A successful live concert is perhaps one of the best examples of what great AV integrators can do with sound, light, visuals, and video. The convergence of a well planned and executed stage show can take us to another world altogether. On the other hand, we have all experienced the the screeching halt that poor AV arrangements can create, leaving a bad taste in our mouth. Everyone has experienced that ear piercing, horrible shriek when the presenter’s mic gets too close to speakers. While it may be the fault of the presenter, often times it is a problem that could be resolved with the proper setup. People may love a high-resolution video and lighting, but without good sound, a presentation can quickly lose its lustre. It’s important to make sure acoustics are considered when setting up the sound, for this reason.
AV Hardware – the Crux Behind Good Sound
Since the term “audio visuals” was coined giving equal importance to both audio and visuals, it can be correctly assumed that when audio fails, the entire presentation falls flat. So, what are the makings of a good core AV hardware setup? Although every space depending on size, shape, type of presentation will have different needs, some basic considerations are an integrated Wi-Fi or Ethernet port, Bluetooth, lots of inputs, an integrated phono stage, good streaming content, and a powerful amplifier section – all of these features may be typical of a good AV hardware setup, but the clarity and sharpness of the sound truly determines whether technology is improving the sound quality. HD surround sound features also play a role in deciding whether or not the audio is able to support the video presentations. So much depends on selecting the right AV equipment. However, to fill loopholes in your presentation sound, you can follow these tried and true steps:
- Prepare well in advance for presentations. For smoother presentations, prep time and practice with the wireless microphones and other equipment in advance will help ensure that the entire presentation runs without glitches. It is important to check if energy sources are capable of handling the draw in order to prevent the presentation audio from dying mid-way through. You should also check all the audio inputs and outputs properly a few hours before the presentation so that you have enough time to fix them if anything is wrong.
- Avoid audio feedbacks, reverbs, and unnecessary echoes. Feedback – that unforgettable shrilling noise – is arguably one of the most irritating sounds ever produced. Not only does it distract the audience, but it also kills their interest as they recover from the shock. While a trick is to keep the microphone at a particular distance from the speaker, a more permanent solution is to purchase audio equipment that is designed to eliminate feedback and cancel out echoes.
- Test the audio quality. Perhaps the smartest thing to do before an AV presentation is to meticulously test the audio quality in the room, and outside if necessary, to ensure that the sound reaches equally and homogenously across the areas within range of the presentation. Sound check is also important to reduce the risk of feedback and any other sound distortion during the course of the production.
When creating the right impact on the audience, so much depends upon the sound. While the right equipment plays a major role in determining the quality of presentations, following a few basic tips, like the ones discussed above, can make a huge difference in the final outcome of any presentation.
