Happy Friday! Anyone have exciting plans for the upcoming three-day weekend? Well, kick it off with some great columns about various AV topics.
Our first column this week is “PSYCHO!” by Nathan Haynes. Psychoacoustics is deeply important to the discipline of audio in AV because it studies the way sound is perceived by humans. This helps us know why the quality of some sounds is better than others. Find out why Nathan calls psychoacoustics the “great quantifier of why AV,” and why he says it proves AV and IT are not quite the same thing!
Column two looks at the camcorder market and how COVID-19 has impacted the use of the camcorder over the last few years. Though the market took an initial hit at the beginning of the pandemic, camcorders have proven useful in non-traditional ways. They’ve even made a huge comeback recently! Don’t miss this analysis by Helen Matthews over at Futuresource.
Our last column for today comes from Pat Brown at SynAudCon. Ever wonder how to calculate voltages in loudspeaker systems? Important for even the most temporary install, voltage isn’t something that should be guesswork. Check out “One System, Three Voltages — Make Sense?” to get a better understanding for your next project.
That’s it for the week, guys. I hope you have a great weekend, and I’ll see you soon! See ya!
Psychoacoustics has extreme importance when it comes to studying and pursuing a career in the audiovisual industry, specifically in the discipline of audio. (It can be applied to video too — that’s for another day.) For those who have already been versed in this level of audio nerd status, read on my fellow friends
COVID-19 has had a lasting impact on the professional camcorder industry. Its initial impact appeared to be negative, with the first half of 2020 seeing a significant downfall in sell-in compared to previous years. Lockdowns, social distancing and event cancellations affected markets across the globe, resulting in the majority of traditional end users halting investment in next generation camcorders, both due to the cancellation and postponement of events, budget limitations due to market uncertainty, as well as competition from pan-tilt-zoom (PTZ) cameras.
In this article I have shown the factors that determine the output voltage of the amplifier in a transformer-distributed loudspeaker system. As you can see, these systems seldom output their rated voltage, which is a source of much confusion.
