Digital + Analog Connectivity
Touchscreen & Remote Control
Direct Digital Technology: NAD's Direct Digital technology
is unique in both its extreme precision and in its speed. Direct Digital
technology uses a very powerful processing engine that operates at much higher
speed and with much greater accuracy than typical Digital-to-Analog converters.
Running at 108MHz, the M12 resamples the incoming pulse code modulated (PCM)
signal and converts it to a pulse width modulation signal (PWM) with a sampling
rate of 844kHz. Operating in a differential mode with double precision, the M12
has state-of-the-art specifications for low noise and distortion free sound. The
extreme headroom afforded by the 35-bit architecture allows for a DSP-based
volume control that does not reduce resolution. Even with 24-bit high definition
signals, the output can be attenuated by 66dB (very quiet) before bit truncation
Pure Class-A Analog Stage: The NAD M12 employs a pure Class-A buffer using the latest generation of Super OP Amps to provide low
impedance balanced (XLR) and single-ended (RCA) connections to power amplifiers
or active loudspeakers.
Modular Design Construction (MDC): Modular Design
Construction (MDC) helps to prevent obsolescence by providing a simple upgrade
path to add future features and functionality to the NAD Master Series M12
integrated amplifier. The following MDC modules are available -
- BluOs Module: By simply adding the optional BluOS MDC
sold separately), the M32 becomes part of the BluOS wireless multiroom music
ecosystem. The BluOS module connects to your network via a wireless (WiFi)
or wired (Ethernet) connection, and is controlled via Apple iPod
touch/iPhone/iPad, Android smartphone/tablet, Windows PC, or Mac computer.
BluOS supports streaming of internet radio, select online music services,
and Hi-Res audio files. The BluOS module also includes dual USB (type-A)
port for music file playback from USB mass storage class devices, like a
thumbdrive or digital portable audio player. In addition the BluOS module
offers built-in Bluetooth for wireless music streaming from a Bluetooth
source device, such as a smartphone, tablet, or computer.
- Balanced/Unbalanced & Phono MM/MC Module: The DD AP-1
sold separately) adds a balanced and unbalanced analog line-level input,
plus a MM/MC compatible phono input.
- 4K HDMI Module The MDC HDM-2 (745HDM2,
sold separately) adds HDMI capability with
three HDMI inputs and one HDMI output for video plass-through. Based on the
latest 6GHz HDMI chip, the MDC HDM-2 includes full support for UHD (4K)
video pass through to a video monitor, plus support for 24-bit/192kHz 2Ch
PCM (not compatible with Dolby Digital/DTS).
- 1080p HDMI Module: The DD HDMI-1 module (745DDHDM1,
sold separately) adds three HDMI inputs and one HDMI output for video pass
through. Full 3D Video support with video resolution up to 1080p/60.
Supports 2 channel PCM audio with 24-bit/192kHz resolution (not compatible
with Dolby Digital/DTS).
Note: These MDC modules are all sold separately (not
included). You can add up to two MDC modules.
Digital + Analog Connectivity
USB (Type-B) Port: The NAD M12 direct digital DAC is ready
for the world of computer audio with its rear-panel asynchronous USB (type-B)
input that can directly stream 24-bit/192kHz content from your Windows PC, Mac
computer, or other network-attached storage device (NAS). Your computer will
need to meet the following system requirements.
- Windows PC Users: Microsoft Windows XP Service Pack 2
or higher, Microsoft Windows 7.
- Mac Users: Minimum Mac OS X Snow Leopard (version 10.6)
and later versions.
Note: Download the "NAD
USB 2.0 Audio Driver" (from NAD's website) and install this driver to your Windows computer.
Mac OS X Snow Leopard (version 10.6) and later versions already include USB
Audio 2.0 drivers (no need to download NAD USB 2.0 Audio Driver).
Front- & Rear-Panel USB (Type-A) ports: The M12 features a front- and rear-panel USB
(type-A) port which allow you to connect a USB mass storage class (MSC) device,
such as a USB flash-drive or thumbdrive. The M12 will playback MP3, WMA, and
FLAC music files loaded on your compatible USB device. Your USB device must be
formatted in FAT 32.
Note: The USB ports are not
compatible with Apple iPod/iPhone/iPad or Android smartphones/tablets.
Digital Audio Inputs: The NAD M12 Direct Digital DAC
includes five digital audio inputs; two optical (Toslink), two coaxial (RCA), and
one AES/EBU (balanced XLR).
- Digital AES/EBU (XLR) Input: The NAD M12 is fitted with
a Digital AES/EBU (XLR) jack to connect high-end audio sources, such as SACD
and DVD-Audio players. For high-end sources with higher sampling rates like
176kHz and 192kHz, it is highly recommended that such sources be interfaced
with the AES/EBU (XLR) In connector.
- Digital Coaxial/Optical Inputs: The M12 also features
two rear-panel optical (toslink) digital outputs and two coaxial (RCA) digital outputs
to connect your digital audio components. Connect your CD, DVD, and Blu-ray
disc players. The Digital inputs support sampling rates of 32-192khz.
Note: If connecting to a television set's optical output,
please make sure that you are able to select PCM as the default optical out
audio format from your television's Audio menu. This DAC is not compatible
with multi-channel audio signals and will not work with televisions that do
not output PCM.
Balanced/Unbalanced Connectivity The NAD M12 offers balanced (XLR)/unbalanced (RCA) analog audio
inputs and outputs.
- Balanced XLR Inputs/Outputs: The M12 is fitted with a
pair of balanced XLR inputs to connect your high-end or professional audio
component. In addition, there is a pair of balanced XLR output to connect
your audiophile grade power amplifier.
- Unbalanced RCA Inputs/Outputs: There are two sets of
analog stereo unbalanced RCA inputs (including a Phono MM/MC input). There
is also one set of unbalanced analog stereo RCA outputs to connect to your
Dual Sub Outputs: The NAD M12 is equipped with dual mono-RCA
sub outputs to connect up to two powered subwoofers.
Remote Integration: The M12 offers 12V trigger, IR and
RS-232 connectivity for remote integration.
- 12V Trigger Input/Output: With this 3.5mm input triggered by a 12V
DC supply, the M12 can be switched On remotely from standby mode by compatible
devices; such as amplifiers, preamplifiers, receivers, etc. If the 12V DC supply
is cut off, the M12 will return to standby mode.
- IR Input: This 3.5mm input is connected to the output of an
IR (infrared) repeater (Xantech or similar) or the IR output of another
component to allow control of the M12 from a remote location.
- RS-232 Port: The RS-232 port allows connection to a
compatible PC or external whole-house control system from companies such as AMX
or Crestron. NAD is a certified partner of AMX and Crestron and fully supports
these external devices.
Touchscreen & Remote Control
Touchscreen Display: The NAD M12 features a front-panel display with
touchscreen control for easy-to-read text and simple control.
Remote Control: The supplied IR remote provides wireless
operation of the M12 and features controls for other NAD source devices.
Volume Control: The volume control adjusts the overall loudness of the signal
being fed to the loudspeakers. Volume control is characterized by perfect signal
tracking and channel balance. It gives a highly linear and low noise operation.
The volume control can set to "Fixed" or "Variable".
Tone Control: The M12 has the following Tone Control levels; Treble,
Bass and Balance. Bass and Treble controls only affect the low bass and high
treble leaving the critical midrange frequencies free of coloration. The Balance
control adjusts the relative levels of the left and right channels.
Auto Standby: The unit can be set go automatically go into standby
mode after approximately 30 minutes of inactivity.
