1 PRODUCT OVERVIEW
The nanoAVR HD and nanoAVR HDA HDMI audio processors provide a comprehensive and sophisticated set of
digital audio processing functions for eight channels of high-resolution (24-bit, 96 kHz) HDMI audio. The
functions include bass management, parametric equalization, level adjustment, mixing and routing, and time
delay. All internal processing takes place at 96 kHz, with sample rates up to 192 kHz accepted over HDMI.
Two HDMI inputs are provided and can be switched from the front panel or by an infrared remote (not
included). The accepted audio format is multichannel linear PCM (LPCM). Video from the selected HDMI input is
switched directly to the output, with no video processing applied to the signal.
A user-friendly computer-based interface is used to configure the audio processing parameters of the nanoAVR
in real time. Up to four complete configuration presets can be stored. Once configuration is complete, the
computer is no longer needed and the presets can be recalled from the front panel, by an infrared remote, or
with a smartphone app.
1.1 TYPICAL USAGE – NANOAVR HD
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.
The HDMI output is connected to an A/V receiver, which in turn drives the display (TV, monitor, or projector),
powers a suite of loudspeakers and provides output to a subwoofer.

1.2 TYPICAL USAGE – NANOAVR HDA
The nanoAVR HDA negates the need for an A/V receiver to decode the audio component of the HDMI stream.
For example, the analog outputs of the nanoAVR HDA can be connected directly to a multichannel power
amplifier and a powered subwoofer, as illustrated in the diagram below. 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.

2 INSTALLATION AND S ETUP
2.1 HARDWARE CONNECTIVITY
All connections to the nanoAVR are made on the rear panel.
2.1.1 HDMI input and output
Two HDMI connections are available for input, and one for output. The input connectors can be connected to
any HDMI source such as a Blu-ray or DVD player. Other sources may include media streaming devices, gaming
consoles, and computers with an HDMI port†.
The HDMI output will need to be connected to an HDMI input on an A/V receiver (AVR) or A/V processor (AVP).
In the case of the nanoAVR HDA, the HDMI output can be connected directly to the display device (TV, monitor,
or projector).
Ensure that your HDMI sources are set to produce linear PCM (also referred to as PCM, L-PCM, or LPCM)
on their HDMI outputs. The nanoAVR does not decode compressed formats such as Dolby and DTS.
Some HDMI devices such as TVs only support basic HDMI Audio (up to 48 kHz), and will not respond to
audio from the nanoAVR. 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.

2.1.2 Analog outputs (nanoAVR HDA only)
The analog outputs of the nanoAVR HDA can be connected directly to power amplification and a powered
subwoofer. They can also be connected to any other equipment with multichannel analog inputs such as an A/V
receiver, multichannel preamp, or mixing desk.
Note that HDMI audio and the analog outputs are simultaneously active.
Always be sure to turn off all equipment before connecting or disconnecting audio signal cables.
miniDSP Ltd , Hong Kong / www.minidsp.com / Features and specifications subject to change wi thout pri or noti ce 12
2.1.3 DC Power
The supplied 5 VDC power supply includes a set of interchangeable power pins. Fit the correct pins for your
country. Connect the DC plug to the 5 VDC power socket.
HDMI units communicate with a set of “hand-shaking” signals in order to establish the capabilities
of each device. It is recommended that for at least the first time the system is powered up with the
nanoAVR connected, equipment is powered on in this order: TV, AVR, nanoAVR, source/player.
2.1.4 USB
To configure the nanoAVR via USB, connect the USB port of the nanoAVR to a USB 2.0 port on your computer
using the supplied cable.
miniDSP Ltd , Hong Kong / www.minidsp.com / Features and specifications subject to change wi thout pri or noti ce 13
2.1.5 Ethernet
To configure and control the nanoAVR over Ethernet, connect an Ethernet cable from the nanoAVR’s Ethernet
port to a free port on your Ethernet router or switch. The diagram below illustrates a typical case where the
Ethernet router also acts as a wireless base station, and is in turn connected to an ADSL/cable modem. It is also
common for the ADSL/cable modem, Ethernet router, and wireless base station to be combined into a single
unit.
In the setup illustrated, the nanoAVR is connected via an Ethernet cable to the Ethernet router, while the
computer is connected to the LAN over Wi-Fi. The network must be capable of DHCP so that the nanoAVR will
be given an IP (network) address.
If a local area network is not available, or the network does not support DHCP, it is still possible to communicate
with the nanoAVR over Ethernet by connecting the two devices directly with an Ethernet cable. In this case,
auto-IP (link-local) addresses will be assigned. For this to work correctly, your PC must be set to allow automatic
IP addresses (that is, it must not be set to a static IP address).
