IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment covers
or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as conduit
or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the resistor
(See diagram).
* Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.) and
measure the AC voltage drop across the resistor.

which must be corrected before returning the audio product to the
owner.

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.
Distortion clip point

SP output

(The ALC will be functional
Power

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
HT-DD5000/C
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, center, 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 while 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.

When this "LFE" is lit, low frequency signals will be output from the sub woofer.
When Dolby digital signals are input, the display will light up
