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.

Distinctly different from all other devices, 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 any headphones. 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

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, and coaxial, with charging via a separate Micro USB input.

There are two 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 new completely transparent UHD DSP function.

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. Two 3.5 mm mini-jack headphone outputs allow up to two people to listen simultaneously.

Better battery and charging

Mojo 2 benefits from greatly improved battery management, thanks to a new FPGA-based battery-charging system. The tech brings much faster charging rates, coupled with a huge 75 % reduction in power loss for cooler, more efficient charging. Capacity is up by 9 %, resulting in better efficiency and improved battery life, which is now better than eight hours.

Mojo 2’s established ‘Intelligent Desktop Mode’ technology has also been improved, with an isolated battery and PSU redesign to support battery-free operation without any losses in sound quality, plus improved filtering and isolation. When in desktop mode, the battery is disconnected after trickle charging in order to maximize battery life.

Improved transparency

Mojo 2 is now DC-coupled with a digital DC servo. It benefits from an improved WTA (Watts Transient Aligned) filter, now offering 40,960 taps (the technical indicator of how complex the interpolation filter is), using 40 DSP cores.

Additionally, an improved noise-shaper offers greater depth and detail perception, plus improvements to the 4e Pulse Array DAC introduce lower distortion and out-of-band noise. Greater neutrality has also been achieved, thanks to the elimination of coupling capacitors.
