Aroma Audio Air 是一款發燒級便攜藍牙解碼耳擴(DAC/Amp),搭載參考級 ES9038Q2M 晶片。Air 專為長久耐用與可玩性而設計,採用可更換的 18650 電池與可插拔運放(Op-Amp)架構,讓您能自由更換晶片以調整音色。支援 LDAC/aptX-HD 高清格式,並透過 4.4mm 平衡輸出驅動高阻抗耳機。
Air: The "Forever" Wireless Hub
In a market flooded with disposable Bluetooth dongles, the Aroma Audio Air stands apart as a sustainable, desktop-class wireless solution. It solves the two biggest problems of portable audio: battery degradation and sonic stagnation. By utilizing a replaceable 18650 battery system and a socketed Op-Amp motherboard, the Air is designed to be the last Bluetooth receiver you will ever need.
Desktop-Class Architecture
The Air is not a toy; it is a miniaturized desktop system.
- The Brain (DAC): We utilize the ESS Sabre ES9038Q2M, a reference-class chip known for its hyper-detailed retrieval and wide dynamic range (124dB SNR).
- The Muscle (Amp): Unlike standard dongles that struggle with high-impedance loads, the Air's balanced circuit is optimized for voltage swing, delivering 400mW @ 300Ω, making it capable of driving demanding full-size headphones (like the Sennheiser HD600 series) with authority.
The Tuner’s Playground
Why settle for one sound? The Air features a Quick-Swap Op-Amp Socket, allowing you to physically change the Operational Amplifier chip to alter the sound signature.
- Stock Configuration: Tuned for transparency and speed.
- Customization: Swap in a Burson or Muses chip (sold separately) to add warmth, tube-like harmonics, or analytical precision.
Infinite Power Cycle
The internal power source is a standard 18650 Li-ion battery (3400mAh).
- The Benefit: When the battery degrades after years of use, you don't throw the device away—you simply pop in a new $10 battery.
- On-the-Go: Carry a spare battery for instant 0-100% recharge during long flights or remote listening sessions.
Connectivity & Filters
- Inputs: Bluetooth 5.0 (LDAC, aptX-HD, aptX-LL, AAC, SBC) or USB-C DAC mode.
- Outputs: 4.4mm Balanced, 2.5mm Balanced, and 3.5mm Single-Ended.
- Digital Filters: 8 user-selectable filters (via power button) to fine-tune the transient response and roll-off.
Air:無線音頻的「永續」樞紐
在充斥著「一次性」藍牙產品的市場中,Aroma Audio Air 以其可持續性和桌面級架構獨樹一幟。它解決了便攜音頻的兩大痛點:電池老化與聲音固化。通過採用可更換 18650 電池系統和可插拔運放(Op-Amp)母座,Air 被設計為您可以長期擁有的終極無線伴侶。
桌面級架構 (Desktop-Class Architecture)
Air 不是普通的藍牙接收器,而是一個微縮的台式系統。
- 大腦 (DAC): 搭載 ESS Sabre ES9038Q2M 參考級晶片,以其超高的解析力和寬廣的動態範圍 (124dB SNR) 著稱。
- 推力 (Amp): 不同於在驅動高阻抗耳機時乏力的普通「小尾巴」,Air 的平衡電路專為高電壓擺幅優化,在 300Ω 時可輸出 400mW,足以從容驅動如 Sennheiser HD600 等高阻大耳牛。
調音師的遊樂場
為何滿足於一種聲音?Air 配備了快拆式運放插座,允許您通過物理更換運放晶片(Op-Amp)來改變聲音特質。
- 原廠配置: 專為通透度與速度感調校。\
- 客製化: 您可以自行換入 Burson 或 Muses 等發燒運放(需另購),為聲音增添溫暖的膽味或極致的分析力。
無限續航循環
內部電源採用標準的 18650 鋰離子電池 (3400mAh)。
- 優勢: 當電池經年使用老化後,您無需丟棄設備,只需更換一顆標準的 18650 電池即可滿血復活。
- 戶外應用: 在長途飛行或旅行中,攜帶備用電池即可實現「瞬間滿電」,告別充電焦慮。
連接與濾波
- 輸入: 藍牙 5.0 (支援 LDAC, aptX-HD, aptX-LL, AAC, SBC) 或 USB-C DAC 模式。
- 輸出: 4.4mm 平衡, 2.5mm 平衡, 以及 3.5mm 單端。
- 數位濾波: 內建 8 種數位濾波模式(通過電源鍵切換),可微調瞬態響應與高頻滾降特性。
