Silverstone Shows Off an USB Powered Audio Amplifier

post #1 of 10
Thread Starter 


First one of its kind Power speakers directly with the Silverstone EB03

Quote:
Silverstone demonstrated a prototype USB audio amplifier, the EB03, at Computex 2007. The Silverstone EB03 pops into an internal expansion slot and draws power from a four-pin floppy power connector. The audio device interfaces with the system via USB, connecting to an internal USB header.

The Silverstone EB03 takes advantage of an ESMT Class-D digital audio amplifier with USB interface to power speakers. PC audio is piped to connected speakers directly in digital form with digital amplification technology, negating the use of digital-to-analog convertors. Users can connect any unpowered bookshelf and floor standing speakers to the Silverstone EB03 without a separate receiver or audio amplifier.

Silverstone claims the EB03 can output 35-watts of power per channel with a signal-to-noise ratio in excess of 105dB. Silverstone did not reveal the total harmonic distortion levels, however.

The Silverstone EB03 features two RCA audio output connectors instead of speaker terminals. Silverstone is undecided on whether to include RCA-to-stripped end cables for speaker terminal connectivity with the final shipping product.

The Silverstone EB03 is still in development, but the price can be as low as $50 when the product ships, Silverstone representative Tony Ou said.

Not first of it's kind. The Alien DAC is USB powered and has line level outputs just like that has. Or the HPDAC has an Alien DAC and Pint class headphone amp that is fully USB powered in one box. The silverstone solution needs additional power and I doubt sounds as good.

I don't know why they would make the terminals RCA jacks. The only speakers that use RCA suck to the max.

This kind of product just seems kind of pointless to me anyway...

RCA has two leads...+ and -. You can strip them and wire them straight up to the bare lead speakers...

I know, but why not just have regular speaker terminals or banana plugs?

no, you can get some really good powered monitors that will blow away other 'computer' speakers

umm... please don't tell me you're serious! line level output and speaker level output are fundamentally different. The product described will NOT power speakers. You have to use the line level output and feed it to a speaker amp

What? I thought this was an amp with RCA out for speakers? I'm kind of confused now. Why does it say amplifier if those are line level outs?

The title is confusing seeing as it's not powered by USB.

hmm... well it does say that it can directly power speakers... but it doesn't have normal speaker terminals. Maybe it comes with a box?
