HD Radio Overview: HD Radio is digital FM and AM
broadcasting, allowing you to enjoy your same favorite FM and AM stations with
digital sound quality. FM stations offer near CD-quality sound and AM stations
sound like today's analog FM stations. Because the transmission is digital,
multi-path distortion (a common problem with analog radio, receiving signal
reflections slightly later than the direct signal) is eliminated. Stations broadcasting HD radio can also
pass along text information, such as artist name, song title, weather, traffic, etc.
Another benefit of FM HD radio is a station's ability to multicast, broadcast
multiple programs (up to seven) using their existing frequency. The display shows multicast
stations with the frequency followed by the multicast number, 107.1-1, 107.1-2,
107.1-3, etc. Unlike digital satellite radio, there is
no subscription needed to listen to HD radio.
Tuner: The Sangean HDT-1X has a Hybrid AM/FM
tuner; it receives analog and digital transmissions, plus RDS information. There
are several methods of tuning a station; the frequency and numeric buttons allow
you to input the frequency directly, the tuning buttons manually step up or down
the dial in 0.1 MHz or 10 kHz steps, the seek buttons search up or down the dial
for the next strong station, Analog mode allows you to only search analog AM/FM
stations and the HD seek buttons search only for HD Radio
broadcasts. The tuner's
frequency range coverage is as follows:
- FM and HD FM: 87.5-108.1 MH
- AM and HD AM: 520-1710 kHz
Presets: The tuner
features 40 presets for your favorite radio stations, including
primary and multicast HD stations and analog AM or FM stations. You can select
10 presets each from the FM1, FM2, AM1, and AM2 bands. Once you program
the presets, you can quickly tune them using the
numeric keys on the front of the tuner or the remote.
Stereo/Mono Mode: For stronger reception
of weak analog AM/FM stations you can choose Mono mode versus Stereo mode.
Split Audio Mode: Split Audio Mode
provides a digital signal out of the unit's left audio channel and provides an
analog signal out of the unit's right audio channel.
Analog and Digital Outputs: The HDT-1X
features a Left/Right stereo RCA analog audio output as well as a optical
digital audio output for connection between this tuner and your home A/V system.
Display: The unit's large LCD display clearly shows the station frequency
and radio band. You can adjust the displays contrast and brightness. Depending on the setting, it also displays:
- Station information:
frequency and preset number (plus text for RDS stations)
frequency and preset number plus other information the station can
transmit; call letters, nickname, etc
- Spectrum analyzer
- Signal Indicator
Built-In Clock: The HDT-1X has a
built-in clock that is displayed when the power is off and can be displayed
instead of station information when the tuner is on.
Remote Control: The HDT-1X comes supplied
with a full-function, credit card size IR wireless remote control.
