FiiO GIGAS 1 Compact Desktop Headphone Amplifier Silver

The GIGAS 1 is a compact, high-power headphone amplifier specially designed for desktop usage. Encased in a sleek metal chassis, this powerhouse utilises a discrete Class AB transistor current-amplification headphone amp circuit. It delivers a balanced output of up to 4600mW + 4600mW, effortlessly driving a wide range of IEMs and full-size headphones. With dual headphone outputs, dual inputs, two gain levels, dual-mode power supply, and other features, the GIGAS 1 gives you more immersive HiFi listening and audio-visual experiences.

Class AB Discrete Transistor | Current Amplification Headphone Amp Circuit

Meticulously engineered with a discrete amplification circuit, it utilizes an op-amp + transistor current-amplification design. The classic combination of onsemi MJE243G/253G classic allows the GIGAS 1 to achieve high-current and low-impedance output. Delivering a massive balanced output power of up to 4600mW + 4600mW, it drives full-size headphones with IEMs with ease - delivering a smooth, natural, and melodious sound.

Dual Headphone Outputs | Seamlessly Compatible

Featuring a 3.5mm single-ended and 4.4mm balanced headphone outputs, it offers wide compatibility with a diverse range of headphones. The 3.5mm jack supports CTIA-compliant microphone passthrough - allowing for gaming voice chat, vocal calls, and multimedia entertainment with seamless compatibility.

Dual Input Ports | Flexible Connectivity

Equipped with both 3.5mm and RCA inputs, it delivers extensive compatibility with a wide range of source equipment. Seamlessly connect to digital audio players, smartphones, computers, or CD players. Whether for Hifi music listening or desktop multimedia entertainment, the GIGAS 1 ensures a stable connection with zero limitations on your audio sources.

Two Adjustable Gain Levels | Compatible with All Types of Headphones

A toggle switch easily alternates between high and low gain settings. It accommodates high-sensitivity IEMs as well as low-sensitivity planar and high-impedance full-size headphones, effortlessly driving any headphone in your collection.

Type-C Dual-mode Power Supply | Automatic Adaptation

Utilising a Type-C port, the system is compatible with both standard 5V power and 12V PD power, automatically adapting and switching between modes. Powering the device via a computer or a 5V adapter is sufficient to drive most headphones. However, connecting a 12V PD power supply fully unleashes the amplifier's true potential - delivering a massive leap in driving power, dynamics, and soundstage to unlock peak performance.

Minimalist Design | Effortless Control

Crafted with a minimalist aluminium alloy chassis, its refined and compact footprint allows it to blend perfectly into even the most compact desktop setups. The intuitive oversized volume knob and mechanical toggle switches ensure a smooth, user-friendly experience right out the box.

Multiple Colour Options | Elevate Your Desktop Aesthetics

Available in multiple colours - the anodised aluminium alloy chassis features vibrant colours along with a premium, finely textures finish. Paired with a warm, retro lighting effect, it seamlessly adapts to any desktop vibe - whether it's a minimalist workspace, a vintage setup, or a high-performance gaming rig. It stands out not just as a premium audio device, but as a striking aesthetic centrepiece for your desk.
