Small form factor power amps

There is a company called powersoft, you can find them sold on Invalid Link Removed they sell high powered, light weight, single space power amps....

Acoustic Image used to make a the Focus SA which was the power amp section of what is now the clarus + (1000w @2 ohms, 800w @4 ohms, 500w @8 ohms) It didn't seem to sell all that well.

For bass players who use a seperate pre/power section I don't know that there is a big market for micros, by their nature they seem to be at opposite ends of the spectrum.

No reason you can't buy a micro head and bypass the preamp section by utilizing the return/power amp in on the effects loop.

Wow! Spooky! I was just typing a thread about Powersoft over on BassChat!

Thus, I will repeat it here : They are stunningly good power amplifiers. It was a 1u 1KW RMS+1KW RMS power amplifier and is the best quality stand alone power amplifier I have ever owned. A seriously nice piece of kit with gobs and gobs of clean, powerful output. PA Engineers love them for their ability to perform with Subs (as I have read on PA forums).
 
Being so small, they probably wouldnt upset the TS specs of the cab either.

Let's not get too carried away on the koolaid drinking. There's enough internal volume there that it needs to be accounted for during the enclosure design and tuning stage, or when retrofitting if you want the performance not to suffer too much. It wouldn't be an issue if more cab makers were designing enclosures in the middle or far end of what their drivers work well in, but most of them are cramming things as it is.
 
Cheers Dood! Yeah, it is a wee beast. My current plan (such as it is :rolleyes: ) is to build some BFM Jack 10s and stick it in the back of one of them. Still pretty much vapourware at the moment.

Sweeet! Do it! Do it!! I kept wanting to do something similar in an effort to get an active cabinet together - even toyed with an idea that someone mentioned about slotting an amplifer into Alex Claber's cabs (Having been away from TB for so long I hadn't seen some of the Fearful builds coming along ether) - However having stumpled upon ISP Technologies on the net, any plans to 'do it yourself' were no longer necessary.. I left it to the professionals!

- Will you build one active cab and daisy chain a passive cab off it? That could work nicely!

Hey Greenboy! A point well made - ok, I was being a bit optimistic!

That would be the idea. I haven't looked at the Jack plans yet (although I have the Omni 10 plans) but my long term plan would be a 2x10 and 2 1x10s, and make one of the 1x10s active and daisychain the others from that, since the amp is safe to 2 ohms. Can't imagine needing more than that!
 
Amp came in yesterday and I just hooked it up to one PA top and two subs. (I have BFM Omni 10.5s and Tuba 24s and the tops are SO much more efficient, I've found that without some signal processing in front of them the subs just get trounced on so both subs balance more closely with one top.) Anyway, I hooked up an mp3 player to the amp: one channel through a small 7-band eq pedal, the other straight in (eq'd the top and dropped level a bit, full range to the subs). Power seems pretty good. The amp has a 100w/300w/500w switch that definitely changes power level. I have another small eq that I'll play around with tonight if I get time to pseudo-crossover the sub and get a bit more low end going (another thing normally handled through DSP in my setup, but processing is built into my amp so no way to just wire it through this little beast).

Initial impressions are that it might be a little thin on bottom end (again, more testing to follow), it's a little heavier than I was expecting, but not really heavy by any means (I don't have any kind of scale at all, so don't even ask), sounds nice and clean with no self noise that I can really find, every kind of input I could think to put on an amplifier except 3.5mm, speakon outs! I won't get a chance to try it with a bass cab until next week (mine's at church), just so you know.

That's about it for now. I'll try to get more up and maybe a pic with a DVD case or something for some kind of reference in the next day or so.

FYI, I bought this as a possibility to power an uber-portable PA setup for my wife's karaoke rig. The real setup is the above mentioned BFM cabs, two gator mixer-top racks (8ru audio, 6ru video), 17" LCD singer monitor, two vocal monitors, laptop, table, chairs, bin of 15-20 binders with song lists, huge bin of audio, video & power cabling, lighting rig, lots of mics, stands for everything, etc. It fills the entire bed of my Tundra and the back seat.

I'm trying to put together something she can fly with: bigger pelican/SKB case with a small mixer, hopefully this amp, a pair of small speakers (probably the biggest challenge in this packaging), mics, cables, POSSIBLY a secondary computer monitor for the singer, lightweight folding mic stand, couple of songbooks. Laptop lives in a normal laptop bag separate from this box.
