FiiO JadeAudio GIGAS 1 Desktop Headphone Amplifier, 4600mW High-Power Balanced Output, Class AB Discrete Circuit, 4.4mm & 3.5mm Amp for Planar & High-Impedance Headphones (Black)

About this item

【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. 【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. 【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. 【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. 【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.
