USB DAC Headphone Amplifier
High-Resolution Audio refers to a collection of digital processes allowing the encoding and playback of music using higher sampling rates than those used in CDs.
High-Resolution Audio typically records at 96 kHz/24 bit or even 192 kHz/24 bit.
High-Resolution Audio supports frequencies above 24 kHz — way beyond CD quality
For a quality High-Resolution Audio experience, the PHA-1A supports asynchronous transfer to reduce noise and allows even 192 kHz/24 bit content to be enjoyed fully.
The PHA-1A offers an audio experience beyond what's usually possible with the built-in digital-to-analog converter in a smartphone, iPhone/iPod, or PC.
A combination of quality components provides superior conversion of the digital source to a pure, high-quality audible signal.
The aluminum casing of the PHA-1A offers shielding from noise and interference that can adversely affect sound quality.
Be ready for anywhere with a compact, lightweight design that won’t weigh you down. Its rugged aluminum case protects from everyday knocks and shocks.
