The more expensive model is "active', which means the power amp is built into the speaker. You run directly from your mixing board at line level right into the active speaker.

The other model is "passive" - no power amp. That means you have to buy a power amp. The chain would be: mixing board line level into power amp. Then speaker cables from power amp to the passive Events.

Speaking generally about nearfields, most people these days find the active models a better "deal", not only because you save on the cost of a power amp, but because the power amps that are inside, in theory, are exactly matched to the specifications of the speakers. Some companies (like Genelec) are only making active models.
 
Unfortunately

I already have an amp my brother gave me a few years back and I'm low on money this summer. Should I still wait and save up for a pair of active monitors?

Passives are just as good providing that your amp pushes clean
and clear signals w/o unnecessary audio residuals that will alter the monitors flat response.
I own the 20/20's passive that are run thru a Crown CE1000 and a pair of Proto J's powered by Pyramid P1500. My 3rd set of "monitors",which in actuality are Audio-Tek DJ speakers (for home and dance uses) is run thru a Sony reciever. In monitoring,
I use the 20's and J's to analyze and judge my levels,freq,etc while incorporating the A-Teks lastly to determine how my recordings translates to the consumer format (ex. car,home,walkman etc.). Yes, active monitors offer compatibilty
within the monitors overall amplification and spkr construction,
but one can also use passives providing you have at least a decent amp!
 
Thanks

What constitutes a Decent amp?
Mine is a CREST AUDIO LA 901. I don't know how to tell you specifics about it, I don't know much about amps and I don't have the manual. I think it has two channels.
 
I havn't conciously heard any Crest Audio, but they seem pretty good. They are for live though I think. The LA 901 is 2x350 watts I think which is REALLY loud for nearfields. You'd have to keep the amp way down to avoid blowing the monitors and damaging your hearing. Also I assume that with that much power it has a cooling fan, not just convection cooled. So the noise might mess up your recordings.
 
You can't have too many watts. Underpowering monitors is much more of a problem than overpowering - because then you are asking the monitors to try and replicate clipped waveforms. Good speakers can handle fast transients that are way above their "spec" rating. Those extra watts will help with those transients.

Just use good judgement and don't crank the power amp to ten. I don't know that particular model, but 2x350 is only meaningful if you also know into how many ohms (4, 8?) that measurement represents. It sounds like you will probably be fine with that amp. The only real important difference in design between "live" amps and "studio" amps is how noisy they are. If you get a lot of fan noise from your Crest, that might be the only problem with using it in a studio situation.
 
It does have a fan

But it's actually pretty quiet, my cpu fan is Much louder than the amp.

I don't know about Ohms, but I usually don't have the amp turned up that loud anyway, thanks for the warning though.

I am worried about the noise though, it's just a very low hum, I forget the amp is on sometimes and leave it when Im not working. But will that low hum affect my monitoring much?, does it interfere with something in the monitors or something?
I'm planning to get shielded monitors.
 
Finally got some Monitors

My engineer told me that the KRK Rokits had a more sturdy cone than the Event 2020s. Hey....if I don't like em in my own place by the end of the month, I'll return them.

But I need to know more about underpowering and overpowering, how to find a balance?

Also I don't go straight from the Digi001 into the amp, I go through a Mackie 1202 first, time to change?
 
If those wattage figures are accurate I wouldn't worry about underpowering. As far as overpowering, just don't crank them to painfully loud levels and you should be fine. Where you might get into trouble and blow something is if you set up an accidental feedback loop.
 
Thanks

Just so I know not to do it, how would I set up a feedback loop? the signal goes from the 001 to the mixer, to the amp, to the monitors.
 
something from the speakers back to the mixer would create a feedback loop
 
Well, a live mic placed near the speakers would be one way of creating feedback, but there are also many others.

One common source of feedback is if the vocalist hangs her headphones over the mic stand! (Ouch!)

But you can also get signal routing sources of feedback as well. For instance, it's entirely possible to set up a track where you accidently send the recorded output back to the same fader that your input is coming from. Then: WHOOOOEEEE!

Half-normalled patchbays can be "great' for inadvertantly setting up feedback loops.

When in doubt about if there is a possible feedback loop, make sure you turn the Master Fader all the way down until you are sure you've corrected it. Your speakers will thank you.:p
 
Thanks

As far as I know, the only way I could send a signal from the speakers back to the mixer is from the mic, fortunately I am especially careful about that. I'll be alert about the headphones on the mic stand thing and I don't have a patch bay, but if I get one in the future I'll try to remember that. The signal routing mistakes you mentioned is what worries me, I'm going to be doing alot of that now that I have the monitors. I'm glad I made a habit of turning the master fader down whenever I'm about to turn the amp on.
 
I think I routed it right

But I still get that metalic buzzing sound like when you touch the end of an audio cable when the other end is plugged in.
It's a low sound, but it's distracting in the mix.

I have all the vocals routed to outs 3 and 4 and coming into inputs 1 and 2. There are no other sources coming in to the digi001.
I don't notice the sound when I listen through the headphones.
What could it be?
 
When you route back things like reverb and compression, you can accidentally hardwire in feedback.
 
It sounds like you have a bad cable or a ground loop. That is an entirely different type of loop.

Make sure ALL connected audio gear is plugged into the same outlet or strips originating from the same outlet.

Try plugging in headphones to see if the buzz is coming from the 001 or originating at the power amp.

Also make sure you are using balanced (XLR) cables. Unplug cables individually and see if one of them is causing the buzz.
 
Uh Oh

I may or may not be doing all of these things.

I don't hear the sound when I listen through headphones, but the sound also stops when I unplug the cables I'm routing with, it could be one or both, they may be quite old.

PLEASE! tell me it's not the amp, I'm praying.
