RDS: The RDS limits itself to the RDS PS (Program Service) and RT
(Radio Text) function, both of which enhance ease of operation. The RDS PS will
automatically indicate the name of the radio station you are listening to in the
display. At the touch of a button, RDS RT will display additional information
broadcast by the radio station, such as the presenter, the music playing, etc.
Fine Tuning: With each brief rotation of the C 426's
front-panel rotary dial, the tuner will take 0.05 MHz steps for the FM band and
10 kHz for the AM band. You can also use the remote's numeric keypad to directly
enter a station's identification number. Auto Search automatically stops at the next strong radio
signal 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 improves noise. FM Mute
eliminates inter-station tuning noise and only allows strong and clear stations
to emerge from the silent background.
30 Presets (w/ Naming): With 30 presets available, you can store all
your favorite radio stations in any combination of AM and FM stations. To avoid
having to scroll through 30 presets, the un-programmed (empty) ones are skipped
to give you quick access to all your stations. For AM and non-RDS stations the C
426 FM/AM Tuner allows you to name each preset individually with up to eight
characters. Once you have named your presets you don't need to remember which
frequency goes with what radio station, as the name is indicated in the display
every time the preset is recalled. All the preset information is stored in the C
426's non-volatile memory, which means it will remember all of its preset
information even if the unit has been unplugged for a prolonged period.
Connections: The NAD C 426 tuner features a threaded F-type connector
to connect the included FM wire antenna, and two spring-clip terminals to
connect the included AM loop antenna (you can upgrade antennas). The NAD C
426 is fitted with a set of stereo RCA outputs and comes with a 38" audio cable
to connect the tuner to your AV receiver. The rear panel IR input (3.5mm), +12V Trigger
input (3.5mm), and RS-232 port allow the C 426 to be easily integrated with
sophisticated system controllers used in custom installation. The tuner also
comes with a detachable 6.5' AC power cord.
Simple Operation: Instead of littering the front panel with
seldom-used buttons and features, the C 426 concentrates on the essentials. It
features an intuitive user interface with a 24-position rotary encoder knob to
quickly tune stations or select preset stations. The included IR remote provides
wireless operation of the tuner.
VFD: The C 426 features a Vacuum Fluorescent Display which provides
visual information on the settings, conditions, status, and other information
relevant to the currently tuned station. The display offer three brightness
Sleep Mode: The tuner's Sleep Mode timer will switch the C 426 to
"standby mode" automatically after a preset number of minutes (30, 60, 90, or
