What is audio visual system? An audio visual system, commonly referred to as an AV system, is an electronic system developed for multimedia presentations and consists of equipment used for the broadcasting, recording or playback of audio and video content. An AV system typically includes some combination of display devices (projectors, TVs, monitors), audio equipment (amplifiers, speakers), video sources (DVD/Blu-ray players, computers), signal processing equipment and cables for transmitting audio and video signals. With the right components working together properly, an AV system allows you to share presentations, videos and other multimedia with an audience effectively. However, there are some common mistakes people often make when setting up or using their AV systems that can negatively impact the experience. In this blog post, we will explore the top 10 audio visual system mistakes you might be making.
#1 – Not Testing and Troubleshooting Before an Important Event
One of the biggest mistakes is not properly testing your entire AV system well before an important presentation or event. You want to make sure all the components are connected correctly, the latest firmware and software are installed, everything is displaying and playing audio properly. Take the time to do some full run-throughs using your actual content to verify there will be no issues when it’s live. Proper testing and troubleshooting allows you to find and resolve any problems beforehand rather than dealing with them during an important event.
#2 – Assuming Plug-and-Play Will Just Work
Subheading: Many people mistakenly assume that as long as all the components are connected, an AV system will just work seamlessly with a plug-and-play approach. However, various settings often need to be configured across the different pieces of equipment. Things like input/output selections, audio/video settings, resolution and refresh rate matching all need to be verified. There may also be firmware or driver updates required. Something as simple as outdated HDMI cabling could cause interference. Taking the time to properly configure all the connections and settings is important rather than hoping everything will magically work on its own.
#3 – Forgetting to Turn On Sources and Connect Devices
Subheading: A silly but common mistake is forgetting to power on the actual source components like Blu-ray players, laptops or streaming devices before starting a presentation. People also forget to connect these sources to the correct inputs on the equipment like the projector, television or receiver. Then when trying to share content, nothing shows up because the input is not live. Always remember to turn on all sources, connect them to the correct inputs and select those inputs before starting presentations to avoid wasting time troubleshooting a simple oversight.
#4 – Not Adjusting Display Settings
Subheading: Projector and display settings often need adjustment beyond just turning the unit on. Aspect ratio, resolution, color settings and more all require tweaking based on the source content and room environment. Improperly adjusted settings can ruin the viewing experience through distortions or colors being off. Take the time on every projector or display to optimize settings like aspect ratio, resolution, color, brightness and contrast using test patterns before an event. This ensures the sharpest, most accurate presentation.
#5 – Using Inadequate or Underpowered Equipment
Subheading: Pushing an AV system beyond its intended capabilities leads to issues. For large rooms or audiences, equipment may not have enough power, throw distance or processing abilities. Trying to get great quality from low resolution sources on enormous displays never works well either. Evaluate room needs honestly and select equipment suitable for the required scale. Don’t skimp on quality for the sake of saving money initially if it means the system won’t perform as needed in the long run.
#6 – Mixing Old and New Equipment
Subheading: While it’s tempting to reuse older equipment to cut costs, mixing components from different eras can cause compatibility nightmares. Newer sources and displays rely on features like HDMI that older AV receivers and projectors may lack. There may be missing ports, unsupported resolutions or obsolete connection types between mismatched equipment. Stick to modern, compatible options whenever possible rather than dealing with glitches from technological generations clashing.
#7 – Failing to Properly Calibrate Speakers
Subheading: Speaker placement and calibration makes a world of difference in sound quality yet often gets overlooked. Factors like directionality, distance from walls, crossover settings and proper level balancing between speakers require adjustment. Take measurements and do test recordings to optimize positioning. Calibration tools can validate balance and alignment. Spending time on acoustics ensures sound meets the room rather than leaving listeners struggling to hear different components of the audio mix.
#8 – Not Considering Ambient Light Issues
Subheading: While most people focus on video and audio quality, ambient light is frequently neglected in AV system design and setup. Too much light causes video levels to wash out and colors to shift on displays. Eye strain also develops more quickly. Options like light blocking shades, dimmable lighting zones and dark wall/ceiling finishes help video remain visible, yet maintain comfort. Ambient light management deserves attention equal to other technical aspects of the system.
#9 – Relying on Default Remote Control Settings
Subheading: Factory preset remote codes rarely match all components. Ensure your universal remote is programmed to control every single piece of the AV system through detailed setup menus. Convenient “one touch” access to all gear is impossible with default settings. Take the time to custom tailor remote operations rather than dealing with equipment responding incorrectly or having to juggle multiple remotes.
#10 – Ignoring Firmware and Software Updates
Subheading: Just like computers, AV equipment benefits from applying available firmware/software updates. These regularly fix bugs, improve compatibility with newer sources and add useful new features. Model year-old equipment works much better with its latest internals applied. Take an hour to patch everything before major events to ensure peak performance and reduced failure risk over time as systems are exercised heavily during presentations.
In conclusion, taking the time to avoid these common mistakes can make a huge difference in the reliability and user experience of an audio visual system. Proper setup, testing, configuration and maintenance are important factors to consider that often get overlooked. Addressing issues like ensuring all connections are made properly, adjusting settings appropriately, calibrating components accurately and keeping software up to date helps guarantee any AV system will deliver excellent presentations or entertainment experiences for its audience or users.
