HD Radio Technology & Multicasting

The single largest technological advancement in radio in more than 45 years, HD Radio technology is the new standard
for digital AM and FM radio in the US and around the world. HD Radio technology transforms your radio listening
experience in exciting new ways, offering you the quality, choice and interactive data services that are fast becoming
a new information and entertainment standard.
Multicasting, which is the ability to broadcast multiple program streams over a single FM frequency (97.7-2, 97.7-3,
etc.), greatly increases the amount and diversity of content you can access. HD Radio technology offers:

St

atic-free, crystal-clear reception
CD-quality sound on FM Digital; FM-stereo quality sound on AM
Stations stay in their well-known, traditional place on the radio dial
A variety of “data services” ranging from text-based information (artist name, song title, weather alerts, school

closings and more) to live traffic reports, all of which would scroll across your receiver display.

Setting Up Your HDX3

1. Connect The FM Antenna

To attach either of the provided FM antennas, connect it to the 75 ohm port and position for best reception. For optimal FM reception, use the
T-shaped dipole. Position its “arms” laterally or vertically for best reception of your favorite stations. The black wire antenna may be adequate for
receiving strong stations in urban areas, while the dipole will provide better reception of weak stations from more rural locations.

Note For Cable Radio

The HDX3 can accept cable FM programming. Contact your cable TV provider for assistance connecting your radio to a cable FM feed. The cable
installation must be able to filter re-emission of the RF spectrum so that only the FM band, and not the cable TV signal, is transmitted to the radio.

2.

Connect The AM Antenna

Connect the AM antenna wires, matching the color to the AM antenna terminals and position the antenna for best reception.

3.

Connect The Speakers

Connect the speaker wires to the + / - terminals on the speakers and on the HDX3 console (RED to RED and BLACK to BLACK). For best stereo
reproduction, each speaker should be approximately the same distance away from the primary listening position, and this distance should be
approximately equal to the separation between the two speakers. Finally, for best bass performance place the speakers at least 1” (25 mm) from a
back wall.

Note

To avoid blocking the cooling vents on the sides of the HDX3 console, place the speakers at least 1” away from the console sides.

4. Connect The Power Supply

Plug the power-supply cord into a wall outlet.

5. Connect
To connect the HDX3 to another audio device, connect a stereo cable (not supplied) to the LINE
OUT (VAR) port. The HDX3 volume controls also control the volume for playback, so this full-range

output can be used with a subwoofer or a full-range speaker system.

6. Connect

Turn down the volume level on both the device you are connecting and the HDX3, and plug the
device into the AUX port on the front of the HDX3. Start with the volume in the 12 o’clock position.

Connecting Headphones

Connect the headphones into the stereo minijack on the front of the console.

Note

The headphone jack can be used as a stereo output jack.
When you connect headphones, the speakers are muted.

Tuning A Station

1. Press the Volume/Mode knob on the HDX3 console or MODE on the
remote control to select either an AM or FM mode.

2. Use the tuner buttons on the HDX3 console or on the remote control

to select a station.

3. To search for a station, press and hold the tuner buttons. When the
HDX3 recognizes an HD Radio channel, the HD Radio logo appears.

HD Radio Multicast Channels (FM Only)

In addition to digital-quality sound, some HD Radio broadcasters offer
multiple programs simultaneously using multicast channels on their
existing frequency.

If the station offers multicast programming, “-1” appears next to the
station frequency. Use the tuner buttons to select multicast channels.
Tuning up the frequency band will take you to that radio station’s next
subchannel, which would have a “-2” after its frequency.

Audio Delay In HD Radio Systems

Digital systems inherently produce an audio delay. The HDX3 uses
a station’s analog signal to tune the station. After approximately 5
seconds, the analog audio blends to digital. The blend is typically
smooth, but if the station has not implemented their HD Radio
broadcast correctly, you may experience a skip. This is not a problem
with your radio. It is a broadcast implementation issue, which the
station should correct over time.

Only the main channel contains an analog signal. If you tune directly to
a station’s multicast channel, the audio will delay for approximately 5
seconds. This is normal operation.

Note

HD Radio broadcasts in the AM band may terminate at night due to
FCC regulations.

FAQ
Why does my audio quality change after a few seconds on some
HD Radio stations?

HD Radio stations blend analog signals to digital HD Radio signals.
The blend is typically smooth, but in some cases, the audio quality
can take a few seconds to reach enhanced digital levels. This is not
an issue with your HD Radio receiver.

What can I do if I my audio is not clear or I don’t hear any audio?

If your radio audio isn’t clear or you don’t hear any audio, you may be
experiencing one of the following conditions:

Check all connections, including power and antenna.

¤

Is anything plugged into the headphone jack? If so, unplug it.
Is the signal too weak? If so, tune to a stronger station or reposition

¤

your radio and/or antenna.

¤

If you are using an antenna other than the one supplied, make sure

the antenna supports FM reception. If the antenna uses an FM trap,
make sure the FM trap is off.

Note
