jeff did for the nanoAVR. Certainly worth your time reading, though once again you might need to brush up your French first... :-) Make sure to use Google translate first.

The NanoAVR DL is a pretty amazing product. Surprising, because given its small size and simplified design, it achieves performance of the highest level. Compete and surpass the Audyssey XT32 is no small feat. MiniDSP again demonstrates they know DSP with this powerful acoustic correction system

The HomeTheaterShack community and the great team behind it goes at great length to review products. Reading from the lengthy but well written technical reviews from Wayne Myers, we can only guess that it too a lot of time and energy to fully evaluate the product.

nanoAVR DL review (June 2015)

I simply have to say my experience reviewing these products has been one of the most positive I have had to date. This is simply a phenomenal product, and, where it fits one's system configuration needs, I can think of no reason it should not be at or near the top of any serious listener's purchase list, if they do not have one already
