Ok so after a bit of a break the buying of a dB-Mark 28+ fell through I’m still interested in dB-Mark range just wondering when it comes to the dB-Mark range when they went to ‘+ series’ what where the changes? I can’t see anything too significant.
Is the software still out there or will it become obsolete and linked to old Windows now they are no longer in production? Is it the same as old computer hardware or smartphone software where at some point you can no longer run it unless you keep your computer stuck in an old operating system?

(Though you might need to be on a PC rather than a phone to see all of those options.)

Thanks, shame really that DriveRack PA2 has such good computer compatibility too. May have to be the DR260 as atleast there are videos on YouTube. All the videos for the dB-Mark DP28+ seem to be in Malaysian.

All of those DSP's will allow you to vary the crossover frequency and to flip the polarity of each output if needed. They will all also allow you to delay each output as needed - normally, this plus polarity flip & correct choice of crossover shape and order should be enough to get the phase lined up.

A more advanced way to fine tune the phase is with "all-pass filters" (Edit to add: or continuously variable phase control). The Behringer DCX2496 & dB-Mark DP28+ do offer this feature; the 2 dbx models you mentioned do not FWIW.

Edit - thanks Smitske!

Thanks! (By the way is there an easier way to Thank people as I see on peoples profiles a thanks counter?)

Sorry, I was mis-remembering what they call their continuously adjustable phase parameter. Post updated.

Since when does the dcx offer all-pass filters?

preferences/warnings on these, which would you choose? - DBX DriveRack PA, DBX DriveRack 260 or dB-Mark DP28 +. Which I have saw all at a decent second hand price but I have also seen the DBX DriveRack PA2 is IOS/Mac compatible which appeals as it’s what I have, it also has great reviews!


I saw the DP-Mark was recommended over the Behringer DCX2496.

I was also advised to get a DSP with ‘variable crossover frequencies and a phase button in order to flip the phase’ I can’t see the mention of phase on the DBX drivers lack does it have one? Is it called something else?

Reading all this hurt.

An easy into for you into pa world would be to sell your speakers and buy something cheap to get you started.

For example, Peavey hysis tops are very cheap, not the best sounding but still cheap.

You can also pick up the twin 15 bass bins for next to nothing or look for a pair of single 18 bass bins and a pair of 12 inch tops. You could use a simple crossover for that and not need the more complicated dsp. 

If you want my opinion, do not buy inuke amps, use the money and buy better second hand amps, like the qsc 3602. Or the older rmx the 2450 would be fine for a pair of single 18's as you could do what you talk about often, run it in bridged mode. 

Or find a pair of twin15 mid tops and just use those full range for now adding dedicated bass when you can afford it. With the twin 15 you would only need 1 amp and no crossover. Just an eq 1 amp and 1 pair of speakers and they can normally be tweaked to sound ok. Obviously no massive thumping bass, unless you can afford something like the nexo msi tops. But I have not seen any of those since I sold a pair many years ago.

In bass no one can hear you scream!

+- Banana Plug Binding Posts on x4 of Jamo's and +- Jacks on the x4 Boxes with Black Widows in. I will eventually change to Speakon.

Ok as said elsewhere it will help if everything has speakon on it. No idea why your using those jamos. Those are some badly made hifi lofi speakers. Jamo made some truly dodgy stuff and we're so lazy they literally stapled drivers to the chipboard like the dome tweeters on yours.  Maybe ok for DJ monitors at a school disco. Sell them to someone who doesn't know any better (misguided nostalgia vaule) and get your self a pair of cheap ev sx300,bargain on eBay etc. Those and the JBL boxes should make your life easier and sound better. Give you a better foundation.

You can but there are limitations to the file size and resolution.
