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 amplifier designs.
- Customized Hypex UcD Output Stage: The C 388 uses a
customized version of the proven Hypex UcD output stage operating in a fully
balanced bridge configuration. This allows for massive power with nearly
un-measurable distortion and noise in the audible range. Every detail of
this design has been carefully planned and perfectly executed to deliver
every last drop of performance.
- Sophisticated Power Supply: The C 388's power supply
is capable of 400 watts continuously and over 1,000 watts instantaneously to
allow for short-term musical transients. It can operate with any AC mains
voltage from 100 to 240 volts and provides pure DC power to all the various
stages of the C 388. This highly efficient supply also provides near perfect
regulation of voltage across a wide range of conditions and provides a solid
noise-free foundation for the amplifying stages.
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: 150 watts x 2-channel (@ 20-20kHz, into 4Ω or
8Ω, at 0.009% THD, with both channels driven)
- IHF Dynamic Power: 400W into 2Ω / 350W into 4Ω / 250W into 8Ω
Binding Post Speaker Outputs: The amplifier features A & B
speaker terminals to power two pair of loudspeakers. The speaker terminals
consist of eight binding posts that will accept single banana plugs (single
only), pin connectors, spade lugs, and bare wire (up to 10AWG). The amplifier
supports 4Ω speakers when only one pair is connected, however, when two pair of
speakers are connected a minimum impedance of 8Ω is recommended.
Discrete Headphone Amplifier: The NAD C 388 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
Line Outputs: The C 388 features a low impedance line-level
stereo output that
can connect to another other amplifier or powered subwoofer to extend the hybrid
digital DAC amplifier's versatility.
Tone Control: The NAD C 388 hybrid digital DAC amplifier
lets you adjust Bass (60Hz) & Treble (20kHz) from -7 to +7dB, as well as Balance
between the left & right speakers (L10 to R10).
Filters: Filters provide easy bi-amplification or subwoofer
integration by adding the required filters to redirect bass frequencies to the
subwoofer. Select High Pass or Full Range. When High Pass is selected, low pass
audio signals within the 40Hz to 200Hz are sent to the C 388's subwoofer preout
and high pass audio signals are sent to the C 388's amplifier section and
speaker outputs. Select Full-Range to deliver audio signals with the whole
frequency spectrum to the C 388's amplifier section and speaker outputs.

Bluetooth Music Streaming: You can wirelessly pair and
connect instantly to the C 388 with Bluetooth (4.0), allowing you to stream stored
music and music apps wirelessly from your Bluetooth-enabled source device; like
your smartphone, tablet, laptop or desktop computer. The high performance
Bluetooth aptX codec is fully supported for true CD-quality sound from aptX-compatible
Bluetooth devices (like Android OS 4.0+ smartphones & tablets). There is no
control or song/artist info display from the C 388.
Note: If the optional MDC BluOS module (sold separately) is installed, Bluetooth as Source
will be defeated or not selectable. Use the Bluetooth option included in the MDC
Digital Inputs: The NAD C 388 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 388'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 device.
MM Phono Stage w/ RIAA Equalization: The NAD C 388 hybrid digital DAC
amplifier includes an MM Phono stage with precisely accurate RIAA equalization,
