The Portable Amp That Improves The Sound From Digital Sources
Enjoy improved sound from almost any digital source by sending the signal through the PHA-1A. Breathe new life into your collection of audio files and fully appreciate the advantages of High-Resolution Audio. Just plug in and let the PHA-1A do its magic, as you relax and rediscover your music.

Pulse Code Modulation (PCM)
From a PC, iPhone/iPad or Xperia - PCM conversion gives it the best possible sound.

Ultra High Frequencies
Feel sound beyond your natural hearing range, with exceptionally high frequencies of up to 100 kHz.

What is High-Resolution Audio?
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.

Made for High-Resolution Audio
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.

Hear The Difference
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.

Superior Conversion, Purer Sound
A combination of quality components provides superior conversion of the digital source to a pure, high-quality audible signal.

Shut Out The Noise
The aluminum casing of the PHA-1A offers shielding from noise and interference that can adversely affect sound quality.

Small, Light And Durable
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.

Go Lightly
Small and light at about 5.29 ounces for taking around in a bag or pocket.

Carry Easily
A silicone band makes carrying with your Walkman, Xperia or iPhone easy.

Listen For Hours
Play music for up to 6 hours when connected digitally.

Ready To Go
Comes with cables for Apple players, Walkman, a micro standard USB and silicone band.

High-Resolution Audio For Uncompromised Sound
Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bit-rate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artists' music. Savor every breath and subtle movement for a truly emotional experience.

Superior Sound With A Dedicated USB DAC Amp
With a dedicated USB DAC amp connecting your headphones and compatible PC, smartphone or Walkman, you'll enjoy higher-quality streaming of High-Resolution Audio. The amp takes over responsibility from your portable device for processing and converting digital data, then amplifies sound using its own integrated amplifier.

PCM Support For Pure Quality
Get close to the original source. Supporting data volume that's about 6.5-times that of CD (44.1 kHz/16 bit), PCM (Pulse Code Modulation) handles up to 192 kHz/24 bit for a sampling rate and bit depth capable of reproducing wave characteristics that are very close to the original analog wave. In addition to providing clear reproduction of high frequencies, PCM also enables subtle nuances and resonance to be expressed with high fidelity.

Wide Frequency Response For Ultra Clear Harmonics
The wideband frequency range-spanning 10 Hz to 100 kHz is designed for today's broad variety of music styles. At the 100 kHz high end, you'll be able to enjoy vocal melodies, subtle audio harmonics and tonality in outstanding clarity, as well as feel sound beyond your natural hearing. This is especially relevant with High-Resolution Audio, which unlike CD and MP3 music, supports high frequencies up to 100 kHz for a more realistic, emotive sound.

High-Quality Dedicated Digital-To-Analog Converter (DAC)
Digital-to-analog conversion is required by any audio device to convert digital data (such as music files) into an analog signal (to drive headphones or speakers). However, all DACs are not the same. Many portable devices incorporate DACs based on whether they fit within space and other limitations, but the PHA-1A is a dedicated device consisting of a high-performance DAC and amplifiers with the sole purpose of handling audio. That's why listening through the PHA-1A provides an audio experience that far surpasses listening through the built-in DAC of a smartphone, iPhone/iPod or PC.

High-Quality Components For Pure Sound
The digital source is converted to a pure, high-quality audible with a 192 kHz/24 bit capable DAC (WM8790), low-distortion low-noise operation amplifier (LME49860), high-power output high-fidelity headphone amplifier (TPA6120) and OCL amplifier output stage using two power supply methods.

Portable, Lightweight Design With Durability
Small and light at about 5.29 ounces the PHA-1A has a rugged aluminum case to protect it from everyday knocks and shocks. Rounded edges make it easy to hold when out and about. Comes with a silicone band for comfortable carrying along with your Walkman, Xperia or iPhone.

Record at a Higher Frequency than CD
High-Resolution Audio typically records at 96 kHz/24 bit or even 192 kHz/24 bit.

Hear More Realistic, Emotive Sound
High-Resolution Audio supports frequencies above 24 kHz - way beyond CD quality.
