There's also kind of a I guess you'd call it a misconception that powered loudspeakers have less headroom if you will. The reason being is the amplifier inside is built specifically for this particular speaker so we can kind of touch base on that a little bit but essentially what I wanted you to understand is a active loudspeaker is getting its power source from an internal amplifier built within the enclosure itself. Okay?
Now we're going to talk about a passive loudspeaker. Imagine this same thing but the amplifier is not built inside. There is no components, nothing, no tricky electrical stuff. It's literally just the tweeter in a two-way system and the horn and then you just really have an insert essentially and there's some crossover points as well. But anyway, they require an external amplifier, and I'll kind of walk you over here, something along these lines that will actually send it the power.
Now one thing I want to make sure everyone takes note of, there's a huge misconception with these knobs here. Everyone seems to think that this is a volume knob. It is not a volume knob. It is an actual level or an output knob and this can definitely be displayed by the fact that I can turn these all the way up when the amp is on and yes you will hear a volume increase but that's because I'm sending more juice to the speaker. But if I have this plugged into a mixer and I turned the main levels all the way down you will hear nothing yet these volume knobs are up all the way. So again just kind of wanted to touch base on that. A passive loudspeaker system requires an external amplifier which in return will require cables to come from the amplifier to go to the speaker.
So now that we understand the differences in the two major type of loudspeaker systems we're going to talk a little bit about applications. And again, this is up to interpretation but I'm just going to give you some rules of thumb that will kind of help you figure out what type of system will work best for you. So we'll start off with your mobile DJ. This is a customer that might be doing the gig in different types of venues each night. He has no idea where the stage is going to be before he shows up. I mean it is just completely mobile.
