This Revolution model has been upgraded with a AC power supply for use in a home or office. No more batteries are required for this pocket-sized audio amplifier. The Revolution is an audio amplifier for wired and wireless headphones that provides 400% increase in volume to help you hear your audio with more clarity. The Revolution will work with a variety of audio devices such as television, home stereos, personal computers, speech transcription. The amplifier also has a built-in 2 channel audio splitter that lets you share music and movies.

The Boostaroo Revolution will amplify the audio signal coming from your audio player up to 400%. This extra power provides the boost needed to adequately amplify the signal coming from a TV or PC to your headphones or PC speakers. The added power increase also allows your to lower the volume of your device, resulting in decreased distortion and noise.

The Revolution has a patent pending audio cross feed circuit that increases the dynamic range of audio, providing the user with a clear audio and a more natural listen experience. Many users compare it to a sense of being in a recording studio. For those that suffer from hearing loss (and you use wireless headphones to watch TV), the Revolution is a must own accessory. The added volume increases and enhances the audio clarity, while allowing you to adequately hearing your television shows without disturbing others.

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.
Desktop
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.
0.5%
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.
120V AC
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.
0.5%
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.

exactly what I hoped for!

December 6, 2013

Bought a new tv for my father - he's super hard of hearing so I also purchased Solo Beats by Dre for him. Plugged them into the tv & I could barely hear anything! Looked online for something to increase the volume & found Boostaroo Revolution R234-TV. Plugged it in & it works like a dream! Exactly what I was looking for. Fingers crossed it works forever :) today is only day 1 with it, and so far so good!
