Chord Mojo 2 (4.4mm) Portable DAC / Headphone Amplifier

Chord Electronics Mojo 2 4.4

updated version (4.4mm + 3.5mm)

Portable DAC/Headphone Amplifier, simply without equal

Mojo 2 is the most advanced portable DAC/headphone amplifier in the world. It plays your favourite music with class-leading detail and clarity, right up to studio-grade levels.

DAC AND HEADPHONE AMPLIFIER IN ONE

The British designed, engineered, and built Mojo 2 is the most advanced portable DAC and headphone amplifier in the world — and it's now even better.

Central to the new version of Mojo 2 is a new 4.4mm headphone output, switchable USB-C charging, plus the world’s first lossless DSP, an advanced ‘digital tone control’ without any degradation in sound quality. The ‘UHD DSP’ gives Mojo 2 unrivalled compatibility with today’s wide-ranging headphones, plus unparalleled flexibility with partnering equipment.

Distinctly different from all other devices, the multiple What Hi-Fi? ‘Best DAC’ and ‘Product of the Year’-winning Mojo 2 uses proprietary British digital audio technology perfected over more than two decades, coupled to a powerful ‘FPGA’ processor. The result is class-leading sound quality both on the move or at home, with the power to effortlessly drive nearly any headphones, now including 4.4 mm variants. For music just as the artist intended, Mojo 2 brings you closer to the music than any other portable.

The Mojo 2 is designed, engineered and handmade in the UK. It benefits from high-grade, bead-blasted aluminium casework, finished with a high-quality black anodization. Control is via four polychromatic polycarbonate control spheres. 

UNIQUE FPGA TECHNOLOGY

For more than 20 years, Chord Electronics has exclusively used powerful programmable (FPGA) circuits with custom coding to provide the most advanced digital-to-analogue conversion performance in the world. With digital audio technologies perfected over two decades, Mojo 2 contains more digital audio know-how than any other small DAC, resulting in unrivalled sound quality, all backed by peerless technical measurements from the lab.

CONNECT AND CONTROL

A further key feature is the new menu system, navigated via the new (fourth) control sphere, bringing mute, crossfeed, button-lock, switchable USB-C charging and tone control adjustment.

Mojo 2 offers several ways to connect to digital devices, including smartphones, tablets, and laptops. Digital inputs include fast-transfer USB-C, Micro USB, optical, coaxial, and dual-data coax.

There are now 4.4mm and 3.5mm headphone outputs, meaning two can listen simultaneously. Mojo's polychromatic light up buttons offer simple control with an additional visual guide to the device's settings. A new menu button offers navigation through a new range of features, including the completely transparent UHD DSP function.

WHAT'S NEW IN MOJO 2

UHD DSP

The new Mojo 2 benefits from several new features, chief of which is a revolutionary lossless DSP, the first of its kind in the world. The innovative new ‘UHD DSP’ is fully transparent, enabling comprehensive tone adjustments across the frequency range, without any degradation in sound quality. The new technology gives Mojo 2 unrivalled compatibility with today’s wide-ranging choice of headphones, regardless of type and sonic signature, plus flexibility with different source components and digital file types.

The proprietary technology uses a 104-bit custom DSP core running at 705/768 kHz: no other audio DSP offers the same accuracy.

The unique UHD DSP enables fine-tuning across the full frequency range with 18 steps of adjustment per frequency banding: lower bass, mid-bass, lower treble and high treble.

 

 

Improved controls

A related key feature is the introduction of a menu system. Navigated via a new (fourth) control sphere, the menu brings a mute function, four-setting crossfeed adjustment, a button-lock feature for travelling, plus the fully lossless tone controls.  

The volume control range has also been improved from +18 dB to -108 dB, and now benefits from two distinct operational ranges: low and high volume. 

A new four-setting crossfeed function, also DSP-controlled, brings speaker-like spatial effects for flexible headphone listening.   

 

 

New USB-C data input

Digital inputs have increased to four, thanks to a new USB-C data input for greater flexibility. USB-C is featured alongside optical, coaxial (incl. dual-data for the M Scaler) and Micro USB. The 3.5mm mini-jack and 4.4mm unbalanced headphone outputs allow up to two people to listen simultaneously.
