henry218 Posted March 27, 2014 Posted March 27, 2014 Im interested to build this modules from hypex, it will costs around $900-1200 depends if running monoblocks or stereo with 1psu (3kw is enough for me ) This will directly competing with Behringer EP4000, iNuke6000DSP or Crown XLS1000 (less watts but similar priced) BUT they all have fans that need to be modified. anyone have built this or heard this? im just wondering how good the bass will be

davewantsmoore Posted March 28, 2014 Posted March 28, 2014 If you need the power then bass will be great... if you don't need the power, then it won't be as good as something else more appropriate.
henry218 Posted March 28, 2014 Author Posted March 28, 2014 (edited) ok, i forgot to add, this is for sub duties, most likely for <80hz and it wont be more than 150hz. as this is 2ohm stable, so it opens up possibility to drives 4-8subs Edited March 28, 2014 by henry218
henry218 Posted March 28, 2014 Author Posted March 28, 2014 i think the real question is, will the ucd2k sounds better in bass than the pro amps?
davewantsmoore Posted March 28, 2014 Posted March 28, 2014 I wouldn't be surprised if modules like these were in pro amps. What type of subwoofer will you be building which requires so much power?
henry218 Posted March 28, 2014 Author Posted March 28, 2014 css sdx12 x 2 and dayton ref 315 and 390. the plan is 4 subs
henry218 Posted March 28, 2014 Author Posted March 28, 2014 I wouldn't be surprised if modules like these were in pro amps. it has to be a very expensive pro amps such as labgruppen
Antripodean Posted March 28, 2014 Posted March 28, 2014 it has to be a very expensive pro amps such as labgruppen LG are not class D but a variation on class AB. On a cheap budget I would get the EP4000. For the money you are prepared to spend I would get the Yammie pro amps, like the P7000S, where the fan rarely if ever comes on in domestic use and it's class AB which is better for subwoofers.
henry218 Posted March 28, 2014 Author Posted March 28, 2014 why AB is better for sub? labgruppen is an example for pricing
Antripodean Posted March 28, 2014 Posted March 28, 2014 why AB is better for sub? Because it sounds better is the quick answer and that is what you are wanting
henry218 Posted March 28, 2014 Author Posted March 28, 2014 Because it sounds better is the quick answer and that is what you are wanting that's definitely not my experience . i can go further to say that in bass department even mark levinson cant surpass ncore
Antripodean Posted March 28, 2014 Posted March 28, 2014 that's definitely not my experience . i can go further to say that in bass department even mark levinson cant surpass ncore Then you haven't listened to LabGruppen or Camco. Mark Levinson and Ncore amps are a joke in comparison
henry218 Posted March 28, 2014 Author Posted March 28, 2014 Then you haven't listened to LabGruppen or Camco. Mark Levinson and Ncore amps are a joke in comparison ok, im interested. which model?
Antripodean Posted March 28, 2014 Posted March 28, 2014 See if you can try out the LG IPD series as a starting point. With Camco I like the Vortex but they also have newer models.

Antripodean Posted March 28, 2014 Posted March 28, 2014 you do realised that the labgruppen is class d right ? and camco is class H, neither of the 2 is AB No, the labgruppen is not class D. Nor is the Camco. Both are a variation on class AB. It's a common misconception about these amps because they use SMPS.
henry218 Posted March 28, 2014 Author Posted March 28, 2014 No, the labgruppen is not class D. Nor is the Camco. Both are a variation on class AB. It's a common misconception about these amps because they use SMPS. it maybe for the old model i dont know, the web page defined their amps as class TD (tracking class D) and no detailed definition for the cheaper models which i can safely assume ordinary class D. as for camco it says on the specs that it is class H. but can u imagine 1900w @2ohm, how big of heatsink to dissipate the AB? its just impossible.

Class TD is a variation on class AB so your assumption is reasonable but incorrect. The naming of the Labgruppen's is about the power supplies which is where most assume it is class D. Class H is a variation on class AB ,,, and that's why they have fans You really should try the P7000S given your requirements.
henry218 Posted March 28, 2014 Author Posted March 28, 2014 Roger, High power, space efficiency, and proven reliabilityThe fP 3400 is a lightweight and space-saving power amplifier, ideal for use in high quality touring sound systems as well as in demanding permanent installations. Heat and cooling are fundamental problems in many extreme high power amplifiers similar to the fP 3400. Addressing this issue with innovative thinking, Lab.gruppen patented a high efficiency amplifier topology that represents a major evolutionary step beyond the typical Class D design. Designated Class TD® (for Tracking Class D), this breakthrough technology achieves the same high efficiency as Class D, while avoiding the inherent drawbacks. In particular, Class TD avoids the steep recovery filter in the audio path that is required with ordinary PWM Class D designs. Although overall efficiency is comparable to Class D designs, Lab.gruppen’s Class TD maintains the same pristine sonic quality as a traditional Class AB amplifier.
Antripodean Posted March 28, 2014 Posted March 28, 2014 Henry That is the marketing spiel. You do note that it never says it is class D (in fact it's "beyond class D" etc) and that it sounds like a class AB. That's because it's a variation on class AB. To cut to the chase, the patent tells the story and is an interesting read.
henry218 Posted March 28, 2014 Author Posted March 28, 2014 Roger, thanks for the yamaha p7000s recommendation, seems good for the $ cheers Henry

davewantsmoore Posted March 28, 2014 Posted March 28, 2014 Henry. Roger is correct. What both these types of amplifiers are essentially doing is making a A/B/AB amplifier with modulated rail voltages to increase it efficiency. Excuse me if that is an oversimpification.... but the point is that it's not "Class D"
davewantsmoore Posted March 28, 2014 Posted March 28, 2014 That's because it's a variation on class AB Or A or B It appears that LG are actually using a class B amplifier.
