Hypex Universal Class D(UcD) build coming up soon

[GeorgeO]

I am now enjoying the sound a bit better, though I need to try it with other speaker systems over the course of next week.

I listened to a variety of music-Boney M, Pamela Willaims(Saxtress), Patricia Barber, Bruce Springsteen, and bass is excellent. I now understand the effect of a 100wpc amp connected to 95dB speakers. The extra headroom gives significantly better punch and detail. For the HT application, I am confident that when connected to my Emotiva preamp processor, it will perform satisfactorily.

georgeO thanks for the info ordered 2 UCD400modules and smps today to build a 2 channel amp

 

[GeorgeO]

Ok. Its an excellent package, just take a look at a link that I posted earlier of a UcD 400 dual mono build with photographs. The builder used a Hypex soft start, I also used one, since my tranny was a 500VA capacity unit.

i have ordered an hypex400smps instead of a transformer so i guess wont require the softstart thanks

Hmm, interesting! Can an SMPS deliver the requisite current for transient peaks during music reproduction?

 

[madurai1974]

well have ordered the smps from hypex site lets see how it works out

 

[GeorgeO]

Yes, they have designed these smps units for use with their amp modules, so they should work fine.

 

[GeorgeO]

Sorry- Madurai1974, I think you will need a tranny AND and SMPS.

George

[madurai1974]

george check the pics in this thread there seems to be no transformer in the amp.

AFAIK, trafo is not required if you use SMPS but I've gathered that the traditional problem of switched mode power supply is that they are not suitable for dynamic loads and also generate a lot of EMI.

 

[GeorgeO]

Yes youre right-tranny is not needed.

 

[madurai1974]

georgeo you are right i wrote to support at hypex .com and they say no transformer reqd.
capt rajesh i also have the same doubts but the hypex forums say lotta good things about this smps let me check it out... btw its lighter than the transformers...

 

[captrajesh]

Once upon a time, they thought supersonic speed by us was not possible. I had chanced upon a scientific paper saying why it cannot be done but many fighter jets now fly at over mach 3 nonchalantly. It may also be possible in this case. All the best for your build.

 

[madurai1974]

just got the modules and smps they are so small n light need to get a compact case now

 

[crisscross]

I wonder why the Hypex SMPS are considerably more expensive than the ones at Connex for the similar power ratings?

 

[olly42]

George this is awesome Would love to come over for some listening in when ever you have time on the weekends

Im finding that the sound is only getting better. I connected it ot my Scanspeak 2 ways 87dB and find that the extra power makes these speakers sing. Good detail, and punch.Lows and highs are excellent.

How do this compare to the AKSA? I had the hypex or the new NAKSA in my wish list for a diy amp build. Also are you using the HG version along with their HxR power supply.

I also have an AKSA 55N( with Nirvana uograde) and find that this is very good. I have the standard Hypex unit.
