Mojo 2 Portable Headphone Amp/DAC

The British-designed, engineered, and built Mojo 2 is a highly advanced portable digital-to-analogue converter (DAC) and headphone amplifier based on proprietary technology.

Engineered around an enormously powerful, custom-coded FPGA (Field Programmable Gate Array) processor, the Mojo 2 uses Chord Electronics’ proprietary digital audio code which has been perfected and refined over more than two decades. This unique architecture delivers class-leading sound quality, whether used on the go with headphones, or as a desktop or hi-fi system component.

Key to the Mojo 2 is the world’s first lossless Digital Signal Processor (DSP). The innovative ‘UHD DSP’ is fully transparent, enabling comprehensive tone adjustments across the frequency range without any degradation in sound quality. This unique technology gives Mojo 2 unrivaled adaptability when connected to other hardware, plus exceptional control over digital music regardless of age, recording quality or genre.

A further key feature over the original Mojo is the introduction of a button-operated menu system bringing a mute function, a four-setting crossfeed adjustment, a button-lock feature for traveling, plus control over the lossless tone controls and USB-C charging.

The Mojo 2 also boasts greatly improved battery management through a new FPGA-based charging system, which ensures faster, cooler, and more efficient charging, with a 75% reduction in power loss and a minimum battery life of over eight hours. It also features an improved Intelligent Desktop Mode, allowing for permanent connection to a power source without compromising sound quality or battery longevity.

Digital inputs include the (newly updated) switchable USB-C data/charging port, Micro-USB data, optical, and coaxial (including dual-data for use with the M Scaler).

Handmade in the UK, the precision CNC-milled aircraft-grade aluminium chassis offers peerless build quality, befitting its status as the leading portable DAC device. Thanks to the continued use of Micro-USB, the Mojo 2 remains fully compatible with the Poly streamer/server module for wireless streaming flexibility and Micro SD card playback.

• New 4.4 mm output: Replaces one 3.5 mm socket, for greater compatibility with a wider range of high-end headphones.
• New selectable USB-C charging: Now supports switchable USB-C charging using the USB-C data input, simplifying connectivity and power management within a single standard.
• World’s first lossless DSP: Fully transparent 104-bit DSP for lossless tone control across the frequency range; unrivaled device compatibility without sound degradation.
• Menu system: polychromatic control spheres for easy navigation of the DSP, mute function, crossfeed and more.
• Advanced power management: FPGA-controlled charging offers faster, cooler charging, 75% reduction in power loss, and minimum battery life of better than eight hours.
• Connectivity: Four digital inputs including USB-C, Micro-USB (data), optical, and coaxial (incl. dual-data).
• Proprietary tech: Custom-coded FPGA architecture, advanced proprietary WTA filter (40,960 taps), and advanced Pulse Array DAC for class-leading transparency and dynamics.
• British made: Designed, engineered and handmade in the UK from high-grade, precision CNC-milled aluminum.
• Take Mojo 2 wireless with the Poly streamer/server (1 TB+)

For more than 25 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.
