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.
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.
Quality Power Cord:
