Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

AM/FM/SW Radio: The Grundig S450DLX portable radio features an AM, FM, and Shortwave tuner. Although the readout is digital, the tuner is analog, allowing fine frequency tuning. The unit offers 3 frequency tuning steps (fast/slow/stop). The frequency lock helps minimize signal drifting when listening to AM, FM, or SW stations. You can store up to 50 station presets; 10 for each band (FM, AM, SW 1/2/3).

• AM: AM stations in North America range from 520 to 1710kHz  (10kHz steps) and from 522 to 1620kHz (9kHz steps) in other parts of the world. The AM antenna is built into the radio (there are also spring-clip connectors for adding an external AM antenna). There is an AM RF gain knob which compensates for distortion between strong and weaker stations. In addition, you can select a Wide or Narrow bandwidth setting to reduce interference from adjacent frequencies.
• FM: The FM frequency range is from 87 to 108MHz. The unit features a telescopic antenna (there is also a coaxial connector for upgrading the FM antenna). You can set the FM band to Mono (when listening through built-in speaker) or Stereo (when listening through headphones). If the FM station you're listening to is too strong that it sound distorted, switch to Local mode. Otherwise, leave it on DX mode, which stands for maximum distance.
• SW: Shortwave enables listening to broadcasts over vast distances including other countries and continents. Shortwave has continuous frequency range from 1711 to 29999kHz. The Shortwave tuner uses the same telescopic antenna as the FM tuner.

LCD Backlight Display: The S450DLX features a large LCD backlight display with frequency, clock, battery level indicator, and signal strength indicator.

Full-Range Sound: The S450DLX uses a high performance MOSFET amplifier to power its single full-range speaker. The unit also offers bass & treble control.

Auxiliary Input: There is a minijack (3.5mm) auxiliary input for connecting an external audio source (such as your MP3 player) to the Grundig S450DLX.

Line Output: There is also a minijack (3.5mm) line output which allows you to feed the audio signal of the S450DLX to another component, such as your home stereo system.

Headphone Jack: A 3.5mm (1/8") headphone jack allows you to connect a set of earphones for private listening. The unit's speaker will mute when headphones are connected.

Alarm Clock: The Grundig S450DLX features a 12/24hr digital clock with dual wakeup alarms, snooze function, and sleep timer (1/5/10/15/30/45/60/90 min).

Carry Strap: The AM/FM/Shortwave field radio includes a carrying strap to make it easy to take with you to the office, outside, or on vacation.

Dual Power Source: The Grundig S450DLX can operate off of 6 "D" batteries (not included) or AC power (using the included AC power adapter). In the event of an AC power failure, the radio stays on and switches to battery power (if batteries are installed).
