Built around a \u003cstrong\u003ediscrete Class AB transistor current-amplification circuit\u003c\/strong\u003e, the GIGAS 1 provides high-current, low-impedance output and up to \u003cstrong\u003e4600mW + 4600mW balanced output power\u003c\/strong\u003e with a 12V PD power supply.\u003c\/p\u003e\n\u003cp\u003eDesigned with both \u003cstrong\u003eIEMs and full-size headphones\u003c\/strong\u003e in mind, the GIGAS 1 features two gain levels, 4.4mm balanced and 3.5mm single-ended headphone outputs, plus 3.5mm and RCA inputs. Its compact aluminium alloy chassis makes it well suited to desktop listening setups where space is limited without compromising on driving power.\u003c\/p\u003e\n\u003ch2\u003eDiscrete Class AB Amplification\u003c\/h2\u003e\n\u003cp\u003eAt the heart of the GIGAS 1 is a discrete amplification circuit combining an op-amp with transistor current amplification. The circuit uses \u003cstrong\u003eON Semiconductor MJE243G and MJE253G transistors\u003c\/strong\u003e, enabling high-current and low-impedance output. With up to \u003cstrong\u003e4600mW + 4600mW of balanced output power\u003c\/strong\u003e, the amplifier is designed to drive full-size headphones and IEMs with ease.\u003c\/p\u003e\n\u003ch2\u003e4.4mm Balanced and 3.5mm Headphone Outputs\u003c\/h2\u003e\n\u003cp\u003eThe GIGAS 1 provides both \u003cstrong\u003e4.4mm balanced\u003c\/strong\u003e and \u003cstrong\u003e3.5mm single-ended headphone outputs\u003c\/strong\u003e, offering compatibility with a wide range of headphones. The 3.5mm output also supports \u003cstrong\u003eCTIA-compliant microphone passthrough\u003c\/strong\u003e, making it suitable for gaming voice chat, vocal calls and multimedia entertainment.\u003c\/p\u003e\n\u003ch2\u003eFlexible 3.5mm and RCA Inputs\u003c\/h2\u003e\n\u003cp\u003eWith both \u003cstrong\u003e3.5mm and RCA inputs\u003c\/strong\u003e, the GIGAS 1 can be connected to a wide range of source equipment, including digital audio players, smartphones, computers and CD players. It can be used for HiFi music listening as well as desktop multimedia entertainment.\u003c\/p\u003e\n\u003ch2\u003eTwo Gain Levels\u003c\/h2\u003e\n\u003cp\u003eA simple toggle switch lets you select between \u003cstrong\u003ehigh and low gain\u003c\/strong\u003e. This allows the GIGAS 1 to accommodate high-sensitivity IEMs as well as low-sensitivity planar headphones and high-impedance full-size headphones.\u003c\/p\u003e\n\u003ch2\u003e5V and 12V PD Power Input\u003c\/h2\u003e\n\u003cp\u003eThe GIGAS 1 uses a \u003cstrong\u003eUSB Type-C power input\u003c\/strong\u003e and supports both standard \u003cstrong\u003e5V power\u003c\/strong\u003e and \u003cstrong\u003e12V PD power\u003c\/strong\u003e, automatically adapting between modes. A computer or 5V adapter can power the amplifier for most headphones, while a 12V PD power supply unlocks its higher driving power, dynamics and soundstage.\u003c\/p\u003e\n\u003ch2\u003eCompact Aluminium Alloy Design\u003c\/h2\u003e\n\u003cp\u003eThe GIGAS 1 features a minimalist aluminium alloy chassis measuring approximately \u003cstrong\u003e132 × 60 × 40mm\u003c\/strong\u003e excluding the feet, with a weight of approximately \u003cstrong\u003e210g\u003c\/strong\u003e. Its compact design makes it easy to integrate into smaller desktop setups, while the oversized volume knob and mechanical toggle switches provide straightforward control.\u003c\/p\u003e\n\u003cp\u003eThe amplifier is available in \u003cstrong\u003eblack, silver and green\u003c\/strong\u003e, with an anodized aluminium alloy finish and warm retro lighting designed to complement a variety of desktop environments.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePower Input:\u003c\/strong\u003e 5V⎓2A Type-C; PD 12V⎓2A Type-C\u003cbr\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e RCA, 3.5mm\u003cbr\u003e\u003cstrong\u003eHeadphone Outputs:\u003c\/strong\u003e 4.4mm balanced, 3.5mm single-ended\u003cbr\u003e\u003cstrong\u003eSupported Impedance:\u003c\/strong\u003e 8–350Ω\u003cbr\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz–200kHz, attenuation \u0026lt;0.4dB\u003cbr\u003e\u003cstrong\u003eSNR:\u003c\/strong\u003e ≥118dB (A-weighted)\u003cbr\u003e\u003cstrong\u003eNoise Floor:\u003c\/strong\u003e \u0026lt;10.6μV (A-weighted)\u003cbr\u003e\u003cstrong\u003eTHD+N:\u003c\/strong\u003e \u0026lt;0.00057% (1kHz\/-5dB@32Ω)\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e Approximately 132 × 60 × 40mm, excluding feet\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e Approximately 210g\u003cbr\u003e\u003cstrong\u003eColours:\u003c\/strong\u003e Black, Silver, Green\u003c\/p\u003e\n\u003ch3\u003eMaximum Output Power with 12V PD Input\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e4.4mm Balanced:\u003c\/strong\u003e\u003cbr\u003e32Ω: 4600mW + 4600mW\u003cbr\u003e16Ω: 3300mW + 3300mW\u003cbr\u003e300Ω: 740mW + 740mW\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.5mm Single-Ended:\u003c\/strong\u003e\u003cbr\u003e32Ω: 1400mW + 1400mW\u003cbr\u003e16Ω: 2200mW + 2200mW\u003cbr\u003e300Ω: 185mW + 185mW\u003c\/p\u003e\n\u003ch3\u003eMaximum Output Power with 5V Input\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e4.4mm Balanced:\u003c\/strong\u003e\u003cbr\u003e16Ω: 790mW + 790mW\u003cbr\u003e32Ω: 580mW + 580mW\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.5mm Single-Ended:\u003c\/strong\u003e\u003cbr\u003e16Ω: 280mW + 280mW\u003cbr\u003e32Ω: 170mW + 170mW\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003eFiiO GIGAS 1 × 1\u003cbr\u003eUSB Power Cable × 1\u003cbr\u003eQuick Start Guide × 1\u003cbr\u003eWarranty Card × 1\u003c\/p\u003e","brand":"FiiO","offers":[{"title":"Black","offer_id":49222198132953,"sku":"FiiO Jadeaudio Gigas - Black","price":5670.0,"currency_code":"BDT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1337\/7789\/files\/2_32cd2197-390f-431e-a907-f57ca8109915.webp?v=1789040368","url":"https:\/\/gearsforears.com\/bn\/products\/fiio-gigas-1-desktop-headphone-amplifier","provider":"Gears For Ears","version":"1.0","type":"link"}
