NAD C 427 Stereo AM/FM Tuner

Description

There’s nothing worse than bad reception when it comes to
listening to radio. The harsh crackling sound of static can ruin the most
sophisticated of systems, ultimately turning listeners away from the nearly
100-year-old medium. Thankfully, NAD has created a solution that will
adequately deliver quality reception. With 40 presets available to program your
favourite radio stations, the C 427 makes listening to the radio both smooth
and enjoyable. When scanning through different stations, the C 427’s Auto
Search will automatically stop at the strongest radio signal it encounters; the
FM Mute feature removes inter-station noise, allowing only the strongest and
clearest stations to come through. While keeping track of what stations you’ve
programmed can be tricky, the C 427 actually stores all preset information,
even when unplugged. With great reception and ease of use, the C 427 heightens
all the things that make radio great, resulting in a gratifying experience.

Broadcast Quality Reception

FM remains one of the most reliable and best sounding
mediums for hassle-free music listening. NAD’s C 427 builds on the strengths of
previous NAD tuners by offering a quality of reception that is as good as the
quality of today’s broadcasts. We have carried forward our highly sensitive RF
Front End for cleaner reception in fringe areas, plus noise is extremely low
across the audio spectrum. In line with NAD’s environmental policy, we have
completely redesigned the power supply for improved efficiency and ultra-low
power consumption during standby while still allowing all remote activation and
control interfaces. The rear panel IR Input, and RS-232 port, allow the C 427
to be easily integrated with sophisticated system controllers used in custom
installation. We also have one of the most intuitive user interfaces in the
market utilizing a 24-position rotary encoder knob to more quickly tune
stations or select preset stations. All functions are available via the
included IR Remote Control.

Loads of Presets

With 40 presets available you can store all your favourite
radio stations. These presets can be any combination of AM and FM stations. To
avoid having to scroll through 40 presets, the C 427 skips any that have not
been programmed (left empty), so you can quickly access all your favourite
stations.

Simply Convenient

Instead of littering the front panel with buttons and
features that are hardly ever used, the C 427 concentrates on convenience in
daily operation. The RDS limits itself to the RDS PS and RT function, both of
which enhance ease of operation. The RDS PS (Program Service) will
automatically indicate the name of the radio station on the display, e.g., “BBC
R1,” so you will always know exactly what station you are listening to. With
its four-line graphic display, you always see all the available information.
Preset information is stored in the C 427’s non-volatile memory, which means it
will remember all of its preset information even if the unit has been
unplugged.

Great Reception

Auto Search automatically stops at the next strong radio
signal it comes across and optimizes tuning. Weaker radio stations can be tuned
into manually. Stations that are quiet in Mono but noisy in Stereo can benefit
from the “Blend” feature that narrows stereo separation and lowers noise. FM
Mute eliminates inter-station tuning noise and only allows strong and clear
stations to emerge from the silent background. Although AM can never reach the
quality of any FM transmission, the C 427’s AM section retains excellent clarity
together with the lowest possible background noise.

Performance Driven

The NAD C 427 also offers features to get the maximum out of
the airwaves. The MOS-FET RF Front End design together with high quality
components and careful PCB layout guarantees excellent sensitivity with low
intermodulation distortion to provide a quiet and musically satisfying
performance.

Whether you are looking for excellent performance, ease of
use or the convenience of RDS, the C 427 offers all these with the value to
high performance ratio for which NAD is so renowned.
