4 ohm watts and 8 ohm watts
 

I've found a forthcoming power amplifier that I may be interested in, but
the only specs available at present are that it does 500W into 8 ohms
bridged for mono, and 230W per channel into 4 ohms.

What would be its likely stereo output into 8 ohms?

Those numbers don't quite stack up, but you will get something like
120W per channel - perhaps a bit more.

It should be 125W per chan - and 230W into 4R indicates that it
propably has a good power supply as well. What it does not show
however is the conditions under which the power measurements were
taken, or the current driving capability of the outputs, so one
channel into 8R might actually do rather more than 125W.

Likely to be about 130 watts/channel into 8 ohms, but that alone
doesn't make it a good amplifier...................

Didn't say it did. :-)

It's another Behringer jobbie. Although I have little to go on, other than
other people's opinions of their kit, and my experience of the active
crossover, I'm gravitating towards the idea that their stuff might just be
rather good.

No techy specs as yet, but here's the spiel from their web site (note that
it isn't available yet, so this is essentially marketing blurb)...

---------------------------------------------------
Professional 500-Watt Reference-Class Studio Power Amplifier

This ultra-linear power amplifier is the top choice for recording studios
and post-production work, yet its amazing price is just the beginning. You
get true audiophile-grade performance that delivers 2 x 230 Watts into 4
Ohms or 500 Watts into 8 Ohms bridged, with enough overhead to always keep
you on the safe side. The A500's advanced convection-type cooling system
guarantees stable, noise-free operation, while its servo-controlled design
can drive virtually all passive speakers. A precise level meter and clip
indicators are provided for accurate performance monitoring. Input
connections are laid out on balanced XLR, 1/4'' TRS and RCA connectors,
making sure you never run out of connectivity options. Plus, the speaker
outputs give you a choice between professional ''touch-proof'' binding posts
and 1/4'' TS connectors. To assure years of trouble-free operation, we only
use the ultra-reliable Toshiba® or Fairchild® high-power transistors that
are known for their rock-solid reputation. In addition to all these
features, an independent thermal overload protection system with LED
indicators for each channel automatically protects both your amplifier and
your speakers. Last but not least, we have relied on a tough high-current
toroidal transformer for absolute reliability and lowest noise interference
possible.

You and your clients deserve the very best in studio power amplification.
Get the A500 and it will be love at first sight: it is super affordable,
super effective and super flexible!

Sounds fine to me.

The blurb says it as a 'high current' toroidal transformer.

taken, or the current driving capability of the outputs, so one
channel into 8R might actually do rather more than 125W.

I think that sort of power is probably well beyond what I need, which, I
suspect, is a good thing. I'll reserve judgement until the tech specs
appear, however.

An odd spec, since 230w/channel into 4 ohms should equate to 460 watts
bridged into 8 ohms, not 500 watts. The absence of a fan is a plus for
home use, but note that pro amps are often run at much higher average
levels than you'll use at home, so you really do need to check that
this unit sounds good at a watt or so, which is a typical home average
level. Pro amps, while they *can* sound good, are designed with cool
running and reliability as first priorities, not sheer sound quality.

Despite some 'knocking copy' you may have heard from the so-called
'subjectivists' on this subject, it's not actually true that *all*
amplifiers sound the same! :-)

It's reasonable value for money. Let's leave it at that. ;-)

Aye. Maybe they've bumped up the 8 ohm bridged performance to get a nice
round number for the model name.

Yup. I'll be interested to see what its s/n spec is.

Maybe so, but how far downwards can the quality go, if they are to get away
with calling it a 'reference class studio monitor'? The other two power amps
in their range (more powerful) aren't described the same - I get the
impression that they're more like live sound reinforcement amps, so I doubt
if this new one is going to be a pishy, buttered-up PA blast-box.

I can happily take that stuff with a half pound tub of Saxa... :-)
