AM/FM Interval (span)

The International Telecommunication Union (ITU) has estab-

lished 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:

Set the ON/STAND-BY button on the main unit to ON.

Press the TUNER (BAND) button until "FM" or "AM" ap-

pears in the display.

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 dis-

played, it means that the radio has been adjusted for a

10 kHz span.

To change from a 9 kHz AM (50 kHz FM) interval to a

10 kHz AM (100 kHz FM) interval:

Press the ON/STAND-BY button on the remote control

to enter the stand-by mode.

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:

Press the ON/STAND-BY button on the remote control

to enter the stand-by mode.

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 al-

ternately.

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 hap-

pens, 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

levelplaybackandVOL(Volume)arecontrolled(lowered)automaticallyafteralapse soastogettheeasy-to-listensoundlevel.

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.

0v (The ALC will be functional

during this period.)

Distortion clip point

SP output

level

Power

ALC operation

The ALC (Automatic Level Control) will begin operation immediately after the power switch is turned on.

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.

Since this control only effects the VOL level, it does not otherwise change the quality of the sound.
