NAD M12 - Masters Series Preamplifier/DAC - BluOS Ready + MDC
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 begins.
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.
Note: MDC modules are all sold separately (not included).
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.
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 iOS 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 stereo amplifier.
Dual Sub Outputs: The NAD M12 is equipped with dual mono-RCA sub outputs to connect up to two powered subwoofers.
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 characterised 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.
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.
Auto Standby: The unit can be set go automatically go into standby mode after approximately 30 minutes of inactivity.
