How important is using a DI box when playing directly into the PA?

It depends. A DI box converts your amp's line out signal to low impedance, and some venues will absolutely require it for you to plug into their system.
If you have your own PA and are playing smaller clubs you can plug your line out right into the "Line" input in a mixer channel, using a regular 1/4 inch instrument cable.
Low impedance is critical for long cable runs, like with a snake. For shorter runs, say under 25 feet, high impedance is fine.

Not sure he meant a line-out, Rick - though what you say about that is spot on.
If you meant a mic:
Just to be sure its clear - you ONLY need to use a DI box if you using a high impedance mic into the PA. You don't use one if you have a low impedance mic. Portable/band style PA's often have high impedance ΒΌ" inputs, but as far as I know on most, if not all PA's those don't go through the mic preamp circuit and so may not have as nice or as adjustable a tone. The DI box allows you to go in through the low impedance/XLR inputs so you will be using the PA's mic preamp - and as Rick said because the signal exiting the DI Box is now low impedance, the cable length no longer matters as well. Note that house-style (semi-permantly installed) PA's generally don't have high impedance inputs - DI boxes MUST be used. The sound guy will have them - because that is almost always how he will interface the bass and the keyboard player to the house sound system.

I have an EV RE10..and it has some pretty good tone.
Could I go directly in the PA mixer line-in...? I was hoping to eliminate any other gear by simply bringing the right mic, and running it through the PA. ALot of legendary players do this and I have finally figured out why..a nice change from all the hubbud of tube amps and gear mania!
This is the most top of the toppest secret secret, in the amplified blues Harmonica world today. Shhhhhh!
No gear to haul, one mic, great tone~, and no hassle...
Ahhh, fuck it...give me back my Masco MA17 w/1X12 cab anyday...there is nothing like a good junkyard dog "bark", or the "crunch", only a tube amp will give you...but it's a nice idea to switch your "sound" around a little. Nothing worse than the same sound all night...wears me out.(unless your Kim Wilson or some other master player who has the ability to keep it interesting ALL NIGHT.

The EV RE10 is a low impedance mic. Plug it straight into the PA and blow, baby, blow.
