hypex multichannel UcD

[klipsch]

Happy New Year everyone!

I have had an itch to build my own class d amp for quite some time (few years) ... I am ready to scratch that itch with UcD.

I was thinking of building a 5 or 7 channel with SMPS ... I was hoping some folks here may have come across some multichannel threads, sites, posts, etc. that involve the use of hypex UcDs (180, 400, 700) in a multichannel setup.

I have only been able to find stereo of monoblock configs.

I am just hoping to find some further info or learning experiences others may have had with a multichannel setup as opposed to just building 7 monoblocks in 1 chasis.

If you have any to share, it would be much appreciated.

Hi,
Haven't been there in a while, but Exodus Audio use to sell multichannel hypex amps, and parts so you can build your own. You can find them at DIYcables.com. If you do not see what you want on the site, I would call and talk to Kevin, and he can probably fix you up with whatever you need. The Hypex amps are really nice.

The Hypex UCD amps are all mono boards, so as you said, you would be combining the mono boards in one case. That really is all there is to it. The only thing you need to think about is how you want to power them up.

I own the Exodus UcD400 3 channnel amp. It used to power my fronts. It's a damn good amp. I have it sitting in a closet. I think I need to fire it up again. I'm a big fan of Hypex amps.

Have you compared the ucd to a good tripath amp? The Tripath and ucd seem to be the best of the class D amps. I am a big fan of the tripath sound but haven't heard the hypex modules. CI audio uses the hypex modules in their monoblocks and those are supposed to be very good.

Yes, I was curious on the experiences of various power setups ... the amp boards themselves are mono ... I was more curious on how people were utilizing SMPS ... how 2 UcDs worked on 1 SMPS ... any multichannel SMPS (>2) out there ... if they added extra capacitors to SMPS ... any MHz or high KHz frequency cutoffs providing better results

Exodus no longer carries amp kits or amp boards and have not for quite some time ... it appears they sold out and never got a new shipment?

What did you replace it with?

The only Tripath amp I've heard is a Trends Audio amp. It was a nice little amp, but I needed a lot more power. The UcD400 is 190 wpc. I have heard CI and those are very good. I'm a fan of Class D amps. As you know, Class D amps work well in Southern California. We don't need the extra heat:cool: Like many others, I'm waiting to see Virtue Audio's new lineup.

This is true. But Kevin still supports the Exodus Audio line. My amp just got a clean bill of health from him this month. If you check out the diycable page on audiocircle, you'll see that Kevin is working on another amp.

What did you replace it with?

I have yet to replace it. I downsized my system and I am using an old receiver at the moment. Still haven't decided what I want to do. There are many options out there. I've compared to the Hypex to ICEpower amps, and for the money, I liked the Hypex better.

Saw they are still selling this multi-channel power supply, might be just what the OP is looking for:

Sounds like one of us needs to send the other an amp. :)
I have a tripath stereo amp in my queue, maybe when I get that done I will send you my Virtue Two.

Sounds like a deal. What power supply are you using?

[dvenardos]

Right now I am using the 30v/90 but when I get the soft-start I have a Condor 24v 12a/28v 10a linear power supply ready to wire up and enclose.

Oh wow you're going the battery route. I've been tempted ever since Danny has offered them. I really want to see the Virtue Pre/Dac. I think that's my next purchase. I'm still undecided about my Exodus amp. The Virtue Two is sooo much smaller. That's very appealing.

[klipsch]

Thanks for all the replies ... I checked out audiocircle and it appears Kevin is making a new mono amp ...

Also, while the Exodus MCH Power Supply looks nice ... I'm looking to avoid the heat/weight/possible noise by using a transformer at this point and am leaning towards a SMPS.

I just stumbled across a SMPS 1200 that hypex recently released the specs on to power their UcD700 ... my fronts could use the extra headroom (at least they do benefit with A/B amps) so perhaps I will wait on its release before moving forward

cheers

The condor is a linear ps, but because it provides so much current you need the soft start just like with the batteries.

The RedRocks imPULSE SMPS6060PFC SWICHTING MODE POWER SUPPLY is very popular with the Tripath amps. They will mod the output voltage to whatever you specify at no additional charge. On last year's price list it is $169.
