this sort of signal processing does seem to be the way ahead...
wish I could:
a) afford it
and, perhaps even more importantly,
b) understand it (properly).

Hey Dave, the only buttons i touch are power switches, play, open etc :lol: Once it's set up it's just press go at the end of the day ;) There are lift buttons on the DSP to fiddle with but i want my system to sound flat in the room, another reason i like pre amps with no tone controls :cool:Quote:

Only the signal below 110HZ goes to the Antimode 8033 DSPs. So yes, in answer to your question anything analogue will also be fed through both DCX & Antimode DSPs. Just remember than only sub 110Hz has the room correction! Hope that helps :)Quote:

It can be quite odd listening to stuff as you hear bass so clearly & what before sounded one way now sounds nearly completely different & weird at times as you remember it how it was :scratch:
It's plain as day when any sub 20HZ signal is playing though, the room doesn't affect it any more.. Also no room boom at about 40Hz where it used to be annoying when anything was playing around that frequency.
Anyone wanting a review of what the Antimode 8033 can do please click here. I'll probably add to it as i become even more accustomed to what it does/ they do :)
At just over £200 each they are a steal imo, you'll not get cleaner bass from any speaker simply because you are listening in a room of finite size :rolleyes: All rooms have room modes & as a consequence delayed resonances. This thing appears to get rid of the room up to 150Hz...
Best bang for the buck i have ever had the pleasure of purchasing :eyebrows: I'm one happy chappie...
Seeing as every time i try to post this my PC crashes i'll keep it very brief :eyebrows:
New amp for my subs, the old Mackie M3000 just wasn't going to cut the mustard with 4 x 1KW bass drivers...
Enter the most powerful 2 channel amplifier i have ever come accross, the Lab Gruppen PLM14000 :) 7000W RMS per channel @ 2 ohms or 2300W RMS per channel @ 8ohms (which is what i'll be feeding). Problem solved... :lol:

One mother of a mains cable (6mm^2), there is a white 13A mains cable underneath for comparison :eyebrows:

The PLM with the Parasound on top, the PLM is tiny considering it puts out nigh on 8 times the total power :eek:

Perhaps if anyone wants some kind of explaination i'll follow it up as things won't crash with less windoze open ;)
Holy Sh1t! that should do the trick...
Switching amp by the look?
Blimey Mark, you'll be shutting down the heating in winter and driving the radiators from it, I guess? :D
You've succeeded in making my Chord look like a weakling!
Sort of Ali, yes. It uses a clever circuit kind of similar to a huge class D amp to "track" the output voltage so in effect there is only a few volts accross the output stage which is class B by the way. Therefore no filter on the output is needed.Quote:

Yesterday evening kicking out about 200W RMS per channel the maximum temp that the thing reached was as follows:- PSU 25%, DSP 30% & amplifiers 26%. All this with the fans sitting on idling speed, they can spin a lot faster ;)
It's a beast, but i can hear the difference the SMPS psu makes to deep bass & stuff below 20Hz even at moderate volume levels. Obviously once i have subs capable of 118.5Db @ 10Hz that SMPS is going to come into it's own, a 50HZ toroidal like the Mackie would be pretty useless in all honesty due to the recharge rate & capacitor voltage sag :rolleyes:
Aye, but your Chord is much more of a work of art ;)Quote:

Your neighbours must love you! :lol:
