Freddie75 Posted January 16, 2015 Share Posted January 16, 2015 Anyone have any experience using 1u poweramps and can recommend something? I'm looking to pair up with a trace v-type preamp. Equally if you are thinking of selling sonething then let me know. Cab I'm using is 700 watts / 4ohms so need something quite powerful. Many thanks in advance!

discreet Posted January 16, 2015 Share Posted January 16, 2015 (edited) I've used a W-Audio Horizon 1U power amp in the past and it was good. This one will mono bridge at 1100W @ 8ohms and do 2 X 550W @ 4ohms: [url="http://www.djsuperstore.co.uk/W-Audio-Horizon-1100-Amplifier"]http://www.djsuperst...-1100-Amplifier[/url] Edited January 16, 2015 by discreet Quote Link to comment Share on other sites More sharing options...
mazdah Posted January 16, 2015 Share Posted January 16, 2015 The powerful ones are expensive, I was going to buy Behringer Europower, but I found Ampeg B1 head (150w @ 4 ohms). Enough power and AMAZING sound when I don't want to use my preamps. Quote Link to comment Share on other sites More sharing options...
Graham Posted January 16, 2015 Share Posted January 16, 2015 Matrix make a 1u Power amp, supposed to be quite popular with guitarists who use AxeFx/Kemper modellers - so presumably quite a flat sound Quote Link to comment Share on other sites More sharing options...
Dood Posted January 16, 2015 Share Posted January 16, 2015 if your pockets are deep, then Powersoft offer some truly amazing amplifiers with a range of truly astounding power outputs. your other alternative is to trawl the for sale ads for either a Markbass F1 or F500 or Galien Krueger MB head such as the 500 or 800 - all of which are 1u heads with rack mounting kits and you can set them reasonably flat (or in the case of the GK heads, plug straight in to the effects return. A cheap way to a 1u power amp - you also have extra tone options should you use the preamp on those heads too! Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted January 16, 2015 Share Posted January 16, 2015 Have you looked in Maplin? I suggest you don't! Quote Link to comment Share on other sites More sharing options...
Ghost_Bass Posted January 16, 2015 Share Posted January 16, 2015 Check out the classifieds, i'm selling my rack and i'm willing to split so if you want a 1kW amp that'll go down to 2ohms in stereo and 4ohms in bridge let me know.

vailbass Posted January 18, 2015 Share Posted January 18, 2015 I can recommend the [url="http://artproaudio.com/art_products/studio_amplifiers/product/sla2/"]ART SLA-2 amp [/url] I've been using that for my around town gigs with a single 15" EVM 15BX speaker and Ashly preamp (circa 1980) very clean and punchy; sounds SO much better than the cheap Class D stuff though this amp isn't light if that matters to you, (~20 lbs.)

Pentode Posted January 18, 2015 Share Posted January 18, 2015 A common question here Freddie, does it have to be 1U? If you can go up a space it'll open up your choices and 2U amps can sometimes be quite a bit shallower too. Quote Link to comment Share on other sites More sharing options...

Freddie75 Posted January 18, 2015 Author Share Posted January 18, 2015 Thanks for all replies guys - much appreciated! Ideally 1u as planning to pop it into a 2u rack case along with preamp. Power wise, I'd prefer to have the headroom rather than be pushing it all the time and would like to have enough power (should I ever need it) to get the best of the cab I have which is a berg cn212.

fretmeister Posted January 18, 2015 Share Posted January 18, 2015 Demeter do a narrow 1u mono power amp - it is NOT rack mountable in its tiny form, but if you are buying new direct from them they will put the amp into a standard rack housing instead, for at extra $50 It's 800w Quote Link to comment Share on other sites More sharing options...

[/quote] Yes, but they're particularly problematic in 1U amps. They're so small that they have to run much faster to pump enough air. Not sure what the replacement options are in this case.

Guest bassman7755 Posted May 17, 2015 Share Posted May 17, 2015 Some of the puma amps are 1U with suitable rack ears, you could go into the line in, expensive but stupidly powerful and light and the option of using it standalone for emergencies.

Tweedledum Posted May 18, 2015 Share Posted May 18, 2015 SYNQ comes to mind: http://www.musicstore.de/en_EN/GBP/Synq-Audio-Digit-2K2-Endstufe-2x-1100-Watt-/-4-Ohm/art-PAH0008521-000 Quote Link to comment Share on other sites More sharing options...
aledeville Posted May 23, 2015 Share Posted May 23, 2015 (edited) The Synq's are really good! Very quick and precise. I had the Crest 8200 before the Synq 3k6 and this is some difference for sure. For normal use the 1k0 is fine and delivers very much for not that much money. The 2k2 is really tough, but I was able to get the 3k6 for the price of the 2k2 (they were not in stock). So I got that going... which is fine with me Nothing can compete with these amps without making huge limitations in some points. These things are light, loud, precise and comparatively reasonably priced. Edited May 23, 2015 by aledeville Quote Link to comment Share on other sites More sharing options...

If you tske the best Clasd D amp it will be approx 93% efficient and a SMPS will be around 90%. So your amp will be generating approx 700 watts of heat Even with multiple fans and the biggest heat sink it would be hard to keep that cool, Quote Link to comment Share on other sites More sharing options...

I suppose some do, but in 'normal' use, the 'real' power would, I suspect, be far less than that. Not saying that such an amp couldn't run hot, but it would be in rather special circumstances, I'd say. Putting out a 'clean' 200w (say...) and leaving the rest as transient 'headroom' could be a good deal, could it not..? Quote Link to comment Share on other sites More sharing options...
