Getting to know you.

7) Measuring Light

There are many goals and many purposes for this project that you are involved with. There are many things that need to be done.

The top layer has to do with ensuring that the presentations in the auditoriums are the quality that the CEO of the company intends them to be – acknowledging that not every room is a Palace of Perfection. Another layer has to do with ensuring that each patron is satisfied with what the facility and staff have to offer, which also includes an educated staff that is able to communicate intelligently with patron and tech staff.  Fortunately, they don’t all have to be done at the same time. They can be added too and tweaked and made better and more as time goes on.

So, if at first you don’t have the organizational support to download DCPs onto a USB drive, then get the DCPs into the Media Player/Projector system right now – you can still download some audio and light measuring tools, and experiment with them until you can use them easily in a dark room.   Continue reading “7) Measuring Light”

6) Measuring – Sound

Audio (Basics): Part 2

Hi again.

At the very end of Audio (Basics), Part 1 we introduced the concept of Frequency when discussing waves. We also mentioned some basic information about the speakers in the room, which create the waves that we eventually hear. This article will build from there. You can skip all of this and you can still talk to a technician, but it is really simple. It just looks long because there are a lot of examples. Continue reading “Audio (Basics): Part 2”

6) So Now You Want To Measure Sound Level

Hopefully you have read through the post named Basics: Audio (Sound), Part 1 and Part 2. It is good to have a basic understanding of frequencies and speakers and surround and amplifiers and level and Loudness. Hopefully you’ve noticed some of the many ways that the human hearing system has made things “interesting” in normal life, and while you have walked around your cinema theaters since learning more about these things.

What’s It Mean? Contrast…

Let’s go through a few terms that everybody uses, but have a specific meaning if you are going to get an idea across to the Tech Team to get a problem solved.

First, Contrast – Simply said, in the cinema, it is the range or difference between what looks like white and what looks like black on the screen. In most auditoriums, there is no real white on the screen or real black on the screen. There are many reasons for this, and it will always be. But there is a range that each room is capable of, and the equipment is in a war to try to make it stable, which it always loses. Continue reading “What’s It Mean? Contrast…”
