Listen to the audio:On today’s Tech, No Babel: Video production: What’s a DA and how do you use it?
DA doesn’t stand for district attorney (in this case). It’s distribution amplifier. Let’s look at those words. Distribution means to send something to different places. An amplifier increases signal. So, a DA amplifies and then splits the signal. That’s important. A splitter takes a signal and splits it in half. A DA starts with a signal of a certain strength and then splits it to send the same strength signal to both locations.
Why would you use it?
If you want to send the same thing to two locations, a DA is a perfect choice. Looping out of the projector might not give you the best results.
There are multiple types of DAs. The most basic ones are 1 in and 2 out. Others can be 1 in 4 out. One of these might be a great idea for lobby TVs or to a local monitor, two projectors, and a confidence monitor.
