Chord Electronics, a world leader in digital audio, has launched Mojo. A contraction of ‘Mobile Joy’, Mojo is a headphone amplifier and DAC (digital-to-analogue convertor) that empowers smartphones to deliver music content at up to studio-master-tape quality. Mojo enables this due to Chord Electronics’ advanced proprietary digital signal processing technology.
Low-cost, widely available apps, such as Onkyo’s HF player (iOS and Android), now make high-resolution music file playback easy from all smartphones. Mojo connects to these devices digitally, processing the files using the most advanced conversion technology available, to deliver genuinely unrivalled sound quality to up to two pairs of headphones.
The Chord Electronics Mojo headphone amp and DAC is entirely designed and manufactured in England using British expertise. It distils 27 years of high-performance audio know-how into a single mass-market device designed to empower the smartphone. Mojo is the most advanced device of its kind in the world.
Mojo connects digitally to smartphones and similar devices in a number of ways. It offers three different high-resolution digital inputs: Micro USB, optical and a 3.5mm coaxial input. Input selection is fully automatic: if more than one input is active, they are prioritised as USB first, coaxial second and optical third.
A Micro USB to USB cable is supplied with each Mojo and Chord Electronics will be offering consumers a range of approved, low-cost connecting cables for iOS devices and various other digital connections.
The Chord Electronics Mojo utilises new high-temperature battery technology, giving much faster charging (up to twenty hours’ faster than competitor units). A full charge is reached in just four hours via USB, giving around ten hours’ playback; Mojo’s charging Micro USB port has a battery status and charging indicator light, too.
Mojo’s ultra-compact form, based on Chord’s award-winning Hugo platform, has been designed to be easily operated with no confusing or superfluous switches. Its simplicity means anyone can enjoy high-end sound quality straight out of the box. Mojo’s casework is machined from solid aircraft-grade aluminium and has a hard, fine Matt-black finish that does not finger-mark.
The Chord Electronics Mojo is capable of playing all of today’s music formats, including the very latest high-resolution standards. It can deliver breath-taking realism from any digital music file: PCM; WAV; AAC; AIFF; MP3 and FLAC. It is designed to work with all smartphones and music players and covers specialist high-resolution formats such as DoP DSD files: DSD 64; DSD 128 and DSD 256. Mojo’s three high-resolution digital input options comprise optical (to 192kHz), plus Micro USB and RCA (mini-jack) which operate at up to an incredible 768kHz.
Mojo uses the new Artix-7 FPGA chipset from Silicon Valley’s Xilinx, making Mojo the most advanced DAC of its type on the planet! Unlike other audio products, that process digital files using crude off-the-shelf chips from Asia, Chord uses an FPGA — a programmable circuit that enables its skilled engineers to directly implement its own digital audio expertise, making Mojo unique in the marketplace.
Mojo uses spherical buttons for power on/off, volume control and file frequency information. The spheres illuminate and cycle through a range of rainbow colours. The file frequency is shown clearly by an indicator colour option on the power switch: from CD-quality (44.1kHz, red), 48kHz (orange) and so on, up through a rainbow of colours to bright white for DSD. Volume levels are similarly represented using colour.
