mp2031 Posted April 26, 2009 Share Posted April 26, 2009 Hey guys , I've been seeing these around a fair bit on ebay. Has anyone tried one of these out or anything from the Biema W range ?? ebay link : http://cgi.ebay.com.au/BRANDNEW-BIEMA-350W...%3A1|240%3A1318 thanks Miles Link to comment Share on other sites More sharing options...
leven Posted April 26, 2009 Share Posted April 26, 2009 (edited) Hi Miles, I had that exact amp and used it to drive a dual voice coil Shiva sub that I built. I used a channel per voice coil. It was brilliant with heaps of grunt. It ran cool and was quiet as well. The worst thing was the bright blue LED on the front panel at night, which I put some tape on to cover it! I sold the sub/amp setup to a guy on this forum who seems happy with it. Altronics here in Perth sells them but not that cheap.

myrantz Posted April 26, 2009 Share Posted April 26, 2009 I sold the sub/amp setup to a guy on this forum who seems happy with it. That would be me.. No complaints so far, but I'm very easy to please ... I do have to turn it on/off manually though.. Link to comment Share on other sites More sharing options...

tb1231503560936 Posted April 26, 2009 Share Posted April 26, 2009 (edited) Not sure if it's exactly the same thing, but there was a thread on Pro Amps HERE a while ago Edited April 26, 2009 by tb123 Link to comment Share on other sites More sharing options...
myrantz Posted April 26, 2009 Share Posted April 26, 2009 Not sure if it's exactly the same thing, but there was a thread on Pro Amps HERE a while ago Yar, it is.. Nice find.. Mitcon is using the 330 II I think (more powerful than the 220 II)... This DIY 12V trigger from the thread... Is it legal? Interesting, might be googling up info for doing this...

Is it legal? Interesting, might be googling up info for doing this... I know Mitcon is enjoying his with his new speakers. Not sure about the 12V trigger. I looked at it briefly and although I dont mind doing a bit of DIY on low voltage stuff, tend to stay away from 240V etc. The potential consequences are too high if something goes wrong.

myrantz Posted April 26, 2009 Share Posted April 26, 2009 I know Mitcon is enjoying his with his new speakers. Cool.. Honestly did not expect that. Can't really try it myself coz no large speakers to play with. Not sure about the 12V trigger. I looked at it briefly and although I dont mind doing a bit of DIY on low voltage stuff, tend to stay away from 240V etc. The potential consequences are too high if something goes wrong. It's only 12V.. Just yesterday I saw something in Bunnings - a switch that can be turn on/off by IR. Costs $30-$40 bucks I think.. Might get that instead if it allow discrete codes for on/off... Standby for that switch is 0.25W.. However standby for that 12V trigger thingie if not wrong is 0W.. But as you said, the consequences are too high...

Autocrat Posted April 26, 2009 Share Posted April 26, 2009 Sometimes specs really do tell you something. Or, they should tell you something. For example: * Power output measurements aren't much use without the frequency range they were measured over and the THD measured at that output. * A signal to noise ratio quoted at "> 90db" does not inspire confidence. By way of comparison, an Elektra theatron has an SNR quoted at 124db. The difference is astronomical (although the Elektra is more than twice the price per channel). Or, to put it another way, these amps are noisy. The appear to be well constructed and robust (all pro amps should be). Good for PA, good for studio monitors, good for open air concerts if you have a big enough stack of them, probably good enough for an HT sub. But these are not HiFi amps, one of the reasons they are relatively cheap. Link to comment Share on other sites More sharing options...
Jeffie1503561482 Posted April 27, 2009 Share Posted April 27, 2009 If they are so noisy why would they be OK for studio monitors? Link to comment Share on other sites More sharing options...
joz Posted April 27, 2009 Share Posted April 27, 2009 (edited) I can't personally comment on these amps but.. Like all other amps, not all pro amps are built the same either. Not sure whether they noisey or they have a higher than normal noise floor which would be two things that would annoy me.

Autocrat Posted April 27, 2009 Share Posted April 27, 2009 Because SNR isn't all that important for that application. Power without clipping is. Mind you, if these things have fans they'd be useless. Link to comment Share on other sites More sharing options...
myrantz Posted April 27, 2009 Share Posted April 27, 2009 Because SNR isn't all that important for that application. Power without clipping is. Mind you, if these things have fans they'd be useless. I don't think I ever hear the fans (if it's ever on)... Been feeding the amp 150hz and below, it handles that well - seems to have an endless supply of juice. If all you want is power, it's certainly there.. No idea about clarity in full range, but for <150hz, I'm happy with it... Link to comment Share on other sites More sharing options...
