AM/FM Interval (span)
The International Telecommunication Union (ITU) has established that member countries should maintain either a 10
kHz or a 9 kHz interval between broadcasting frequencies
of any AM station. The illustration shows the 9 kHz interval
zones (regions 1 and 3), and the 10 kHz interval zone (region
2).
This product is not equipped with a span selector. However,
it will be adjusted to 9 kHz AM interval (50 kHz FM interval)
when shipped from the factory.
Before using the unit, be sure to set it for the AM tuning
interval (span) used in your area.
To check the tuning span currently selected:
1
Set the ON/STAND-BY button on the main unit to ON.
2
Press the TUNER (BAND) button until "FM" or "AM" appears in the display.
3
Press the TUNER (BAND) button to select the AM band.
● If "AM 531 kHz" is displayed, it means that the radio has
been adjusted for a 9 kHz span. If "AM 530 kHz" is displayed, it means that the radio has been adjusted for a
10 kHz span.

ENTER
To change from a 9 kHz AM (50 kHz FM) interval to a
10 kHz AM (100 kHz FM) interval:
1
Press the ON/STAND-BY button on the remote control
to enter the stand-by mode.
2
Hold down the TUNER (BAND) button and the ENTER
button for at least 4 seconds. Release the buttons when
"AM SP 10 kHz" and "FM SP 100 kHz" are displayed
alternately.
To return to a 9 kHz AM (50 kHz FM) interval:
1
Press the ON/STAND-BY button on the remote control
to enter the stand-by mode.
2
Hold down the TUNER (BAND) button and the ENTER
button for at least 4 seconds. Release the buttons when
"AM SP 9 kHz" and "FM SP 50 kHz" are displayed alternately.
Caution:
● When the unit is left for a few hours after the span has
been switched and AC power lead disconnected, it will
be automatically returned to a 9 kHz span. If this happens, set the span again.
● When the span is switched, any stations that are
memorised will be cancelled.

EXPLANATION OF AUTOMATIC SOUND VALUE CORRECTION CONTROL
1. Outline
The recent trend is toward rise of SOUND level in the world, for example rock, dancing music, etc. In case of continuous high
level playback and VOL (Volume) are controlled (lowered) automatically after a lapse so as to get the easy-to-listen sound level.
The ALC (Automatic Level Control) of the HT-DD5000 begins to operate immediately after the power is turned on.
2. Explanation of operation
The SOUND operation is explained below.
ALC operation
1
The ALC (Automatic Level Control) will begin operation immediately after the power switch is turned on.
2
If the sound exceeds level X , the ALC will instantaneously cut the volume back to level X , and it will also respond to
monophonic signals.
3
Since this control only effects the VOL level, it does not otherwise change the quality of the sound.

DOLBY DIGITAL
DVD
When you connect this unit to a DVD player which is playing
a disc with the trademark, you can enjoy realistic,
powerful sound by playing back the recorded signal through
6 speakers with the sound coming from the front left, front
right, centre, surround left, surround right and sub woofer
speakers.
To listen to a disc using the Dolby Digital mode:
1 Connect a DVD player.
2 Press the DVD button.
● The current DVD input channel will be displayed. If the
DVD button is pressed whilst the current DVD channel is
DVD
displayed, the input channel (ANALOG, COAXIAL, OPTICAL) can be changed.
3 Start the DVD player.
Note:
● When the Dolby Digital surround mode is being used, the
equalizer will be set to FLAT.
Type of Dolby digital signal
There are different types of Dolby digital signals. When you select COAXIAL or OPTICAL for the DVD input channel, the
following items will be displayed for 2 seconds. They will also be displayed when the DVD player is operating and the DVD
button is pressed.
