Continue with the classic - Chord Mojo 2

There is no display, and simple color lights are used to express various functions and volumes, and Chord Mojo is the best in portable audio. At a glance, you can see the characteristics of its products, the unique style of Mojo, as early as 2015 appeared, the fusion of "Mobile" and "Joy", the two English and named Mojo, designed and produced in the United Kingdom, with a strong British flavor, classic and modern style, leading the portable audio industry set off a "tied" boom.

Seven years later, Now Chord Electronic has released its second-generation purpose:

Mojo 2

Inherited style, modern specifications

Only the circular button is used to control all functions, only Chord Mojo is the first to inherit this DNA, and Mojo2 will not be an exception. First of all, the size and appearance of Mojo2 are almost the same as the previous generation, inheriting the symbolism and uniqueness of the previous generation, which can make old users have a sense of belonging and operation.

Hardware boost, density multiplier

Condensing the technology to one hand, but although the sparrow is small and complete, Mojo also inherits various characteristics of the Chord family, such as the iconic glass boule operation button. Mojo is an all-metal body, the corners are polished and sleek, the surface is matte black oxidation treatment, and the safety factor will be higher when bundled with mobile phones and large-screen players, and it has a good touch.

Unlike most of the portable decoding ear amplifiers on the market, CHORD Mojo 2 is not using a ready-made DAC scheme, but using Spatan FPGA (programmable gate array) to create, the implementation of the decoding function is completed by the program, CHORD in the FPGA is very deep, FPGA has also become its core technology, widely used in Hugo, Hugo TT, 2Qute and other products, its decoding performance is often better than the existing DAC chip solutions, such as Mojo 2 Can achieve up to 768KHz sample rate audio decoding as well as DSD512 decoding, very powerful.

Intimate function, simple control

Spherical glass elements and buttons are a major feature of CHORD decoding ear amplifiers, which are used on both Hugo and Hugo TT, or transparent spherical sunroofs, or volume knobs that emit light and change color, making CHORD full of scientific and technological beauty.

Minimalist design, bag size

Condensing technology to the point where you can grasp it all, but the Sparrow is small and well-equipped, Mojo 2 inherits various features of the Chord family, such as the iconic bocce button. Mojo 2 is an all-metal body, the corners are polished and smooth, the surface is matte black oxidation treatment, and the safety factor is higher when bundled with mobile phones and large-screen players, and it has a good touch. Chord Mojo 2 provides two 3.5mm stereo headphone jacks that can be used simultaneously, making it easy for 2 people to enjoy music at the same time.

Own decoding FPGA

Mojo 2 adds USB Type C data input, adding the lower shell needs to be enlarged to open the design

Supports 32bit/768kHz and DSD256 audio

The core of Mojo 2 is still based on the FPGA chip, combining digital processing and DAC functions, and has been improved to have lower noise floor, more transparent sound quality, and can support higher sample rate file replay. In addition, the new FPGAs feature advanced power management features, coupled with increased battery capacity, which in turn increases the endurance of the Mojo 2. Battery life of up to 8 hours of continuous use after increased battery capacity.

Crossfeed feature

When the menu button is dark blue, pressing the "+" option will cycle through the Crossfeed options. Complete cross-feeds to improve imaging and soundstage to showcase your music. When using headphones, the effect will be more obvious.

There are four options available:

Red: Minimum

Green: Moderate

Blue: Maximum

Off: Cross feed

UHD DSP tuning function

The Mojo 2 and Poly are paired for easy portable audio users

Without lossless sound quality, it can be made in a segmented independent tuning, and can be adjusted by +9, -9 and close for a total of 19 levels, so that the user can make appropriate adjustment/correction functions according to their preferences/headphone characteristics/song file to a certain extent:

Ultra-low frequency 20Hz ~ 125Hz (power supply red light catalog)

Close to the lower limit of human hearing of 20Hz, to 125Hz hertz adjustment, is conducive to the expression of low-frequency instruments, such as bass knots, drums and other instruments, so that its prominent positioning, sound pressure, sound field and so on, is almost the starting point of male vocals.

Low to IF 20Hz~3kHz (Power Supply Orange Lamp Catalog)

Usually the range values of the male and female voices, which can be adjusted more and less to control their positioning, sound field, certain tooth sounds, stereoscopic and so on. The frequency band that can be called the middle and lower discs can be adjusted.

Medium to high frequency 125Hz~3kHz (power supply green light catalog)

The general string music, guitar, etc., the range is very wide, so that the overall soundstage and knot will have obvious changes. The frequency band that can be called the upper mid-disk is adjusted.

Up to UHF 3kHz~20kHz (power supply light blue lamp catalog)

This band is basically inaudible with human hearing, but it is also necessary to exist, because this is exactly the sound we "feel", although it is very abstract, but it has its own reason, because we "listen" to the sound in addition to the ear, in fact, the whole body and even the skin can feel the existence of sound. And this frequency band will make people feel a more abstract feeling like the sense of air, you can adjust this frequency band to try to see if there is a "feeling".

The wireless streaming module "Poly" is designed for Mojo, and the internal circuit architecture adopts a 10-layer PCB design, which can reduce the size, transmit faster and consume less power by narrowing the path to the shortest. The most important wireless streaming features can be directed to WiFi (DNLA), AirPlay, Bluetooth 4.1, and the increasingly talked about "Roon", and the built-in capacity-free Micro SD card slot makes Mojo no longer trapped by "cables". Music sampling rate up to 768kHz, DSD512, file formats more support ACC, WAV, FLAC, AIFF, OGG VORBIS, ALAC, WMA, MP3, for pay attention to sound quality, performance, and like to use wireless streaming without restraint, as long as through WiFi (DNLA APP), AirPlay, Roon, Bluetooth can easily play music

The difference between Mojo and Mojo 2 sounds

Everyone wants to know the difference between Mojo and Mojo 2, so let's briefly share my feelings about the two:

Mojo is generally more grainy, the sense of music is more intense, a little bit dry, but this little bit of dryness makes the music with a little rough feeling, the original sense of style. The soundstage is not a gorgeous trend, but a real high degree of reduction of the machine, will not have a delicate and contrived taste, but faithfully express the original characteristics held by the actual music archives.

Mojo 2's performance has a clear leap forward on the basis of Mojo, the most obvious is the ability to control the bottom dryness and analysis, making the background very quiet, but without sacrificing analytical power. The soundstage is noticeably wider and deeper than the first generation, a circular extension. (Turn off the sound sensation under UHD DSP tuning)
