Features
NAD PowerDrive Circuit: The C 375DAC uses NAD's proprietary
PowerDrive amplifier technology that provides high dynamic power and low
impedance drive capability. By adding a second high-voltage rail to the amp's
well regulated high-current power supply, the amplifier can nearly double its
continuous power on a short term dynamic power basis. This uniquely efficient
power supply topology provides the real world benefits of high dynamic power
that remains uncompromised by low impedance speakers.
FDP Specifications: 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 ohms and at 20Hz to 20kHz is a much more
difficult achievement. The NAD C 375DAC is rated at 150 watts x 2 channel (@
20-20kHz, in 4/8-ohm, with 0.007% THD).
Bridgeable: The C 375DAC can be bridged to a single channel,
more than doubling the power output. When bridged, the minimum recommended
speaker impedance is 8Ω. In Bridged mode, the C 375DAC will produce
approximately 330 watts.
Soft Clipping: NAD's Soft Clipping circuit gently limits the
output of the C 375DAC to minimize audible distortion when the amplifier is
over-driven. While Soft Clipping can be left on at all times to reduce the
likelihood of audible distortion from excessive volume settings, you can also
turn the circuit off for critical listening if you prefer.
Digital-to-Analog Converter (DAC): The C 375DAC stereo
integrated amplifier is fitted with NAD's MDC DAC USB Digital-to-Analog
Converter which lets you listen to music stored on or streamed to your computer
through your hifi-system without noise or distortion. The C 375DAC uses an
'asynchronous USB' technique and a high precision clock, so your 24-bit/96kHz
quality computer music flows smoothly without 'jitter' or harsh distortion.
Modular Design Construction (MDC): Modular Design
Construction (MDC) makes future upgrades possible with interchangeable,
upgradeable modules.
Controls
Remote Control: The included IR remote control handles the
key functions of the C 375DAC. The IR remote can also be used to directly
command other NAD products that respond to applicable common remote control
codes. This includes other NAD Stereo Receiver, Integrated Amplifier, and
Preamplifier models. It has additional controls to remotely operate NAD CD
Players, AM/FM Tuners, and dedicated AM/FM/DB Tuners. It will operate up to a
distance of 23'. The remote requires two "AA" alkaline batteries (included).
Balance: The Balance control adjusts the relative levels of
the left and right speakers. The Balance control does not affect recordings made
using the Tape output terminals, but will affect the signal going to the Pre-amp
output terminals (Pre Out 1 and Pre Out 2).
Tone Controls: The C 375DAC stereo integrated amplifier
features independent Bass (100Hz) & Treble (10kHz) controls to adjust the tonal
balanced of your system. The Tone control does not affect recordings made using
the Tape output terminals, but will affect the signal going to the Pre-amp
output terminals (Pre Out 1 and Pre Out 2).
Note: The Tone control circuits can be bypassed.
Connections
USB (Type-B) Port: The C 375DAC stereo integrated amplifier
features a rear-panel USB (type-B) port to connect to your computer, so you can
listen to music stored on or streamed to your computer (Windows or Mac). The USB
input supports audio sampling rates of 32kHz to 96kHz.
Note: The rear-panel DAC Module switch must be set to
USB.
Optical Digital Input: The stereo integrated amplifier also
features a rear-panel optical (toslink) digital input for connecting of your CD,
SACD, DVD, or Blu-ray player. The optical digital input supports audio sampling
rates of 32kHz to 192kHz.
Note: The rear-panel DAC Module switch must be set to
Optical.
Front-Panel Stereo Minijack: The NAD C 375DAC is equipped
with a front-panel stereo minijack (3.5mm) to temporarily connect your portable
digital audio player.
Analog Inputs: The NAD C 375DAC stereo integrated amplifier
is fitted with 5 rear-panel analog stereo audio inputs (RCA). These inputs are
labeled 'MP', 'CD', 'Tuner', 'Disc', and 'AUX'.
Tape Monitor Inputs/Outputs: The NAD C 375DAC is equipped
with two stereo Tape Monitor outputs (labeled 'Tape Monitor' and 'Tape 2') for
recording purposes.
A-B Speaker Terminals: The NAD C 375DAC is fitted with A & B
speaker outputs. You can choose to play back only the A speakers, only the B
speakers, or both A-B speakers. You can also use both A-B speaker terminals to
Bi-amp your speakers. The speaker terminals are binding-posts and will
accept single banana plugs, pin connectors, or bare wire (16-12 AWG).
Note: The stereo integrated amp will support one pair of
4 to 8-ohm speakers or two pair of 8-ohm speakers.
Preamp Outputs: The C 375DAC features dual stereo pre-amp
outputs (labeled 'Pre Out1' and 'Pre-Out 2') to connect the unit to an external
power amplifier or power subwoofer.
Main Input: This is a stereo RCA connection which allows the
connection of an external preamplifier or processor.
Headphone Output: The C 375DAC is fitted with a front-panel
1/4" headphone jack for connecting a set of headphones (sold separately). The
headphone jack will work in parallel with the selected speakers (A and/or B). To
listen to only your headphones, de-select Speakers A-B. The volume, tone, and
balance controls are operative for headphone listening.
IR Input/Output: There is an IR input (3.5mm), used to
control this unit using an optional infrared repeater or the IR output of
another component. There is also an IR output (3.5mm) used to control another
compatible component.
+12V Trigger Output: The +12V trigger output (3.5mm) lets
you turn on/off another device along with the C 375DAC.
RS-232 Port: The rear-panel 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.
Switched AC Outlet: This convenient outlet can supply
switched AC power to another component or accessory. The total draw off all
devices connected to this outlet must not exceed 120 watts.
AC Power Cord: The C 375DAC comes supplied with a detachable
68" AC power cord.
