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.
500 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.
3
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
40 mW
Output Impedance
This is the output impedance of the headphone amplifier.
1 ohms
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.
USB
Width
The width of the item from left to right (side-to-side) measured in inches.
1"
Height
The height of the item, measured from top to bottom, in inches.
1-1/2"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
6-1/2"

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.

Amplifies as advertised

November 11, 2013

The volume produced out of a laptop is half that of a desktop computer. This product does a very good job of rectifying that situation. I combined the Boosteroo with a Cyber Acoustic CA3602 system for use at my church. The results were all the sound volume I needed with the quality of sound that I needed.

Boostaroo -- Good piece of equip.

September 17, 2013

I have been looking for something to boost the MP3 player output in my truck so the audio would be loud enough to understand. I mainly listen to books. Why, I don't know, but when you run audio out of an MP3 player the audio output is always lower. This product did the trick. It amplifies the audio just enough to get that volume, and not damage the input of your system. I got the one that plugs into a usb jack and bought a usb power unit to plug into the truck. It also has a switch on it to switch between my Sirius radio and the MP3 player. I looked and couldn't find a unit this small to take up the limited space to store it. I couldn't even find something else that would do what this Boostaroo unit would do. I recommend this unit highly.

Reliable since 2000

January 27, 2012

The performance of this small device is iconic, in terms of trouble-free service. I traveled extensively in several countries, and purchased my device in 2000. At this writing, the on-off switch just failed, and the battery life can't be controlled, nor will it connect.

I paid approx. $24.00 back then, and if it cost $50.00 today, Id'e buy another. The amplification of sound is remarkable!
