A corresponding red LED, located to the right of the
display window, will turn onbased on selected input
type: “TOSLINK” (for “D6” and “D7”) , “S/PDIF”
(“D3”, “D4” and “D5”), “AES/EBU” (“D1” and “D2”)
or “USB” (“D8”). Note: you cannot connect a USB
flash drive or external hard drive to the “D8” input.
If your Nēo 380D is equipped with the optional
“MiND” music streaming module, the assigned input
is “D9”, the sampling rate will appear in the display
as it does for inputs “D1” thru “D8”, and the red
“NETWORK” LED will illuminate.
Rear Panel Connections
Figure 2: Nēo 380D Rear panel
The rear panel will look similar to Figure 2 (above).
On the left side are two rows of analog outputs; The
bottom row has two pairs labeled “Right” and “Left”,
each with a single-ended RCA and balanced XLR
connector. These are “Fixed Level” outputs,
intended to be connected to a line-level input on
either your preamplifier or integrated amplifier. The
top row also has two pairs labeled “Right” and
“Left”, each with a single-ended RCA and balanced
XLR connector. These are the OPTIONAL “Variable
Level” outputs, whereby the volume level can only
be adjusted using the included remote control.
These are meant to be connected directly to your
power amplifier’s input; They can be also connected
to a line-level input on either your preamplifier or
integrated amplifier. We strongly recommend that
you use the balanced XLR connectors on your 380D
to maximize its level of performance. Don’t hesitate
to use high quality interconnect cables*. Poor
quality interconnect cables can degrade the overall
sonic performance of your system.
There is one “Digital SPDIF Output” on an RCA
connector, immediately followed by the SPDIF digital
“Monitor Loop” with one input and one output, both
on RCA connectors. Next is a group of eight (8)
“Digital Inputs” labelled “D1” thru “D8”. Inputs “D1”
and “D2” are AES/EBU on 3-pin XLR connectors and
they benefit most from cables with an impedance of
110
Ω. Inputs “D3”, “D4” and “D5” are S/PDIF – the
first two on RCA connectors and the third on a BNC
connector, benefitting most from cables with an
impedance of 75
Ω. Inputs “D6” and “D7” are Optical
and use a Toslink connector. Finally, input “D8” is
USB type-B connector. Don’t hesitate to use high
quality digital interconnect cables*.
The space directly above the row of digital inputs is
reserved for the optional “ MiND” Music Streamer. If
your Nēo 380D is equipped with the “MiND” option,
you will see a socket for a WiFi antenna and a RJ45
ethernet connector socket. Please consult the “MiND
Setup Guide” and “MiND User Guide” for further
details.
The upper right side of the rear panel has various
connectors for external communications. The Nēo
380D is equipped with full-function bi-directional
RS-232 port control and status for custom
integration or automation, as well as future software
updates. Next to the RS-232 port are two (2)
“SimLink™” connectors labeled “in” and “out” on
1/8” mini jacks. Please refer to the next section
entitled SimLink™ for more details. Then there is a
1/8” mini-jack input for use with aftermarket
infrared remote control receivers. Finally, there’s a
12V trigger output on a 1/8” mini-jack. Finally on the
