Sony NW-WM1AM2 Portable Audio Player

WM1AM2

An evolution in pure listening pleasure

Lose yourself in high quality sound that’s even more dynamic and transparent, with a richer, more expansive sound field. Coupled with the ease of downloading and streaming music, it takes your listening enjoyment to a whole new level.

An even stronger power supply
The WM1AM2 boasts an even stronger power supply than its predecessor, not only in the analog block but also in the digital block – an idea inspired by our flagship digital music player, the DMP-Z1.

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.

Extraordinary sound begins with exceptional components
In our quest to achieve the best possible sound quality on the WM1AM2, we’ve upgraded a number of components. We’ve also worked tirelessly to optimise the layout of the various parts – another crucial factor in realising high quality 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.

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.

Advanced sound processing
The WM1AM2 features a range of sound processing technologies to help you get the most out of your music, whatever the source.

Wi-Fi lets you stream and download even more music
Supported by Android™ and compatible with Wi-Fi, the WM1AM2 gives you even more freedom to enjoy music. Listen to your favourite streaming and music apps on your Walkman or connect to a PC to download tracks and playlists from your music collection.
