I hope you’ve had a great start to your year so far, Rentaltweeps! This newsletter is packed with new stories, columns and important industry announcements. Read on!
We’ll start with “PSYCHO!” by Nathan Haynes for our columns this week! When it comes to the discipline of audio in AV, psychoacoustics is deeply important because it studies the way sound is perceived by humans. In short, it 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 one and the same.
Another column takes a look at the camcorder market and just how much COVID-19 has impacted the use of the camcorder. Though the market took an initial hit when the pandemic broke out, camcorders have proven useful in non-traditional ways and have made a huge comeback recently. Don’t miss this great analysis by Helen Matthews over at Futuresource.
Lastly, we have a column by Pat Brown at SynAudCon. Ever wonder how to understand and 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 detailed understanding.
That’s it for the Rental newsletter this week, AV pros and fans. Don’t miss the announcement that ISE has been postponed to May below! I’ll see you next time.
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.
