I use Xilica xp4080, got it second hand for below your given budget,
Never given me trouble, very powerful processing unit. 
Control software is nice on laptop 
but the screen on the unit is very basic so wouldn't want to be building presets on it. 

Used to have a dcx, for the price their great, but I would never go back after owning the xilica

Db Mark processors have been around quite awhile now and only heard/read good things, nice to have a warranty too.

Yea the 208 looks like a very interesting proposition to me, can't afford to spend £500 + the time to measure my mf/hf tops phase & magnitude In an anechoic chamber, in order to build the correct FIR filter, but that's what I'd like to do.

To much money to spend on a crossover that could suffer from poor quality components, just don't trust T-Racks stuff, the bits I have used have been a little better and more reliable than older berry (we all know is terrible, some get 3 yrs outta a DCX, many get 4 months before a solder joint or budget component fails) , but the jury's out on new T-racks until others have used and tested these new LMS products.

I'm sticking with an XCA for now, better adda than the 4 series XTA, we tested it at dBs plym uni, obviously the 5 series is still the bees knees, but tbf I'd rather aim towards an armonia setup

So yes continuous peak limiting = clipping = distortion and may lead to higher RMS value.

RMS compressor will compute RMS value over a period of time, and will lower the signal for a certain period of time if the computed value exceeds the threshold.

pseudo-RMS can be achieved with peak detection + long time constants (ie attack set  to the min, and release set to the max) but that's not an optimal method

Ah nice one JBK, I'll do some more reading too. We often use the xca so I guess I should learn more about that compressor too.

I thought too much compression raises RMS?

We stopped supporting 9088X Soundwebs a few years back, some of them are old enough to drink in the US now.
Fine if you want something to mess about with, just wouldn’t trust them in a critical / might lose trade situation. (We’ve deployed a shtload of them over the years).

Soundweb London’s can be got at a reasonable price second hand now, or Biamp TesiraForte’s for example. (If free form architecture is an important consideration to you).

The new tracks looks (named t.racks DSP 206, 408, etc) quite powerfull for the price, on a french forum a few guys are testing it and to them it's a DCX Killer as it has more feature, models with more in/outs, for a reasonable price, so might be an option to some.
can't comment on quality/durability though

If you like LR48 filters, the DCX runs out of processor memory, so you can't deploy what you want at all times, and you have to compromise. The glitch on audio when changing parameters is a bug which is distracting.


DCX is cheap and reliable enough, but needs a revamp to still compete with more modern stuff.


DB Mark USB/Laptop GUI is a doddle for set up, and you can deploy any combination of EQ/X-Over/Limiters/routing without hitting processor memory limits.

Nothing wrong with a DCX, just looking a bit dated with a few glitches.

DBX drive is utter poo, DB Mark stuff is kinda not Tour proven and more money, Behringer offer massive bang for buck!
