DBX ???s

#1 Post by Rockboy »

I see that DBX has a $100 rebate on the PA & PA+ until the end of the month.
With the price from Northern Sound and this rebate this is a pretty sweet deal
for a new one.

My question is do I really need one????

I have Crown XTI 2000 for T-39s and tops.
I will be buying a A&H QU-16 or Behringer X 32 Producer soon.
With one of these digital boards and the crown amps, I don't see
the need to buy the DBX. Please help me make sure I am not
missing something !!!

Thanks - Robb

First off...I'm extremely jealous of your board acquisition. If the Crowns can handle crossover and limiting duties, seems you could pass on one. I don't see where either of the boards themselves would be cause to eliminate the driverack...it would be the amps with similar functions would do that.

Do either have RTA and 31 band auto EQ capability?

You're right.... that is a good deal. too good lol. I also have a crown xti 4002 and 2000.... and now I want this.

I planned to buy my coworkers computer from him for around this price... with Smaart installed, and pick up the rta 420 mic along with it for around this price... decisions...

any insight on the functionality of the PX series in comparison to the PA Plus? I already have limiting handled so no questions there... How is the RTA?

I recently got the PA+ and RTA mike, Bruce stated the P series i.e PA, PA+ and PX all do the same thing but he found the PA was a little slower at RTA and the PX, because its for powered boxes, only has a two way cross over, which he states is all that needed for BFM cabs, because of the passive crossover in the tops.
My impression of the PA+, its the bee's knee's. RTA is quick, accurate and that eq section has real flexability, easy to set up small, light
software, upgradable, AFS wizard. I bought a DBX dual 15 band eq before the PA+ plus thinking after I set the PA+ when the system goes out to rent if the dj so desired he can push acouple of sliders up to his liking, but really I forgot the mixer will have some eq in it, so a siple rack is just mixer, PA+ (DSP) and amps. How cool and simple is that!
So what im saying is the PA+ is a winner

Thanks for the input - this leads to the follow - up ?

Is the PA+ worth the $100+ difference ?
Additionally, the PX comes with a RTA mic.

Thanks - R

If you'll only be running a two way system, I don't see any reason not to use the PX.....especially with the bonus of getting the mic.

Yep.....from the manual.

The Filters are used to divide the input signal into two frequency bands. This allows the user to drive the speaker in its optimum frequency range and send each output separately for more efficient use of amplifier power. Appendix A.5 illustrates each of the available Filters. The signal present at the Main (OUT) outputs can be adjusted using a High-Pass filter. The signal present at the Subwoofer (SUB) outputs can be adjusted using Band Pass filters consisting of Low-Pass and High-Pass filters. When editing Filter parameters the frequency band is indicated by the highlighted OUT or SUB in the top left corner of the screen. The High-Pass
or Low-Pass filter being edited is indicated by the highlighted edge in the graphics area.

For each High Pass filter there are three parameters:
Frequency
Adjusts the frequency of the High Pass filter from OUT (below 20Hz) to 20KHz.
Type
Selects the filter type. Selections are BW 6,12,18,24 for Butterworth type filter with slope of
6, 12, 18 or 24 dB/Octave and LR12, 24 for Linkwitz-Riley type with slope of 12 or 24 dB/
Octave.
Gain
Sets the gain of the selected output band. (-INFdB to +20dB)
For each Low-Pass filter there are two parameters:
Frequency
Adjusts the frequency of the Low Pass filter from 20Hz to OUT (greater than 20kHz).
Type
Selects the filter type. Selections are BW 6,12,18,24 for Butterworth type filter with slope of
6, 12, 18 or 24 dB/Octave and LR12, 24 for Linkwitz-Riley type with slope of 12 or 24 dB/
Octave.
5.6 Output Parametric EQ (3-band)


I'd suggest that everyone go online and read the manual of EVERY piece of gear that you are considering before you buy it. No need to guess when everything is so readily available.
