How HD Radio works
HD Radio produces a smooth, natural response and room-filling sound that
belies its compact size. HD Radio stations can broadcast data (artist and song
information, weather, traffic, and more) and multiple channels at their same,
familiar position on the radio dial.
1. The digital signal is compressed using HD Radio compression
technology.
2. Stations bundle both analog and digital audio signals, and the
combined analog and digital signals are transmitted.The signal will be
compatible with both HD Radio receivers and analog radios.
HD Radio receivers are designed to reduce static, hiss, pops, and fades by sorting
through reflected signals and multi-path distortion. Multi-path distorition is the
most common form of interference, and occurs when part of a signal bounces
off an object and arrives at the receiver at a different time than the main signal.

Quick Start
Connecting Your Radio
To avoid interference, keep the power supply away from the radio while in use.
FM ANT
AUX IN
Connect FM antenna. Use the“T”
shaped antenna in
more remote areas.
Connect auxiliary devices with
headphone output. To listen to
auxiliary devices, select AUX mode.
AM Antenna
DC IN
Press down the two
spring terminals,
connect the AM
antenna wires, and
position the antenna
for the best reception.
Plug the power supply into the
DC IN port, plug the AC cord into
the power supply, and then plug
the AC plug into the wall outlet.
Cable Radio Signals
The Radio’s FM antenna connector is a standard F-connector and will accept
cable FM feeds from most cable systems that provide FM programming.To
connect your radio to the FM signal from some cable TV providers, contact your
cable TV provider for assistance.
The installation must include a splitter that filters the signal to prevent any
re-emission of the RF spectrum through the radio, so only the FM band, not
the cable TV signal, is transmitted to the Radio. HD signals are not currently
rebroadcast via cable providers.

and FM2) for a total of 24.
Beyond the Basics
Multicast Channels
In addition to digital sound quality, HD Radio broadcasters can offer multiple
programming channels simultaneously using their existing frequency on the
radio dial. These additional channels can offer expanded news, talk, and music
formats.
When your radio tunes in the HD channel, if a number appears on the right
side of the station frequency (for example: 89.3-1), this indicates the existence
of multicast services. Use the TUNE - / + to select a multicast channel for the
frequency.
System Delay
Digital systems inherently produce an audio delay.To overcome this delay,
HD Radio uses a station’s analog signal to enable fast tuning of an AM or
FM station. After approximately 5 seconds, the audio from the analog signal
changes to digital HD Radio. If the radio station has implemented the HD Radio
broadcast correctly, the blend is smooth. However, if the station has not, you will
experience a skip in content of up to 5 seconds for a -2 or higher channel.
This is not an issue with your HD Radio.This is an HD Radio broadcaster’s
implementation issue, which should be corrected by the station over time.
Today’s analog is only present on the main channel. Should you tune directly to
a station’s multicast channel, the HD Radio Tabletop will delay playing audio or
content for up to 5 seconds.This is normal operation.

FAQ
Why does my audio quality change after a few seconds on some HD Radio
stations and on some other stations skip when I first tune in?
HD Radio stations blend analog signals to digital HD Radio.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.This is an HD
Radio broadcaster’s implementation issue, which the station should correct over
time.
What can I do if I my audio is unclear or I don’t hear any audio?
If your radio audio is unclear or you don’t hear any audio, you may be
experiencing one of the following conditions:
•
•
Is the radio muted? If so, unmute the radio or turn up the volume.
Is the radio in AUX mode? If so, your auxiliary device may not be sending
audio signals or may not be correctly connected.
•
•
•
Is anything plugged into the headphone jack? If so, unplug it.
Check all connections, including power and antenna.
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: If you are using an amplified antenna with adjustable gain, turn down
the gain all the way and adjust slowly upward.
