Portable Hi-Res DAC/Headphone Amplifier

Easily connect to your PC or compatible digital music device via USB input to enjoy Hi-Res audio playback with the PHA-2 portable DAC/headphone amplifier. The PHA-2 samples PCM sources at 192kHz/24-bit and DSD sources at 2.8/5.6MHz. The high fidelity DAC, op-amp and headphone amplifier circuits ensure you hear every detail of your music.

Hi_Res Audio DAC and Amplifier

Plug-into your PC, portable digital music player, smartphone, or tablet and enjoy your favorite music tracks including Hi-Res audio files with the PHA-2 portable DAC/headphone amplifier. Compact, yet flexible and powerful, this high-fidelity DAC and headphone amplifier delivers precise output with low noise/distortion for soothing, high-quality sound.

Treat your ears to High-Resolution

Easily experience Hi-Res Audio with the USB DAC and Amplifier that supports the full range of Hi-Res file formats, including PCM audio encoded at 192kHz/24-bit and DSD 2.8 MHz/5.6 MHz audio using any PC or MAC in conjunction with available Hi-Res Audio Player software.

Flexible Connectivity

The PHA-2 supports a wide array of digital devices, with 3 USB inputs: standard A for iPod®/iPhone®/iPad®1 devices, micro-B for PC or Mac®, and mini-B for Hi-Res Walkman® connectivity. The PHA-2 also offers an analog input for connecting to most MP3 players, smartphones and other audio devices in addition to a line out for external amp or active speakers.

High-Quality Circuitry

Specifc, hand-selected components work together to provide sublime audio. The DAC samples PCM audio at 192 kHz/24 bit & DSD audio at either 2.8/5.6 MHz. The operational amp then delivers outstanding signal & performance with ultra-low distortion, low noise & high slew rate. Finally, the high bandwidth headphone amp delivers more than 120 dB of dynamic range to ensure music is heard with every detail.

Jitter-Free Audio Performance

An asynchronous USB 2.0 clock designed to ensure the accurate delivery of D/A conversions supplies a pure clock signal for reduced timing inaccuracies when converting digital signals into analog waveforms. This all adds up to maintains sound stage integrity and audio response, resulting in superior audio performance with minimal noise and distortion.

Powerful Portability

An internal rechargeable battery provides approximately 6.5 hours of hi-res playback when connected digitally via USB input or up to 17 hours of playback when connected using the analog, 1/8" stereo input.2.

Flexible Headphone Support

A two position, side mounted gain switch allows you to optimize the PHA-2's output level to match varying headphone impedances ranging from 8 to 600 Ohm. Select between Low or High settings to maximize your listening experience.

Built for Hard Knocks

A compact aluminum enclosure protects the delicate circuitry from outside interference and impacts while alloy bumpers protect the volume knob and headphone connectors from impact. Recessed control switches also reduce the chance of accidental access during playback.

Supplied Accessories

The PHA-2 comes supplied with two silicone mounting straps, a protective sheet, a stereo mini cable for analog connections, in addition to a micro-B USB cable for PC and Mac® and mini-B for hi-res Walkman® connections. (iPod®/iPhone®/iPad®1 devices must use their own respective cables, not included).
