A Fully Modern Technological Core
The M7 is FiiO's first player to use Samsung's Exynos 7270 SoC (system on chip), made on the 14nm FinFET process. Compared to being made on the older 28nm process, the Exynos 7270's two ARM Cortex A53 cores use 20% less power for greater power efficiency and better battery life. The Exynos 7270 is also made with Samsung's groundbreaking SiP-ePoP packaging technology -this allows the storage, power management, and memory chips to be all crammed with the ARM cores into a single tiny package 40% smaller than if the chips were packaged separately such as in existing technologies.This extra space allows for better cooling, and most importantly, a bigger battery to greatly improve play time.
State-of-the-art 6-layer multi-stage Blind and Buried Via PCB technology
Because of the Exynos 7270's SiP-ePoP packaging technology, integrating it with the rest of the M7's printed circuit board (PCB) was a challenge but also allowed us to explore and implement new technologies. Thus, the M7 is the first digital audio player to contain a 6-layer multi-stage HDI (high density interconnect) PCB, the same kind that is used in the latest smartphones. Being only 0.8mm thick, this allowed us to cram much more functionality into the body of the M7. Furthermore, we also employ blind and buried vias on the PCB, which allows the different components to work more closely in harmony as well as make the power supply section much more robust, guaranteeing superior first-rate sound quality.
The next step in audio: high fidelity wireless
The M7 utilizes a Samsung Bluetooth 4.2 chip that supports the aptX-HD audio codec, allowing you to enjoy your music in high fidelity without the hassle of wires. In addition, the M7 also supports Sony's LDAC wireless audio codec, which compared to ordinary Bluetooth audio transmits 3x the data for an unparalleled, truly high -resolution audio experience.
ESS Sabre 9018 chip for unsurpassed sound quality
Within the core of the M7 lies the Sabre 9018Q2C chip by ESS, an SoC that neatly combines a high-performance DAC and headphone amplifier into one tiny package. What separates this ESS chip from other commonly used combo audio chips are: (1) the 9018Q2C has two independent power supplies, one each for the digital and analog sections (2) the internal headphone amplifier has its own independent dual power supply and (3) adjustable LPF (low-pass filter), which provides developers with more flexibility to make the product sound exactly the way they want. All in all, the 9018Q2C saves space on the PCB, reduces power consumption compared to competing solutions, and all while delivering up to 49mW of output power at a THD+N of -100 dB. * The 9018Q2C has a signal-to-noise ratio of -121 dB, THD+N of -115 dB, and support for up to 384kHz/32 bit PCM and 11.2 MHz DSD (DSD256) audio
Discover a whole new world of FM radio
Within the M7 lies a whole another world of FM radio! Unlike many other comparable players, the M7 contains a dedicated FM chip, the Si4705. This is a specialized DSP with excellent FM reception and is not very prone to interference that outputs a digital signal directly to the ESS 9018Q2C. In order to further boost radio signal reception strength, the FM chip uses your headphones as an antenna. FM frequencies covered is the broad range of 76MHz – 108MHz, which is essentially all of the possible spectrums used around the world.
Why worry about charging with 40 days of standby time?
Lying within the M7 is an 1180mAh battery that, thanks to the Exynos 7270's advance 14nm fabrication process, allows the device to have a play time of 20 hours or more, or a standby time up to a whopping 40 days! In standby mode, you can instantly wake up the device so you can enjoy your music immediately whenever you want while still saving tons of power.
