Bet some dude could paint it to look like R2D2 to go with his modded case with the blue lights and Star Wars stickers...

Run from this deal. There is no way that this thing is 30w. Then again, it's only $20 so it wouldn't be a huge mistake. Just a mistake.

Looks like the old Soundbite amplifier. They use to sell these things at CC...kind of an add-on speaker system for portable cd/mp3 players. If it is the same, they sold for around $50.00 several years ago.

RadioactiveMagpies -- This thing appears to be a power amplifier designed to drive speakers directly. You would not want to put it between the output from your sound card and powered speakers having built in amps.

I wouldn't buy any amp like this without knowing more about its real specs. The 30 watts spec can mean almost anything from a valid RMS rating at low distortion to how much power it draws from the power mains at 100% distortion. It is not a good deal unless you know exactly what it is.

It may be 30 watts IPP (Imaginary Peak Power). If it walks like a turkey and looks like a turkey ...

Just the thing to power your Wilson Audio Grand SLAMM!

This is probably very equivalent to the built in amplifier in a $7 pair of amplified speakers.

Another store here has them as well along with some comments on the unit. The 30W (15x2) is probably peak (PMPO) rather than real (RMS) power. A rough rule of thumb is divide PMPO by 2 to get RMS. This isn't alot of power, especially with cheap inefficient speakers.

Ok peeps this is a word to your mother, it certainly can be 15w RMS power. Think about it, even the amps in your computer speakers are most of the time rated at RMS, unless you cheaped out large like. Kids do some math, $20 for 15w X 2 amp, and oh say $20 for a pair of speakers and you have your average computer speaker set up. And do you even know what the difference in volume out put is say from going to 7.5w to 15w is? No? Ok I'll tell you and your mother, its 3 freaking dB's, 3!!! WOOH-HOOOH! Anyways, stop arguing about the amp and pass on it; or buy it so you can run a small pair of speakers in the garage/shop while you work, trust me you won't be sitting there pounding on your car or drilling a large hole in your new computer case and saying to yourself is that RMS watts I am hearing or something else. It will be loud and good enough for your needs. Heck its good enuff for that bedroom speaker setup you always ment to get around to doing. Dang peeps worry to much about nothing......

Oh looky here, it is RMS.

That thing cannot put out a constant 30w. Here is an old post regarding the myth of amplifier output:

Its refering to a pair of Logitech computer speakers.

"Some of you seem confused about power measurement. PMPO stands for complete power lie basically. Peak power stands for 2 times RMS power. RMS power stands for an accurate power measurement at one moment in time. The RMS value is meaningless without a time constant. Perhaps the amplifier can truly output 400w RMS, but for only .2 seconds. See, no one is lying. Another fun factor is that they will rate the power at an easy frequency such as 1khz. So, a good power rating on an amplifier would be this: 400w RMS into all 4 channels at 4ohms, driven from 20hz - 20khz +\- .5dB with less than 1 percent total harmonic distortion, driven with a constant white noise input signal for 1 hour. I dont think a manufacturer can fudge anything in there! Also the power transformer needed for 400w operation is about 7-800va. That is way too big to fit in that little box. Also, the amplifier's heat sink is too small to disapate 400w RMS for very long. Not to mention the speakers could not disapate that kind of power for very long.

Power ratings can be a very deceptive thing. "

The Powerbite personal stereo amplifier provides 30 Watts (15 x 2) of audio power to boost the output of your computer, portable CD player, portable TV or video game. Provides a clean, full sound that can be played through bookshelf or larger speakers. This ergonomically designed desktop amplifier has a trackball-like volume control, tone control and LED power indicators. Includes hook-up cable (3.5 stereo to RCA plugs) and power supply. Attractive retail packaging. Speakers not included.

Note: When we sold this unit last year (as CAT #PBA-30) and received comments like, "works great, but it runs hot." We decided to see what we could do about the heat problem and found that, even though the manufacturer recommends a 15 Vac wall transformer for power, it works just as well on 10 Vac and runs a lot cooler. So we've switched the 15 Volt transformer for a 10 Volt transformer and, just to make the deal a little sweeter, we've lowered the price.
