I'm curious why you would say the softstart. Is it because you use a heck of lot of capacitance? I don't get turn on thump even with my UcD400s, 2x 600watt toroids, & ~35-40kuF of capacitance.
G'day...KevI've been searching amp for 2 months I reckon Hypex amp will be the best amp in the market, I hope I can end up my last hunting with hypex.Before that I got some questions about this hypex amp.1) what is the difference between AD and ST version in sound quality?
2) is that possible to replace the caps on UCD power supply? for ex with blackgate or rubycon?
3) does the chassis fit for 2 channels dual mono configurations? 2 channels, 2 power supplies and 2 transformers?
4) what is the benefit using RFI/DC filter? ..
5) I'm from Australia is it possible to use 240 VAC transformer?
Hi Kevin,Is this amp sensitive to cable and grounding? I have used digital amps before and they all had hissing sound one way or another. Ken
how does the amp do with single driver, high efficiency speakers?
That looks like the FIRST amp kit I'd EVER consider!Congratulations.So how much heat does this puppy pump out? It would be sweet to have my brother carve me up at least a wooden face plate, maybe sides, too. Any problem with that?-Mike
So why is the case so big? It looks like it could be half the width and shorter in depth.Darren
Ok.. for you bargain hunters who are willing to break out the soldering iron & provide a little free labor we are now offering the basic 2-channel Hypex amplifier kits. The UCD-180 versions are now on the site and I'm working on the UCD-400 version next. Hypex Amplifier KitHi Kevin,So what is the difference between the SG and the HG supply. On the UCD400, there are two? power supplies to make up the HG supply. Could you explain a bit more? On the 400 supply, you are using a 500 VA transformer? That would be for the single supply. If left on, what do both amps draw in idle mode? If not much, concerned what the need for standby is for?Ray
Ray: From his website:"The Hypex HG (High Grade) power supply has all the functionality of the standard power supply with full DC protection, on/off mute toggle and built-in bridge rectifier. What differentiates the HG model is the use of premium slit-foil electrolytic capacitors and ultra-soft recovery diodes bypassed by snubber caps. In addition, this premium supply offers a full 40,000uF of capacitance to supply two full UCD-400 or UCD-180 modules."This be true. I wrote him that question about 3 this morning. So I really did not look at the site to well. To think you can get a killer stereo amp in a complete kit form for $500. That's a steal.RayThat answers all but your idle power question.
