UHD DSP for Precision Sound Control

Mojo 2 introduces the world’s first lossless DSP, offering precise tone control across the full frequency range without any degradation in sound quality. This breakthrough technology ensures compatibility with a wide range of headphones and audio formats, delivering a perfect listening experience every time.

The custom 104-bit DSP core operates at 705/768 kHz, enabling 18 levels of adjustment per frequency band for detailed fine-tuning of bass, mid-bass, treble, and high treble.

Improved Functionality and Battery Life

The new menu system offers features like mute, four levels of crossfeed, and a button lock for travel. Volume control has also been refined, with an expanded range from +18 dB to -108 dB and two operational modes for low and high volumes.

A new FPGA-based battery system allows for faster charging, reduced power loss, and cooler operation. With an increased capacity, the Mojo 2 offers over eight hours of playback time. Its enhanced Intelligent Desktop Mode lets users bypass the battery for uninterrupted desktop use without affecting sound quality.

Superior Sound Clarity

Thanks to a digital DC servo and DC coupling, the Mojo 2 is more transparent than ever. Its improved WTA filter, with 40,960 taps and 40 DSP cores, enhances clarity and reduces noise. Additionally, an updated noise-shaper and refined 4e Pulse Array DAC improve detail retrieval while lowering distortion and out-of-band noise, creating an ultra-neutral sound profile without the use of coupling capacitors.

COMPATIBLE WITH POLY FOR STREAMING

Completely compatible with our Wireless streaming module Poly, Poly allows for wireless integration to your system.

About Chord Electronics

Chord Electronics first took flight from the aviation world, where engineering without limits means uncompromising standards. This concept designed by company owner John Franks has helped shape our philosophy since the company’s inception in 1989.  Our first amplifiers were supplied to the BBC, followed by world-leading studios including Abbey Road, Sony Music (New York) and later, The Royal Opera House.

Our reputation within the professional world generated demand for a domestic range encompassing the design, engineering and build standards demanded of the finest pro equipment. Today, we apply proprietary technologies to all of our British-made products and proudly deliver studio-grade audio performance across the entire Chord range.
