"It's Krud-Sonik -- so you know it's great!"

[William Sommerwerck]

I keep seeing "Technical Pro" products advertised, especially in "close-out"
catalogs. The spec'd power ratings (how does one get 400W peak out of a 45W
amplifier?) are beyond my understanding of basic physics.

The claim that, if you know pro audio, you know just how great Technical Pro
is, sounds as if it were written by someone at Bose.

Who, exactly, is "Technical Pro"?

Just curious...

You just don't get it for very long. That's not unusual
performance for a 45 watt amplifier, but it's not usually
sold as a 400 watt amplifier.

Where do you see this advertised? Is it a brand name? Or a
description?

Forgive me. In my rush to post, I neglected to include a URL

JR is not the only company selling this "brand". I'm rather disappointed
that it does, though.

You're assuming 8ohm speakers which NO cheap amplifier manufacturer does
when claiming PMPO, even IF his amp cannot handle 4 ohm speakers for more
than a few mS before blowing up.

Exactly.

Shades of Music Power!

It would have to be a very poorly regulated power supply.

ROTFLMAO.

I met one of those guys some years ago. When I told him what I owned and how
much it cost, he got very angry. "You could buy a car for that!"

The reason it says "Professional" is that if it were a consumer
product, that sort of advertising would not be allowed.

I recently bought a piece of gear that was sold as having 50 watt
output. It was powered by a wall wart of 15 Volts, 1.6 Amps
capibility.

With 100% efficiency, that comes to 24 watts, but it was adequate for
the purpose. I only needed about 5 watts and it sounded fine for that.
