HD Radio Station Notes

ART7

1.When a radio station is broadcasting an HD Radio signal, the HD icon ( ) will blink to indi- cate ART7 is acquiring the HD Radio signal. When the signal is acquired, the HD icon will stop blinking and appear on the display.

Multicasting Note: Multicasting is a feature of HD Radio technology that enables stations to broadcast multiple streams of data on sub-channels of their main frequency. The multicast stations may contain other music formats, local traffic, weather and sports. These multicast stations are found "between" the stations already on the frequency band.

(Note: Multicast Radio Stations are accessed in the same manner as you would any station frequency using the Tune or Seek functions.)

2.HD Radio Multicast (FM Only): Besides offering static free and clear radio signals, HD Radio technology also allows FM radio stations to multicast. This allows radio stations to offer more than one programming channel or station (multicast) at a time using their existing frequency on the radio dial.

Multicast Example: For example: If the main radio station is 103.5, then that same radio sta- tion may have station multicasts of 103.5-1, 103.5-2. The suffix 2, 3, 4, 5, 6, 7 represents the stations multicast sub-channel. Position -1 is always the main station's program.

3.Not all HD Radio stations will broadcast multicast programs. Those that are multicasting will typically have 1 to 2 multicast programs at this time, with more being added all the time.

4.Unavailable Digital Signal/Loss of Digital Signal: If the ART7 incurs a loss of digital HD Radio signal, the radio mode will automatically change to analog radio mode. If a station's multicast service is interrupted while playing, the ART7 will switch to the main station program. If a multicast station saved to a preset is chosen when the multicast station is not available or loses signal, the ART7 will switch to the radio station's main broadcast station.

5.HD Radio Delay: To overcome the delay that digital systems inherently produce, HD Radio technology first uses a station's analog signal to quickly tune to an AM or FM station. After approximately five seconds, the audio will then blend from the station's analog to digital HD Radio signal. Normally, this blending from analog to digital signals is very smooth. When the changeover is smooth, the radio station has implemented the HD Radio broadcast correctly. However, if the station has not, you may experience a skip in program content of several seconds. This is not a problem with your ART7. This is an HD Radio broadcaster's issue. This will be corrected by the station over time. Today's analog programming is only present on the main channel. If you select a preset HD channel and tune directly to an HD Radio station's digital multicast channel, the ART7 will take approximately five seconds to begin playing. This is normal operation.
