Hello,

The Band:  6 members - Two electric guitars, one acoustic guitar, bass, drums, vocalist.

The Setup:  Behringer PMP 1680S powered mixer, 2 x JBL MRX 512M speakers used for FOH, 1 x JBL MRX 518S Sub, 2 x JBL JRX 112M speakers used for monitors, 1 x XTi 4002 amp, and 1 x XLS 802 amp.

Playing Venues:  Small clubs - 50 to 100 people.

We just added the sub and would appreciate some input on what amp to purchase to power it.

Presently the 4002 is running the MRX 512s and the 802 is running the JRX 112s.  The bass is using his own amp.  The Behringer is used as a mixer/equalizer only with the  Crown amps running off the main and mono out.

We are going to purchase a new mixer (Mackie) and with the new sub, the bass will run through the new mixer which will negate the need for a separate bass amp.  The new mixer will also allow us to mic the drums.

Our thoughts lean toward an XTi 2002, bridged, to power the sub.  The feeling is this would also work if we, at a later date, add another sub.  If we do, the 2002 (running in subsynth mode) will suffice for both subs.

Please give me your comments, suggestions, and observations on our setup and thoughts.

Regards,

RogerB

Hello Dakos,

Thanks for the quick reply.

The 518s is new, never been used.  We've previously only been running the 4 JBLs through the Crown amps and the bass player was using his Fender bass amp separately.  Now, with the new 518s, we'll  eliminate the Fender bass amp and will run the bass through the mixer and Crown amps, using the sub to power the lows with the bass and beefing the low end for the guitars and kick drums.  So the amp we buy will run the 518s.  Your input on our thoughts for the XTi 2002 or your suggestion on another Crown amp is appreciated before we buy it.  Hopefully, this answers your question.

Regards,

RogerB

If you use subsynth mode then this would put allot of strain on the 2002, adding to that a 4 ohm bridged mode operation, your amp will thermal protect itself before your strings get warm. Better get the 4002 and work in parallel mono when you get the second sub and till then just operate one channel. A better option is the 6002 or a used IT4000.

Hello Again Dakos,

And thanks again for the quick response!  Your input is greatly appreciated.  We'll pursue the 4002 or used IT4000 route.  It's a treat to have this forum and your expertise to help musicians who are uneducated in the Live Sound arena.  Sure saves a lot of headache (and bucks) later on if the wrong equipment is purchased.
Realizing this forum is about Crown Amps, would you have a suggestion on a mixer (Mackie or Peavey) that would work well with our setup.....16channel.  We plan on adding a Driverack PA shortly, also.

Regards,

RogerB

You probebly mean a budget mixer, correct?
If so the I'll take you to a different company, Allen & Heath ZED series mixer, the most value for the money, best in class pre amps, a very usable noise free USB port (playback or recording) and most important as reliable as it gets.

The IT4000 route is much better then the 4002 route, find one with low hours that still has some warranty left and you're all set.

Dakos,

Thanks for all your input.  You've been a tremendous help!  I'll look at the ZED series.....It all depends on what one calls a "budget mixer", lol.

The ZED 16 is the most expensive of the series ($1600), so you have the 22FX or the 24 ($670) and if you don't need that many inputs then the ZED 14 ($370) or the ZED 18 ($570) might be good.

We've (the band) decided on either the 22FX or the 24.........just trying to determine if we want FX features or not.

Thanks, again, for your help!

Oh, I found a used IT4000 at a reasonable price, so that piece of the puzzle is solved.
