I'm having a 1200W@4ohm power amp put together. For bass.
A large percentage of the lil Class D bass amps on the market use similar power amp modules.
They're made by ICEPower (unfortunate name, but it's an old company also Danish).
Used be part of Bang & Olufsen.
That's why a lot of those amps are rated at similar set intervals like 500 or 700W.
Anyway, I just figured this out.
I don't use the preamp in my Aguilar Tone Hammer--I use a pedal for that--and...
I can actually make the Tone Hammer's power amp
shut off if I push it a little too hard into 4ohms.
I can do the same thing with the Demeter Minnie I bought.
If I run them
both...splitting the load into 8ohms each...I can get same volume or a little louder, with no overload conditions.
So I thought...
maybe my guy here can make me a power amp out of another ICEPower board...
and that can be my one box, instead of having two boxes, one of which has preamp stuff I do not need.
I got
a 1200AS2, two-channel ICEPower module from Parts Express:
1250W/ch @4ohm when driving ONE channel
670W/ch @4ohm when driving both channels
610W/ch @8ohm when driving both channels
That's at 1kHz, so bonk things down a bit.
But...it's enough, in other words.
I'm having it wired up for (2) speakon outs for each channel and (2) 1/4" inputs.
I can run it mono at a lower overall level on the volume knob...
or in stereo into 8ohm loads that won't be pulling too much current relative to source...
or in stereo into (2) 4ohm loads (four 1x15s) which will probably sound great.
If I do two channels (v likely), I'll use the EA passive splitter that Greg makes.
It rocks and there's almost no insertion loss (Jensen transformer in it).
After spending way too much time looking for enclosures...
I found
a dude in Latvia (!) who has an enclosure kit that he makes specifically for this board.
What are the odds?
People use 'em for home hi-fi and theater, esp subwoofers and shit.
Anyway. Enclosure will be pretty ez to mod (not that I'm doing the work).
The gamble is that there's probably some buffering/filtering going on with what I use now.
I'm positive there is for the Demeter Minnie--it has a deeper, darker sound, and they've done something to juice the output slightly.
So maybe the unfiltered amp will sound different/worse. We'll see.
If it works it'll probably cost less than a new Tone Hammer.
Certainly less than a Tone Hammer and a Demeter Minnie (even used ones like I bought).
And it'll be enough power for any application.
And it will take up less room than using two lil power amps.
And the fan is much larger than the ones in the Tone Hammer and the Minnie--they seem pretty puny for what they have to deal with.
I will write more on here once I get it, probably.
