Wolverinebass Posted June 23, 2010 Share Posted June 23, 2010 I've been debating this for some time and have finally decided that my rack is too heavy with my Hartke 5500. It's a back breaker. So, I've decided to do the preamp/poweramp route. I was thinking Sansamp RPM, and a poweramp. For various reasons, I want to keep the weight of the poweramp 9kg or less. I know that someone is going to say get a Peavey IPR1600, but I have to have something 1U so it'll fit in my already ludicrously stocked up rack. Now, I've scoured about a bit. I notice Dood recommends Powersoft but they seem to be impossible to find aside from Thomann. The BK electronic looks decent, but I'm wondering about if this is made any more as I read on a previous thread that they are discontinued.

[url="http://www.beglec.com/#product=digit1k0"]http://www.beglec.com/#product=digit1k0[/url] Is it worth getting a sort of middle of the road class D? Such as this? [url="http://www.kam.co.uk/index.php?action=product&product_id=354"]http://www.kam.co.uk/index.php?action=prod...;product_id=354[/url] One thing that puzzles me about this is the specs of the above. Whilst I understand the bridge mode stuff I don't get. Why do double channels at 4 ohms? Do folk think this is a mis-print or have they forgot to put "peak" after it? Still it does look like a fair bit of amp for £300. 2400 watt power amplifier 1200w+1200w @ 4 Ohms 600w RMS+600w RMS @ 4 Ohms 300w RMS+300w RMS @ 8 Ohms 2400w @ 8 Ohms bridge mode 1200w RMS @ 8 Ohms bridge mode Whilst I don't want to go totally mental and twonk £1K on a light power amp, I don't want to get a cheap disco piece of crap. If anyone has any good suggestions or uses something similar I'd be grateful for views if like everything you get what you pay for or is a super light, 1U poweramp in the region of 500W - 800W a myth or cost more money than Lloyds owe the Treasury? Opinions are greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Stewart Posted June 23, 2010 Share Posted June 23, 2010 Bridged mode uses both channels of a stereo amp (into double the per-channel minimum impedance) to roughly double the power. The dual numbers are per channel (stereo) - bridged is mono. Quote Link to comment Share on other sites More sharing options...
Owen Posted June 23, 2010 Share Posted June 23, 2010 Chevin A500 is a lovely piece of kit. It will do 350W per side into 4ohms or bridge 700w into 8ohms mono. Quote Link to comment Share on other sites More sharing options...
ahpook Posted June 23, 2010 Share Posted June 23, 2010 i have a soundtech ps802 (some [url="http://www.proaudiomusic.com/sound_systems/soundtech/PS802_amplifier.htm"]specs[/url] here), i love it...i seem to remember it cost me a few hundred new, but that was a while ago. /shrug/ not sure if that's any help, but if you come across one, it's worth it, although the fans are a bit loud.

Happy Jack Posted June 24, 2010 Share Posted June 24, 2010 I sold my Powersoft (well, Dood's old one) to Flanker a couple of months ago. We were running it through his Epifani cab in his front room. When I switched it on, he assumed it wasn't plugged in. They do make SOME completely silent power amps. Quote Link to comment Share on other sites More sharing options...
