WM1AM2 Walkman® DAP Music Player

Large solid high polymer capacitor

Adopted as battery assist for the amplifier block, the newly developed large solid high polymer capacitor offers large capacitance and low resistance. Able to instantaneously supply large amounts of power, it can accurately output signals by preventing sudden falls in voltage. This contributes to clear, powerful and accurate bass sound, as well as clear vocals.

FT CAP3 (High polymer capacitor)

Custom-made for Sony and tuned by Sony engineers, FT CAP3 is adopted for all bypass capacitors in the audio block power supply. Drawing on know-how cultivated in high-end home audio development, it has helped to improve sound expression and create a smoother sound, with a wider sound space, more transparency, and tighter bass.

OFC milled block

An OFC milled block covers the digital block, helping both to strengthen digital ground and improve noise shielding from digital block elements such as the application processor and memory devices. The result is a clearer sound that appears to rise up from silence.

High polymer capacitors

The high polymer capacitors within the WM1AM2 are used to strengthen the power supply of the amp block for unbalanced output, enhancing low-range reproduction performance for a more expansive listening experience.

Film capacitors

High quality film capacitors deliver voltage with a linear response across frequencies, resulting in reduced distortion and noise.

Winding inductors

Replacing the conventional laminated capacitor, winding inductors in the digital block power supply contribute to a pure sound.

Oxygen-free copper cable

A low-resistance oxygen-free copper (OFC) cable offers low distortion and superior channel separation.

Crystal oscillators

Two compact low-phase-noise crystal oscillators ensure precision clock stability at sampling rate multiples of 44.1kHz and 48kHz. The crystal electrode piece is formed with gold vapour deposition for enhanced electric characteristics and improved instrumental separation. This helps remove a veil and reduce noise to realise clear, open sound reproduction.

Fine Sound Register

The surface mounted Fine Sound Register ensures even, effective distribution of power to the circuit components, for consistent sound quality.

Newly developed reflow solder containing gold

This is the first time Sony has used reflow solder containing gold, and it features extensively across the circuit board surface – so the overall effect is significant, including improved sound localisation and a wider sound space.

High quality solder containing gold

The exceptional conductivity of gold ensures absolute minimum signal loss. For clearer sound and vocals, a premium, audio-grade lead-free solder with a small amount of gold connects the circuit of the WM1AM2 to the battery.

Low dielectric circuit board and filled via

The printed circuit board uses low dielectric material to realise accurate signal transmission, while the via holes are filled with copper to further reduce impedance. The result is a wide sound space with clear, bright sound. [A] Normal via [B] Filled via

Optimised circuit board layout

By dividing the Audio block (highlighted in red) and the Power/Digital block (in blue), the circuit board layout has been optimised to ensure sound quality is unaffected by digital interference.

DSD Remastering Engine

PCM (Pulse Code Modulation) audio is resampled into an 11.2MHz DSD (Direct Stream Digital) ultra-high-frequency 1-bit audio stream. The single-bit stream delivered to the DAC has a character far closer to that of analogue, giving you even more ways to enjoy your music.

DSEE Ultimate

Using Edge-AI (Artificial Intelligence), DSEE Ultimate™ (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. And the evolving algorithm now delivers even greater benefits for CD-quality (16 bit 44.1/48kHz) lossless codec audio. Restoring acoustic subtleties and dynamic range, it provides a richer, more complete listening experience.

Vinyl Processor

Give the warmth and character of vinyl back to your digital tracks. Enjoy subtle reproduction of the low-frequency resonance, tone-arm resistance and surface noise to deliver an authentic listening experience.

DC Phase Linearizer

Sony's DC Phase Linearizer works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match the phase characteristics of various types of analog amplifier to deliver a purer, more analog-like sound. Choose from six phase character settings.

Every note as the artist intended

Take your digital music collection to another level with High-Resolution Audio. By capturing and reproducing digital audio at a higher rate than CD (24-bit/96kHz and beyond), High-Resolution Audio allows you to get closer to the original studio recording.

11.2 MHz DSD Native / PCM 384kHz

Supreme quality with 11.2MHz DSD native using balanced headphones and PCM 384KHz/32-bit support.

Hi-Res Audio wireless

Enjoy High-Resolution Audio quality without wires thanks to LDAC, Sony's premium wireless codec. With 3x the bitrate of standard BLUETOOTH® technology, you can enjoy a superior listening experience for all your music.

MQA™

The Walkman includes MQA technology, which enables you to play back MQA audio files.

Large 5.0” display

Smooth and responsive, the large 5.0” (12.7cm) touchscreen display has been enlarged from its predecessor’s 4.0” (10.2cm) display and upgraded to HD.

Long battery life

Immerse yourself in your music with up to 40 hours of non-stop 96kHz FLAC High-Resolution Audio playback.

Walkman® Home Screen

With the Walkman® Home Screen, you can customise the home display to suit your needs.

USB Type-C® port

A USB Type-C® port, compatible with USB 3.2 Gen1, offers fast music file transfer and easy connectivity with a range of devices.

Expandable storage

With 256GB integrated memory and an SD card slot, the WM1ZM2 lets you take even the biggest music collections on the go.
