Product Description
The Revolution is an audio amplifier that separates the signal into individual stereo channels to drive two separate headsets or speakers and images surround sound into 3 channels. The Revolution will provide an 11.5 dB boost with no more than 1% harmonic distortion. No difference in output or frequency response when one headphone or 2 headphones were plugged in at the same time. The Revolution employs similar output amplifiers to those found in CD players. Typical specifications are 20Hz to 20,000Khz +0/-3 dB 33Hz to 20Khz +0/-1dB EIAJ CP-307 Method. Weight - 3 ounces for unit, 6 ounces (170.10G) with 2 AAAA batteries (Energizer E2 or equivalent) Color - High Gloss White FinishReviews
Adds power to your audio playerBefore I plugged in to my iPod, I had the iPod volume at about 75%. With Revolution, the volume is at 30% leaving me with plenty of room to make it louder if needed. Also, due to the volume being lower, the Revolution extends the battery life of the audio device.
Revolution looks like a white rectangle box with nothing but a couple of holes for the jacks and two AAAA batteries (that's not a typo). The package also includes two patch cords: one is three and the other is six inches long. When the jack is plugged in, the LED power indicator light comes on so you know it's in use. It's designed for use with high-end (60 ohm+) headphones. Anything less than that can't handle the Revolution's power.
The technology provides the listener with a surround sound feel, like being in a quality concert hall. The device weighs six ounces and comes in white, black, silver, and black/silver.
To use it, simply plug your headphones into the top of the Revolution. Then take one of the Revolution jacks and plug it into the side of the Revolution with the other end plugged into the audio player. If another person wants to connect, then plug the headphones into the other open jack.
Users who have attempted to share audio find using a splitter sacrifices the sound and quality. Revolution doesn't have this problem as each listener can hear as well as they would if they weren't sharing. Travelers can stop straining to hear portable devices in an airplane, gym, or other noisy setting. The device also adds power to cheaper headphones, but remember the headphones need to be able to handle 60 ohm+.
Its battery door feels fragile - like it could break while I was putting the door back on. But it is unlikely it could be stronger as the purpose of this product is to be as small and lightweight as possible. AAAA batteries are expensive, so this is an added expense. However, every Revolution comes with two batteries to get you started.
Its use is not limited to audio players. It works with DVD players, Windows Mobile devices, PalmOS devices, notebooks, laptops, and satellite radio. The batteries are supposed to last for approximately 24 hours of constant use. The device comes with a 12-month warranty on parts and services.
4 stars on quality
3.5 stars on expense -- if you don't have the required headphones, you have to shell out more.
