FiiO QX11 Portable Gaming Decoder & Amplifier | Dual ES9069Q DAC & 800mW Desktop Mode

Bridge the gap between pure high-fidelity listening and competitive gaming with the FiiO QX11. Functioning as both a high-resolution portable USB DAC/AMP and a gaming sound card, the QX11 features dual flagship ESS ES9069Q DACs, a parallel quad TI op-amp architecture, web & app Auto EQ support, and FiiO's patented Desktop Mode capable of delivering a massive 800mW + 800mW output.

Key Highlights

• Dual Flagship ES9069Q DACs: Utilizes two 4th-gen ESS HyperStream ES9069Q 32-bit DAC chips for a pitch-black background noise floor and detailed audio retrieval.

• High-Res PCM 768kHz & Native DSD512: Complete high-resolution decoding support for PCM files up to 32-bit/768kHz and native DSD512.

• Parallel Quad TI Op-Amp Stage: Engineered with 2x TI OPA1692 voltage amps and 4x TI OPA1622 headphone output amps operating in parallel for low distortion and strong current delivery.

• Patented Desktop Mode (800mW + 800mW): Engages high-power amplification mode via external power to drive demanding full-sized headphones effortlessly.

• Dual Operating Modes: Switch between dedicated HiFi Mode (for pure musical fidelity) and Gaming Mode (low latency with tuned sound presets).

• Game-Tuned DSP Presets: Tailored sound profiles for FPS, ACT, MOBA, and MUG (Rhythm) games to enhance footstep audio, skill sound effects, and spatial positioning.

• Built-In Mic & AI ENC Noise Cancellation: Integrated microphone with AI Environmental Noise Cancellation, sidetone monitoring, and support for 3.5mm headsets with in-line controls.

• Dual Type-C Ports with 45W PD Pass-Through: Independent data and power ports supporting up to 45W USB Power Delivery pass-through charging.

• Advanced Web & App Auto EQ: Full 10-band Parametric EQ (PEQ) with Auto EQ headphone curve matching via web interface and the official FiiO Control app.

Product Description

Dual Flagship Audio Circuitry

At the heart of the FiiO QX11 is a dual ESS ES9069Q DAC setup. Combined with an end-to-end Texas Instruments analog architecture—comprising two TI OPA1692 voltage gain chips and four TI OPA1622 output chips in parallel—the QX11 delivers a Signal-to-Noise Ratio (SNR) of up to 126dB and ultralow THD+N (<0.00043%). Every minute detail of your favorite high-resolution FLAC or DSD track is retrieved with pristine accuracy.

Desktop-Grade Power with Play & Charge Design

When connected to an external power supply via its dedicated Type-C POWER IN port, the physical Desktop Mode switch unlocks up to 800mW + 800mW @ 32Ω on the 4.4mm balanced output (and up to 295mW + 295mW on the 3.5mm output). With 45W USB Power Delivery pass-through support, you can charge your smartphone or host device during long listening sessions or competitive gaming marathons.

Dual HiFi & Gaming Modes with AI ENC Comms

The QX11 features dedicated UI environments and processing for audio and gaming:

• HiFi Mode: Pure, unadulterated decoding with full 32-bit/768kHz and DSD512 support.

• Gaming Mode: Custom DSP profiles tuned specifically for FPS (enhanced footsteps/spatial cues), MOBA (ability notifications), ACT (action immersion), and MUG (rhythm precision).

In-game communications stay crisp thanks to the onboard physical microphone paired with AI Environmental Noise Cancellation (AI ENC). For headset users, the 3.5mm jack fully supports CTIA-standard in-line microphone controls.

Auto EQ & 10-Band PEQ

Personalize your acoustic profile through web-based tools and the FiiO Control mobile app. The 10-band Parametric EQ (PEQ) features Auto EQ, allowing you to automatically match frequency response curves to specific IEMs and headphones for seamless, one-touch tuning.
