Direct Digital Amplification: The NAD Master Series M32
employs an innovative DirectDigital Feedback Amplifier built under license from
Cambridge Silicon Radio (CSR). This is a true digital
amp (not just Class D) that is computer controlled and amplifies entirely in the
digital domain, converting to analog at the speaker terminals.
DirectDigital amplification combines all pre-amplification and power
amplification functions into a single amplifying stage with incredible fast and
accurate digital correction. Advanced
software-controlled algorithms result in the shortest signal path from source to
speaker to produce virtually no distortion and a high damping factor.
This technology is among the fastest and most accurate amplification and error
- Continuous Power:
- 8Ω: 180 watts @
20Hz-20kHz with 0.03% THD
- 4Ω: 180 watts @
20Hz-20kHz with 0.03% THD
- Dynamic Power:
- 8Ω: 220 watts
- 4Ω: 360 watts
- 2Ω: 400 watts
DirectDigital amplification combines all preamp and power amp functions of the
Master Series M32 into a single amplifying stage controlled by software. Highly
advanced mathematics determines all control functions including volume and
filters. This produces a dramatic reduction in noise and distortion, and brings
you much closer to both the music and the performers. Traditional volume
controls that change the gain in an active analog circuit cannot approach the
transparency of the M32. It also allows accurate tone controls that only change
tone, without adding phase shift or distortion.
Rugged Construction: The NAD Master Series M32 integrated amplifier's all-alloy casework is elegant
and rugged. Rigid panels with magnetic iso-point
feet provide a solid foundation for the multi-layer circuit boards and intricate
Asynchronous USB-B Port: The NAD M32 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).
Digital Inputs: The NAD M32 includes five digital audio
inputs; two optical (Toslink), two coaxial (RCA), and one AES/EBU (balanced XLR).
- Digital AES/EBU (XLR) Input: The NAD M32 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 M32 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
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.
Analog Inputs (including Phono): The NAD M32 is
outfitted with two analog stereo RCA line inputs and a MM Phono input. An
accurate RIAA equalization, a clever phase cancelling infrasonic filter, and a
huge overload margin combine to bring out the best in your vinyl collection.
Digital Output: The optical (toslink) output & coaxial (RCA) digital
output can be used to connect the M32 integrated amplifier to a corresponding
digital audio input of an AV receiver, computer, or other digital processor.
Pre-Out: The integrated amplifier's stereo analog RCA output can be
used as a full-range pre-out, making it possible for the M32 to be used as a
full-range preamplifier to an external power amplifier. The stereo analog RCA
output can also be used as a low frequency output to connect one or two powered
subwoofers, so only low frequency information is sent to the connected
powered subs. When used as a sub output, you have access to a variable low-pass
crossover (40-200Hz) and trim level (-12 to 0dB).
Two Sets of Speaker Terminals For Bi-Wiring: The M32 has two sets of
speaker terminals which are identical in function and are wired in parallel.
They allow for bi-wiring a single pair of speakers. Each speaker terminal
consists of a binding post that will accept up to 10AWG wire, pin-connectors,
and banana plugs (single only).
Discrete Headphone Amplifier: The NAD Master Series M32
is equipped with a fully discrete headphone amplifier which is able to drive
even planar and high impedance studio monitor headphones. With high voltage and
low output impedance, your headphones will sound their best. Volume, tone, and
balance controls are available during headphone listening. When a set of
headphones is plugged into the front-panel 1/4" headphone jack, the integrated
amplifier's speaker outputs will be muted.
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 M32
integrated amplifier. The following MDC modules are available -
- BluOs Module: By simply adding the optional
BluOS MDC Module(745MDBLUOS,
sold separately), the M32 becomes part of the BluOS wireless
multiroom music ecosystem. The BluOS module connects to your
