Flashcards
0/15
No Sound
Ensure all cables are securely connected, check the power supply to the devices, and verify the sound source is playing.
Intermittent Sound
Look for loose wire connections, damaged cables, or issues with the sound source.
Distortion
Adjust the audio levels to avoid clipping, ensure speaker impedance matches the amplifier, replace damaged speakers.
Humming or Buzzing Sound
Check for ground loops, ensure cable quality and shielding is adequate, and inspect for electromagnetic interference.
Feedback
Reposition microphones away from speakers, adjust equalizer settings, use directional microphones.
Low Volume
Check the amplifier's power, adjust input gain levels, and make sure volume limiters are not engaged.
Excessive Bass
Adjust the equalizer to reduce low frequencies, position speakers to minimize resonance, and use high-pass filters.
Lack of Clarity
Calibrate the sound system, check for phase issues, and replace any worn out components.
High-pitched Squeal
Reduce microphone gain, increase distance between the microphone and speakers, and use feedback suppressors.
Uneven Sound Distribution
Examine speaker placement and angle, adjust sound system equalization, and consider using room correction software.
Microphone Popping
Use a pop filter, ensure proper microphone handling, and educate speakers on proper mic technique.
Background Noise
Identify and eliminate the source of noise, use noise gates, and apply directional microphones.
Delayed Audio
Check for latency in the signal chain, adjust digital processing settings, and verify sync between video and audio if applicable.
Overheating Equipment
Provide adequate ventilation, ensure proper rack spacing for equipment, and check for faulty cooling fans.
Crackling Sound
Inspect cables and connectors for damage, replace failing components, and prevent overloading connections.
