Page 9: Product Overview
YPICAL USAGE NANO In its most typical application, the nanoAVR HD connects between an HDMI source such as a Blu-ray player and an A/V receiver, providing an unmatched level of audio tuning flexibility for home theater applications. The second HDMI input allows connection of a second device such as a media streamer or computer/HTPC. -
Page 10: Typical Usage - Nanoavr Hda
In this case, volume control is done digitally in the nanoAVR HDA itself, using a remote control or the miniDSP smartphone app. The analog outputs of the nanoAVR HDA can also be connected to multichannel analog inputs of an A/V receiver, A/V preamp, or any other component with multichannel analog inputs. -
Page 11: Installation And Setup
Use an A/V receiver or preamp with 96 kHz support to decode HDMI audio. † Apple Macs with a Thunderbolt port can be connected to the nanoAVR with the use of a Thunderbolt to HDMI adapter cable. miniDSP Ltd, Hong Kong / www.minidsp.com / Features and specifications subject to change without prior notice... -
