Questyle M12 is an advanced mobile HiFi headphone DAC and amplifier featuring an advanced ES9281AC ESS Sabre DAC chip providing best-in-class audio performance with ultra-low distortion. Questyle M12 is capable of providing clean and powerful output thanks to the brand’s self-developed “Current Mode” independent headphone amplifier technology. Powerful Driving Force With Advanced Current Mode Technology:- Questyle has developed an advanced “Current Mode” technology that is the main USP of their award-winning products. Questyle has brought that technology for mobile users with the portable M12. M12 is not limited by the power of OPAMP chips, it has ultra-high current output capability and control. Even with such a powerful driving force, the device has an ultra-low distortion rating of just 0.0003%. Intelligent Impedance Adaptive Technology:- Questyle M12 features low and high-gain modes that it switches automatically adapting to the power requirement of the connected headset. M12 features an intelligent impedance adaptive technology that changes the gain mode as per the impedance rating of the connected headphones. It switches to the high gain mode for headphones with 70 ohms and above impedance below it sticks to the low gain mode. When we connect 600 ohms headphones it switches the output automatically to line out mode with a 2V output level. MQA Decoding Support:-  Questyle M12 supports MQA rendering and completes the final development of MQA files. When the LED indicator is glowing magenta color, it means the M12 is rendering the MQA file and the final development of the MQA file is being completed.  Hi-Resolution Audio Signal Decoding:- Questyle M12 features an advanced ES9281AC audio signal decoding chip by ESS Technologies. It provides high-resolution audio signal decoding with ultra-low distortion and pitch-dark noise-free background in the output. M12 supports  PCM decoding up to 32-Bit/384kHz and DSD up to DSD256 natively.  Compatible With Most Devices:- Questyle M12 is designed and developed keeping in mind support for most devices straight out of the box. It can be used with any Android device with Android V5.1  and above. For PC is supports Windows 10 and MAC systems with no requirement for any driver installation.   Tech Specs Spec: – Operating system required Android phone and pad: Android 5.0 and above PC: Win10 1803 and above Apple cellphone: iOS (You need to buy an OTG cable for Lightning to Type-C.) Apple computer: Mac OS – DAC Capability of M12: PCM: 32kHz – 384kHz (16/24/32Bit) DSD: DSD64(1Bit 2.8MHz) , DSD128(1Bit 5.6MHz), DSD256(1Bit 11.2MHz) – Output Power: Built-in smart detection circuit will automatically self-adjust the output power to fit different impedance of headphones. RL=16Ω，Po=46.11mW; RL=32Ω，Po=26.71mW; RL=300Ω，Po=12.26mW; When the detected impedance is less than 70Ω, M12 will self-adjust to low gain output. When it is more than 70Ω, M12 will self-adjust to high gain output. When it is more than 600Ω, M12 will automatically switch to 2Vrms line out.
