FiiO JadeAudio GIGAS 1

The FiiO GIGAS 1 is a compact desktop headphone amplifier designed to provide high output power for a wide range of headphones and IEMs. Its discrete Class-AB architecture uses a transistor current amplification circuit to deliver powerful and low-impedance output performance.

With output power of up to 4600 mW + 4600 mW, the GIGAS 1 is designed to handle everything from sensitive IEMs to low-sensitivity planar headphones and high-impedance full-size headphones. Two adjustable gain levels make it easy to match the amplifier to different headphone types.

The amplifier provides both 3.5 mm single-ended and 4.4 mm balanced headphone outputs. The 3.5 mm output also supports CTIA-compliant microphone passthrough for gaming voice chats, calls and multimedia use.

Two inputs, 3.5 mm and RCA, provide flexible connectivity with digital audio players, smartphones, computers, CD players and other source devices. The GIGAS 1 is also compatible with FiiO TRUST and LINK series cables.

Power is supplied through USB-C, with support for standard 5 V power and 12 V USB PD input. The amplifier automatically adjusts to the available power supply, while 12 V PD operation unlocks the GIGAS 1's higher power capability.

The minimalist aluminum alloy housing features an oversized volume control and mechanical toggle switches for intuitive operation. The anodized housing is available in black, silver and green finishes, complemented by a warm retro lighting effect.
