8. VIDEO PROBLEM
Symptoms: the video display appears in black and white
color only or it has unstable image.
Possible Causes:
1. Video source (i.e. DVD player) is in different formats like
NTSC or PAL. Therefore, you should select the right “Video
Format” in the “Output” of the DVD player. It is because the
video display is incompatible with the video source.
2. The video out from the amplifier to the video display has
a distance over 25 feet. Therefore, you need to add an
additional signal distribution amplifier to further enhance the
signals for longer destinations.
3. You may be using the wrong cable for connection. The
cable for video signal is different from the cable for audio,
microphone and speaker. Therefore, you should use coaxial
cable for connection.
4. You may be using a low quality cable with poor connec-
tion. We highly recommend you using high quality
audio/video cable for connection.
9. AMPLIFIER SHUT DOWN/INTERFERENCE NOISE
Symptom: the amplifier turned on but there is no music
coming out from the speaker powered output channels.
Probable cause: this unit comes with multiple switch able
AC-power. For North America its 115V and for Asia and
Europe markets are 230V.
Remedy: make sure that the AC-power supply is connected
to the correct voltage level according to the local market.
See illustration below for the proper switching of the
AC-power supply level.

10. PROTECTION FOR AUDIO/VIDEO EQUIPMENT
Before you hook up or disconnect any audio/video equip-
ment, you must turn off the power for all equipments. Other-
wise, it may cause black spots to appear on the LCD or
Plasma TV screen.
11. NOISE AND DISTORTION
When humming noise or displeasing sound appears, you
can replace the supplied power cord with an AC power
cord with a magnetic device as shown in the figure below.
12. SOUND PROBLEM
Symptom: no sound.
Possible Cause:
1. Speaker wires positive and negative touch each other at
the terminals. We recommend you using the double
banana plug.
2. “Mute” is accidentally turn on from the remote.
3. “MUSIC GAIN” is on with music volume limit adjusted
too low.
