Hypex amp question

UCD400s will be enough with the TB2s (my UCD400 based amp was originally built to power TB2s), but the Matrix 801s and 802s are power hungry and that extra power will help when listening at higher levels.

Go for x2 mono modules with a linear power supply, and over-spec the PSU if possible. I have the UCD700 transformer with my UCD400 H+R softstart amp and it's superb. Powering ATCs here.

great thanks. Is the UCD700 to big for TB2 or does it work fine? Would be a great setup but can I run both sets of speakers through the same amps using a kind of AB switch? I need to keep costs down and want to upgrade later.

Finding the right amp: How does the versions (HG, H+R) differ? I'll build two mono modules in one case right?

[AlexK]

A 700W amp will only be too much for a speaker if you turn it up past the speaker's power handling limit.

An A/B switch would be fine - although make sure you use a good quality one. I couldn't recommend anything because I haven't used one...

hg is higher ver then std, better opamp in hg,
maybe you should ask this question on diy.com forum
there's quite big thread about hypex, with bruno putzey (designer)
visiting it from time to time, so it's a first hand info there

if I remember correctly tb2 are 140W,
so you have massive headroom with ucd400
actually ucd 180 will do just fine in smaller studio
how loud you want to go ?
I got ucd400hg connected to pmc ib1s - I can go to 100dB SPL, house is really shaking, and my monitors and hypex are looking at me and laughing -'is it all you got ??'
I tried to make it louder, but it was kinda of strange feeling, when music is so loud, you can't actually hear your thoughts
and got feeling next second everything will collapse out of noise!

PMC recommends 40W to 150W amp for TB2's (8ohm). UcD180HG's will go 180W into 4ohms or 120W into 8ohms. My studio is roughly around 30m3 and the UcD180's push plenty enough for the size of my room without struggling at all.

Not sure about A/B switching unfortunately.

I have a good offer for matrix 801s2 and would like to get both running with the same amp. I think usd 400 is to small for that? I usually listen at a low level.

A UcD400 will easily drive an 801.

Had the 801n in the studio for a while. First had them powered with my UCD400 & it sounded very wrong, woofy lows & harsh highs, & something missing in the mids. Then switched to a pair of Classe ct m600 mono blocks & they sounded perfect.

Ed, have you heard that same UcD400 driving other speakers? I wonder if it was working properly. It could be that you just don't like it but I have never heard of it being described as woofy or harsh.

Yes, I powered my Dunlavy sciiia's for a long time with them. The 801N seem to need a huge amount of power to sound right. When the 801's & classe left the studio I went back to the hypex dunlavy combo. I was so used to the clarity & mid fullness of the classe's that i had to get my own. by the way...With the dunlavy's it was much smoother than with the 801's.
So now I have a combo of classe Ca-m600 monoblocks & the dunlavy sciia's. a huge improvement to the hypex. In the future i might get the 801's back in here as it was the best monitoring set up I have yet worked with.

I just got the pair of B&W m801 S2. I just listened to some music with a bad sony 110w hifi amp and it sound very nice. But a little like ed discribed. A bit harsh and some missing mids. But very clear with a nice low end even at low volume.

My plan is to try it with hypex UCD 700HG. Does anybody tried this combination? Or should I try something else? After I did this little listening test I decided not to buy the pmc tb2s.

[siamhatter]

I need a little help with this project. I looked through some forums but I think here are the people who use the hypex amps for mastering and I would be great if you can give some tips which parts I need to order.

1. is there an advantage to build two mono blocks instead of one stereo amp?
2. I think I'll go for the ucd700hg. which power should I order
3. beside the connection material, do I need anything else? switches, plugs etc.?
4. seems modu in italy has nice cases. How big does it need to be? Is it easy to build everything? @ rondr: did you order the frontplate extra?

Thanks!

1. I would like to find it out myself
2. ask guys in hypex, they are very helpful, generally hypex service is top notch; I think there's a power supply for ucd700 in their catalog
3. yes, you will need power socket, input xlr sockets, switch (if you need one), speakers terminals, and this is it I think
4. I took 2U from modu for 2 hype amps and 1 power supply, there's enough room for another power supply, or even another pair of amp modules, I got 4mm front plate, I think you can choose several different from modu - get in touch with them (modu.it) to be sure

good luck

The advantage to mono blocks is more power supply current capability.

The disadvantage is potential ground problems.

ok,
but what if you fit 2 power supply into 1 case with 2 amps
would it make it a mono block ?
also potential ground problems are avoided isn't it ?

[Bob Olhsson]

That's true. The only other advantage is shorter speaker cables.

I think longer speaker cables are not really an issue (but maybe I am wrong?)
thank you for answer Bob,
it's great news, I am gonna give my hypex ucd400 some extra power supply soon and it will make my setup double/single mono block ? I would call it

[siamhatter]

With the speakers cam very expensive bi wiring cables that are very short. This would be a point for 2 mono. But 2 cases and 2 power supplies = more expensive.

yes, but we know expensive speaker cables are bit of audio voodoo

[Bob Olhsson]

You want to use at the very least #12 speaker cables.

[siamhatter]

just checked, 2 ucd700 mono is more expensive than I thought. Maybe ucd400 with option to run the speakers bi amped later. Ton weak for B&W Matrix 801?

[Riccardo]

Mine is a dual mono, two transformers, two UCD400 with XR, two HG supplies, one soft start in one fitted with much patience and planning in a single Modu case. Weights a ton.....

[siamhatter]

does anybody know if the modu galaxy case has enough heat sink for an ucd700 amp + pu? I decided to go for 2x mono.

My studio is rather small and currently Yamaha HS80's with 75W amps are more than enough SPL.

Any advice on this?

At 0.1% THD it is approx 65W.

[siamhatter]

Hello, I think I do need some help. I bought two ucd700 hg hxr and two ucd700 pu. The transformers and plugs etc. I'll get in another order from hypex.

most of the connectios seems to be very simple but i do need helpt or a colour coded wirering diagramm or somebody who helps which one goes where. I think I'll not put a on/off button in now or do i need one? maybe just a switch in the power socket? do i simply connect the pu with the ucd with the submitted 10pin flatcable? where do I connect the audio input and the power from the mains?

Maybe someone has a link to some pictures, I found more stuff about ucd400.

[siamhatter]

somewhere I read I need the softstart module. is this true?

you could be perfectly fine without it,
call/mail hypex support, they are just great people and very helpful
it's been so far amazing support from hypex

Wiring diagrams are on the Hypex website.

Don't mess with mains power if you don't know what you are doing.

[siamhatter]

last question before I order. I plan to order these cases from modu.it: Galaxy Maggiorato GX288 230 x 280 mm. Has anyone experience if the trafo fits in?

[chopstickkk]

Finally taking the plunge I think.

What sort of costs have people been paying for their non-Hypex bits and pieces including enclosure?

Just trying to estimate how much I'll be paying on top of transformer, 2x amps & power supply.

Thanks,
John.

I hope it's the right topic. I plan to update my monitors and am considering all options.

PSI A17M are in the top of my list (and are also the more I can afford), but I've been more than intrigued (and appealed) by everything I've read about Hypex amps (especially the NCore 400) and am also seriously considering this option instead.

I was wondering which (compact) nearfields you'd recommend to use with the NC400 amp ? I'm not afraid to go the DIY route (would quite enjoy building that all actually !).

I like to produce/mix at quiet volume (with occasional check at higher volume), so accurate/honnest monitoring that translate well is what I'm looking for.

Thank you !
