Hybrid Digital Amplification: NAD has moved away from the
old-fashioned power-hungry linear power supplies and Class AB output stages that
waste nearly half of the energy consumed and produce heat rather than sound.
Instead, NAD has developed even better performing circuits based on switch mode
power supplies and Class D output stages. Once thought to be inferior to
traditional topologies, this new Hybrid Digital Amplifier design is very linear
over a wide bandwidth and provides consistent performance into all speaker
loads, providing a dramatic advancement over previous Class AB and Class D
- Customized Hypex UcD Output Stage: The NAD C 328
uses a customized version of the proven Hypex UcD output stage. This allows
for massive power with nearly immeasurable distortion and noise in the
audible range. Every detail of this design has been carefully crafted and
perfectly executed to deliver best performance possible.
- Efficient Power Supply: The power supply of the C 328 is able to
provide over 100 watts of audio output when needed. The C 328 can operate
with any AC mains voltage from 100V to 240V and provides pure DC power to
all of its various stages. This extremely efficient power supply also
provides near perfect regulation of voltage across a wide range of
conditions and provides a solid noise-free foundation for the amplifying
Full Disclosure Power (FDP): NAD uses Full Disclosure Power
(FDP), the most demanding criterion for performance measurement. FDP specifies
distortion under the most extreme conditions of low impedance loads and
frequency extremes, rather than the simple and easy 1kHz @ 8 ohms test quoted by
many of other manufactures. NAD uses this stricter performance criterion because
it more closely matches the demands of real music and real loudspeakers.
Maintaining specified distortion at 4/8Ω and at 20-20kHz is a much more
difficult achievement. The benefit of NAD's Full Disclosure Power is the total
elimination of audible distortion at any listening level. This provides pinpoint
imaging and realism with music and movies alike.
- Continuous Power: 40 watts x 2-channel (@ 20-20kHz,
into 4Ω or 8Ω, at 0.03% THD, with both channels driven)
- IHF Dynamic Power: 90 watts 2-channel into 8Ω or
166 watts x 2-channel into 4Ω
Bass EQ: The Bass EQ function boosts overall bass response by at least
Digital Inputs: The NAD C 328 is equipped with two optical
(toslink) digital inputs and two coaxial (RCA) digital inputs. These digital
inputs will support 2ch PCM audio up to 24-bit/192kHz (not compatible with Dolby
Analog Inputs: The NAD C 328's stereo RCA inputs (2 Line/1 Phono) can
accommodate all kinds of analog source components by offering ideal input
impedance characteristics with linear ultra-low-noise buffer amplifiers to
prevent any sonic degradation caused by inappropriate loading of the source
MM Phono Stage w/ RIAA Equalization: The NAD C 328 hybrid
digital integrated amplifier includes an MM Phono stage with precisely accurate
RIAA equalization, high overload margins, extremely low noise, and an innovative
circuit to suppress infrasonic noise that is present on all LPs - all without
affecting bass response.
Bluetooth Audio Streaming: Built-in Bluetooth allows you to
wirelessly stream your music library, music apps, podcasts, audiobooks, and
other audio content on your Bluetooth source device (such as your smartphone,
tablet, or laptop) to the NAD C 328. You can control basic playback functions
(such as Play/Pause, Previous/Next Track, and Volume Up/Down) from the included
IR remote. You can only pair and connect one device at a time.
Note: The included antenna must be connected to the rear-panel of the
integrated amp in order for Bluetooth to work.
Discrete Headphone Amplifier: The NAD C 328 incorporates a
discrete headphone amplifier with low output impedance and very high output
voltage capability, enough to drive even high impedance studio monitor
headphones. Connecting a set of headphone to unit's front-panel 1/4" jack will
mute the speaker outputs. Volume, tone, and balance controls are all operable
during headphone listening.
Binding Post Speaker Outputs: The speaker output terminals
consist of four binding posts to connect a single pair of loudspeakers. The amplifier supports 4Ω
to 8Ω speakers. These
binding post terminals will accept bare wire (up to 10AWG), pin-connectors,
spade-lugs, and banana plugs (single only). You'll need to remove the plastic
inserts within the binding-post terminals to connect banana plugs.
Sub Out: The NAD C C328 is equipped with a mono-RCA subwoofer output
for connection of a powered sub. The subwoofer out features a fixed low-pass
crossover set a 100Hz.
IR Remote: The included IR remote provides wireless operation of the C
328 hybrid digital integrated amplifier and basic playback control of your
connected Bluetooth source device.
RS-232 Port: The RS-232 port allows connection to a
compatible PC or external whole-house control system. NAD is a certified partner
of Control4, Crestron, RTI, URC, AMX, Savant, & Elan.
Auto Sense & Auto Standby: The Auto Sense feature enables
the C 328 to wake up from standby mode when triggered by an active analog or
digital source input with an audio signal. The C 328 can also be setup to
automatically go into standby mode if there is no user interface interaction and
no active source input for 20 minutes.
