Dual THX AAA-78 Amplifiers
With powerful output that can drive most headphones, the dual THX AAA-78 amplifiers in the M11 Pro are engineered to be powerful and efficient, which results in less noise and distortion. The precise and natural sound that THX amplifiers are designed to produce is based on the amplifiers' 8-stage amplification, 0.5% high-precision thin film resistors, 4-way independent power supply, and a 6-layer gold-plated PCB.
The M11 Pro supports MQA decoding, which is meant to deliver truly lossless playback of the original master recording's sound. The MQA is fully authenticated and small enough to stream or download via the FiiO Music app.
Dual Low-Phase Crystal Oscillators
Created by Japan's River Electec, the two independent low-phase noise crystal oscillators inside the M11 Pro are crafted to work with FiiO's own FPGA technology. Together they are meant to allow for any audio processing to experience pure audio signals with greatly reduced distortion.
Doubles as Bluetooth Amplifier
The M11 Pro can be set to Bluetooth Receiver Mode, which allows you to transmit wireless signals through the M11 Pro's advanced audio circuitry to provide improved frequency response and to decrease distortion, noise floor, and crosstalk. The incoming signal can even be sent out to external devices via the built-in coaxial output.
Three Headphone Outputs
FiiO's engineers have incorporated balanced 2.5mm and 4.4mm headphone jacks, as well as your standard 3.5mm single-ended output. With this kind of versatility, you can use your favorite headphones without the need of cumbersome adapters.
Up to 2TB of Storage
It's easy to fill up a portable device's storage with large, lossless audio files. This is why FiiO has given you the ability to augment the 64GB of built-in storage with microSD cards. The M11 Pro has a microSD card slot that can support an (optional) card up to 2TB in size.
