The Boostaroo Revolution is a unique portable pocket amplifier for personal audio devices and laptops. It will double the volume of any player to headphones (32 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 Boostaroo Revolution is the perfect addition for the audiophile at heart. The Revolution will give your audio an expansive 400% volume increase, while at the same time providing high definition sound. Our patented circuit breaks apart compressed audio signals into three separate audio channels. This effect not only produces a highly defined sound, but creates imaged surround sound as well.

The Revolution works with portable DVD players, MP3 and CD players, satellite radios, PC's, Laptops, and FM transmitters. The Revolution is an audio amplifier that separates the signal into individual stereo channels to drive 2 separate headsets or speakers.

Headphone Amplifier Specifications

Amplifier Style
Some headphone amplifiers are designed to be portable and others are meant to be placed on a desk. This will tell you what style of amplifier this item is.
Portable
Digital-to-Analog Converter (DAC)
A Digital-to-Analog converter (also known as a DAC) converts a digital audio signal into an analog signal. This is especially helpful for listen to music from digital sources, such as iPods and smart phones.
No
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20,000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.3%
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
3.5mm Mini-Jack
Input Impedance
This is the input impedance of the headphone amplifier.
5000 ohms
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
3.5mm Mini-Jack
Number of Outputs
Some headphone amplifiers have a built-in splitter so multiple pairs of headphones can be connected to it. The number specified here is the number of headphones that can be connected to the amplifier.
2
Power Requirement
This is the required way to give the unit power. Common power sources are 120V AC (Common house plugs), batteries, or a combination of the two. If the headphone amplifier uses batteries, this will list the type of batteries that are required. Please refer to the description to find out how many are required for the unit to be properly powered.
AAAA Batteries
Width
The width of the item from left to right (side-to-side) measured in inches.
7/8"
Height
The height of the item, measured from top to bottom, in inches.
7/8"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
4-3/8"

DAC Specifications

Maximum Output Voltage
This is the maximum voltage that the amplifier or preamplifier is able to output.
Output Impedance
This is the amount of impedance that the microphone allows.
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.3%
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
Crosstalk
Crosstalk is defined as the unwanted transfer of signals across communication channels. The higher this number is, in dB, the better crosstalk rejection the DAC is capable of.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
Digital Inputs
The type of digital inputs the digital-to-analog converter features.
Jitter
Jitter is a deviation in or displacement of the pulses in a high-frequency digital signal.
Line Level Outputs
The type of analog line level outputs the DAC features.
Sample Rate
Power Requirement
This is the required way to give the unit power. Common power sources are 120V AC (Common house plugs), batteries, or a combination of the two. If the headphone amplifier uses batteries, this will list the type of batteries that are required. Please refer to the description to find out how many are required for the unit to be properly powered.

Efficient and does what you want

November 2, 2011

I purchased this product in order to boost tahe sound on my iPod when riding my motorcycle. With headphones plugged directly into the iPod I was unable to enjoy music at any speed over 25-30 mph. With the booster in line, now I can listen to clear music sounds at highway speeds with no problem. A great product, reasonably priced.

MONEY WELL SPENT

April 10, 2014

I am a legal/medical transcriptionist and have been dealing with low volume on my computer often making audio dictations hard to hear. I ordered the Boostaroo and had to turn my computer volume down to 1/4. Amazing little gadget, so worth the money. Ordering was quick and easy, and the Boostaroo arrived in two days! Doesn't get much better than this!

Great little amp

February 24, 2014

I bought this product for something a little different, and it works perfect. I was wanting to use a voice modulator for a Darth Vader costume with a throat microphone, however it just wasn't loud enough even with the amplified speaker I was using. When I plugged this amp between the voice mod and my speakers, it worked perfectly and gave plenty of amplification, nice and clear.

Great little sound booster

October 6, 2013

This item has been perfect for my needs, which was to raise output loudness for a home training program. Crisp clear sound without distortion within safe auditory limits. Special battery wasn't hard to find at all.

Boostaroo Inline Aidio Amp

April 14, 2013

I use this on my motorcycle attached to my GPS/satellite radio to kick up the output from the device and split it out to headsets for the front seat driver and back seat passenger. It works as described and we have no complaint. The battery life is quite impressive.
