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.
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).
10 - 100000 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.
<0.009%
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.
16-300 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
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
150Mw mW
Output Impedance
This is the output impedance of the headphone amplifier.
16-300 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

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.
<0.009%
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.

Works as advertised! Been using it for 6 months and I love it. Really drives the sound for my Bose QC15 headset. Base amplification is very good. The highest bass setting is too much for the Bose QC15 but just turning that down works. Plenty of bass reserve for those headsets that can handle it. Enhances the sound quite a bit. Does a great job as a DAC. Battery life is great too. A great investment in sound!

I am new at this , but I assume this unit is not to be used with a portable CD PLAYER, but only with a computer?
A shopper on Aug 5, 2014
Best Answer: Hello,

We aren't sure we understand your question/inquiry.

The Encore E7 has absolutely no relationship with anything having to do with CD Players, and does not require a computer for any of its immediate uses.
