Introduction 
 
Thank you for selecting the MOON Nēo 380D
Digital-to-Analog Converter (DAC) as a part of your
music/cinema system. This component has been
designed to offer state-of-the-art high-end
performance in an elegant package, while retaining
all the sonic hallmarks on which Simaudio has made 
its reputation. We have spared no effort to ensure 
that it is amongst
the finest
DAC’s available in its
class. We have been building high-performance
audio equipment for over 30 years, and the
know-how gained through our cumulative 
experience is an important reason why MOON DACs 
are so musically satisfying. 
 
The performance of your Nēo 380D will continue to 
improve during the first 400 hours of listening. This
is the result of a “break-in” period required for the
numerous high quality electronic parts used
throughout this DAC. 
 
Before setting up your new 380D, we encourage 
you to please read this manual thoroughly to
properly acquaint yourself with its features. We 
hope you enjoy listening to the Nēo 380D DAC as 
much as the pride we have taken in creating this
fine audio product. We understand the power and
emotion of music and build our products with the
goal of faithfully capturing these elusive qualities.

Your Nēo 380D Digital-to-Analog Converter incorporates many significant design features to achieve its “world
class” level of performance. This is an abbreviated list of the more important features: 
 
ESS Technology SABRE
32
Ultra DAC/Digital Filter
working in 32-bit Hyperstream™ to achieve 
unprecedented jitter immunity and low-level linearity via a 
patented Time Domain Jitter Eliminator. 
Digital Audio Signal Processing using M-AJiC32 (MOON 
Asynchronous Jitter Control in 32-bit mode) 
Eight (8) digital inputs (AES/EBU x 2, S/PDIF x 3, 
TosLink x 2 and USB x 1) allowing for a connection to 
virtually any digital source, along with one (1) digital 
output – S/PDIF. 
Optional “MiND” (MOON intelligent Network Device)
module (9
th
input) via WiFi or Ethernet input for multi-
room streaming.
Optional variable analog outputs (balanced & single-
ended) using M-eVOL volume circuit which was originally 
developed for the MOON Evolution series. Accessible using 
the remote control, this volume operates in 1dB 
increments. M-eVOL is based on a resistive array 
configuration with no sonic degradation of the audio signal 
at all volume settings. 
Full digital monitor loop on S/PDIF to accommodate 
external devices such as a room correction component. 
 
Separate digital and analog power supplies, each 
using a toroidal transformer and 11 stages of voltage 
regulation. 
“Dual Jitter Control System” producing a digital signal 
that is virtually jitter-free, measuring below “1 picosecond” 
as well as ensuring compatibility with virtually any digital 
device. 
USB input with galvanic isolation which eliminates all 
ground current (i.e. no electrical connection) between the 
USB device (computer,music server, etc) and the 380D, 
preserving the accuracy of the audio signal. 
RS-232 port for (i) full unsolicited bidirectional feedback 
and (ii) firmware updates; 12 Volt trigger output for 
remote operation; IR input for external control with 
aftermarket infrared remote control receivers and 
SimLink
TM
controller ports that allow for 2-way
communications between other MOON components.
Rigid chassis construction to minimize the effects of 
external vibrations. 
Designed to be powered up at all times for optimal 
performance.
