The Boostaroo Revolution is a unique portable pocket amplifier for personal audio devices and laptops. It will quadruple the volume of any player to headphones (60 ohm or higher) and provide 3-D surround-sound imaging. If you're picky about your sound, the Revolution is tailor-made for your listening pleasure!

The Revolution separates the audio signal into individual stereo channels to drive two separate headsets or speakers, and images surround sound into 3 channels. Depending on the ohm rating of headphones, the Revolution will provide an 11.5 dB boost with no more than 1% harmonic distortion.

No difference in output or frequency response was observed when one headphone was plugged in or when 2 headphones were plugged in at the same time. *

The input impedance was found to be approximately 500 ohms. The output impedance was approximately 1 ohm. Maximum power transfers occur with a 16 ohm load.

Frequency Response: The Revolution employs similar output amplifiers to those found in CD players. Frequency response is equal to or exceeds specifications. Typical specifications are 20Hz to 20,000Khz +0/-3 dB 33Hz to 20Khz +0/-1dB (EIAJ CP-307 Method).

Output:
Up to 32 mW per channel, 2 channels driven
Distortion normally less than 1% with reasonable quality headphones.

Input:
Impedance 5K ohms@1Khz
2.6 volt (RMS) max input for no more than 1% distortion

Input/Output:
11 - 11.5dB boost from CD player (acoustic)
Voltage gain: 11.5 dB boost

Power Requirements: VDC minimum: Cutoff may be considered as 0.8 volts per cell. Two AAAA cells are required. Use of alkaline batteries is suggested for longer playing time. Also works with rechargeable batteries; nickel-metal hydride type preferred. Battery life estimated at 20 hours, depending on headphone impedance and sound level. Input must be unplugged when not in use to conserve battery life.
