Why You Should Get It
  • 【Class AB Discrete Amplification for Natural Sound】 Built around a carefully engineered Class AB amplifier architecture using ON Semiconductor MJE243G/MJE253G transistor pairs. The discrete output stage delivers high current capability with a smooth, natural, and engaging sound signature.
  • 【Up to 4600mW+4600mW Balanced Output】 Delivers up to 4.6W per channel through the 4.4mm balanced output at 32Ω, providing powerful drive for demanding planar magnetic and high-impedance headphones while maintaining excellent control over sensitive IEMs.
  • 【4.4mm Balanced & 3.5mm Outputs】 Supports both balanced and single-ended headphones. The 3.5mm output also supports CTIA microphone pass-through, making it suitable for gaming headsets, calls, and multimedia applications.
  • 【Flexible Inputs & Gain Modes】 Compatible with DACs, music players, smartphones, computers, CD players, and other audio sources through RCA and 3.5mm inputs. Dual gain modes optimize performance from sensitive IEMs to power-hungry headphones.
  • 【USB-C Dual Power Modes & Cable Bundle Option】 Supports standard 5V USB power and PD 12V power delivery. With PD 12V input, GIGAS 1 unlocks higher output capability with greater dynamics and headroom. A cable bundle option is also available for a more convenient desktop audio setup.

The GIGAS Series takes its inspiration from the Greek word "GIGAS," meaning "giant," which symbolizes high output power.

 

This product series was born out of our release of the JT7 planar over-ear headphones. The JT7 has a relatively low sensitivity and demands high output power from the source device, but source equipment on the market with sufficient power are often quite expensive. To address this, we have tailored the GIGAS Series specifically for entry-level planar headphones from FIIO and other brands, delivering massive driving power at an affordable price—to fully unlock the true sound quality of full-size planar headphones.

 

The GIGAS 1 is a compact, high-power headphone amplifier specially designed for desktop usage.

 

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 and IEMs with ease - delivering a smooth, natural, and melodious sound.

Dual headphone outputs, Seamlessly compatible

Featuring 3.5mm single-ended and 4.4mm balanced headphone outputs, the GIGAS 1 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.

High and low gain settings, 5V and 12V PD power supply…More features await your discovery!
