Self-Patented Current Mode For Powerful Driving Force

Questyle M12 features the brand’s self-patented “Current Mode” amplifier technology. As the “engine” of the headphone system, an amplifier plays a vital role in the output quality. 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 Detection

Questyle M12 features intelligent impedance detection technology. The device intelligently detects the impedance of the connected headphones and adapts according to them, ensuring a great experience for its users. For example, for difficult-to-drive high-impedance headphones, M12 will use the corresponding high-gain level to provide extra power. When driving low-impedance headphones the output level will switch to a low-gain level. M12 switches to high-gain for headphones with impedance above 70 ohms, below it will use low-gain mode. For anything of 600-ohm impedance or above, M12 switches to line-out mode with an output level of up to 2Vrms.


High-Quality Audio Signal Decoding

Questyle has partnered with ESS Sabre Technologies to bring a true-to-life high-resolution audio performance with its M12 Mobile DAC/AMP. M12 is equipped with an ES9281AC decoding chip that enables it to support high-resolution audio signal decoding with ultra-low distortion and clean noise-free background. It supports PCM decoding up to 32-Bit/384kHz and DSD up to DSD256 natively.

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.


Extremely Compatible

Questyle Labs has done a lot of testing and targeted optimization on the compatibility of the M12 with mainstream mobile phones and tablets. It is fully compatible with any smartphone running on Android V5.1 and above. For PC is supports Windows 10 and MAC systems with no requirement for any specialized driver installation.
