Headphone Amplifier Specifications

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.
Built-in
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.
0.00045%
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
Coaxial and Optical
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
1/4" Plug
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.
1
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
795 mW
Output Impedance
This is the output impedance of the headphone amplifier.
3 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.
110 / 220V AC
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.

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.
0.00045%
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).
20 - 20,000 Hz
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.
106 dB
Digital Inputs
The type of digital inputs the digital-to-analog converter features.
S/PDIF Optical (TOSLINK)
Line Level Outputs
The type of analog line level outputs the DAC features.
Pair of RCA Outputs
Sample Rate
16-32-bit at 44.1-384 kHz
