C-350
NAD has always had a formidable reputation when it comes to quality, budget
amplifiers. The NAD 3020 in its various guises, and more recently the NAD
C320 and C340 all have received world-wide accolades for their outstanding
musical performance and superb value. As an encore NAD is proud to pre-
sent a new amplifier, further enhancing that reputation: the C350.
Features:
The C350 is fully remote controlled and comes supplied with the NAD C
Series system remote control. As the C350 has NAD Link the remote control
will also operate many other NAD products such as CD players, tuners, etc.
Flexibility is another NAD strong point. The C350 has 7 line inputs (including
2 tape in/outputs with dubbing facility) and the pre-amplifier section can be
separated from the power amplifier for easy upgrades or adding ancillary
equipment. Thus the C350 can be expanded to meet future system needs.
The C350 sports 2 pre-amp outputs: Many systems benefit from the use of
multiple power amplifiers for "Bi-Amping" (using separate power amplifiers
to drive the bass and treble section of a loudspeaker). With the second Pre-
out 2 facility an extra power amplifier, such as NAD's forthcoming C270
which has identical amplification factor (gain) as the C350's power amp sec-
tion- is easily connected.
For remote on/off switching of ancillary components in a system, such as
power amplifiers or active speakers, the C350 is equipped with a 12V-trigger
system. When switching the amplifier on, the 12V- trigger output is also acti-
vated which in turn can activate a 12V-trigger input and switch on the remote
devices. Besides the 12V-trigger, the C350 also has an AC switched outlet
(North American version only) so you can easily switch your entire system
on or off with the remote control or from the front panel.
It is fashionable to omit tone controls nowadays: However, provided that the
tone controls are properly designed, they can be really useful tools in making
improvements to the overall sound. The C350 tone controls only work at the
frequency extremes leaving the critical mid-band essentially unaltered. The tone
control circuits can be completely bypassed by using the tone defeat switch.
The C350 also incorporates NAD's acclaimed switchable "Soft Clipping" cir-
cuit, which significantly reduces the risk of damage to loudspeakers due to
prolonged high power operation.
Design: Impedance Sensing Circuit (ISC):
The C350 also benefits from NAD's proprietary Impedance Sensing Circuit
(ISC) topology, now well established and used throughout the NAD product
range notably in the highly reviewed models such as the C320 and C340. The
ISC topology allows the C350 to deliver maximum performance under virtu-
ally any circumstance, independent of the loudspeakers it is driving. The cir-
cuitry automatically senses the impedance characteristics of the loudspeaker
and will then adjust its power supply settings to best cope with that specific
load. This also gives it an unusual characteristic compared to traditional
amplifiers when measuring its continuous output power; the RMS output
power remains the same at 60 Watts with either an eight or four ohms load.
This is not unusual for NAD however.
NAD takes a stance to the mindless "brochure power" approach which doesn't
give a realistic indication of an amplifier's true capabilities. Instead, the ISC
topology is a practical approach to enable an amplifier to easily deal with
dynamics and difficult loads. More meaningful are the C350's dynamic capabil-
ities; up to 240 Watts into 2 ohms and up to 55 amps peak current capability!
Other design features include relay input switching (located right behind the
input sockets for short signal paths) and the large Toroidal transformer (less
mechanical hum and stray magnetic field). The generous power supply and
over-specified output devices further lead to low noise and low distortion for
the entire amplifier. Like all the other in- and output sockets, the Pre-
out/Main-in sockets are gold plated for long-term contact reliability. The
headphone socket will drive virtually any non-electrostatic headphone.
