ANC III 產生與噪音反相的電氣訊號
以並聯方式針對電源線上的 EMI／RFIANC III produces an electrical signal with the opposite phase to the noise
It operates in parallel, targeting mains-borne EMI/RFI
訊號在機內經歷電 → 光 → 電的轉換
光跨過隔離段，兩側無直接電氣連接
再以主動電路重整輸出訊號Inside the unit, the signal travels from electricity to light and back
Light crosses the isolation section without a direct electrical connection
Active circuitry then regenerates the output signal

獨立評測，對應確實型號
早期評測以 iFi 品牌名稱刊登Independent assessments of the exact models
Earlier reviews were published under the iFi name
評論讚賞機身製作、顯示與操作便利；放進 AV 櫃內也能縮短網絡線長度
同時指出只支援 Gigabit，並非 2.5Gb 或 10Gb 交換器Holzinger praises the build, display and ease of use; installing it inside AV furniture also shortened network cable runs
He notes the Gigabit limit: it is not a 2.5Gb or 10Gb switch
Kinch 在 Coincident Dynamo 膽機上使用，報告原有接地迴路嗡聲消失
他也區分器材本身的底噪，並提醒不是所有嗡聲都來自接地迴路Using it with his Coincident Dynamo valve amplifier, Kinch reports that the existing ground-loop hum disappeared
He distinguishes component self-noise and explains that not all hum comes from ground loops
在六位評論員專題中，鈴木裕以 15V 版本替換 iPhono2 原有電源，描述高頻較乾淨、低頻密度增加
亦試用於有源 USB hub，從數碼器材的供電檢視模擬播放環境In the six-reviewer feature, Suzuki replaces the iPhono2 supply with the 15V version and describes cleaner treble and denser bass
He also tests a powered USB hub, considering how digital-device supplies affect the analogue playback environment

英國音響科技品牌，專注電源、接地及器材連接中的電氣干擾，提供電源供應器、淨化器、線材與隔離產品A British audio technology brand focused on electrical interference in power, grounding and component connections, with power supplies, filters, cables and isolation products
電源噪音是電氣干擾；冷氣聲、交通聲及房間回音屬於聲學問題，AC iPurifier 2 的 ANC III 針對電源線上的 EMI／RFIMains noise is electrical interference; air-conditioning noise, traffic and room reverberation are acoustic problems, while ANC III targets EMI/RFI on the power line
它插入電源插座並以並聯方式運作，器材的供電不會串聯穿過淨化器，安裝位置及插頭版本按原廠說明選擇It plugs into a mains socket and operates in parallel; the component’s power does not pass through the purifier in series, so follow the manufacturer’s placement and plug-version guidance
光電轉換在機內完成，兩端以 RJ45 Ethernet 連接，另需 USB-C 5V DC／1A 供電Optical conversion takes place inside the unit; connect RJ45 Ethernet at each end and provide USB-C 5V DC/1A power
它處理連接中的電氣干擾路徑；光電隔離不等於修復或重新調音音樂檔案，也不代表互聯網頻寬會增加It addresses the electrical interference path in the connection; optical isolation does not repair or retune music files, or increase your internet bandwidth
嗡聲可以有不同成因，GND Defender 針對多重接地路徑形成的 DC 迴路；變壓器機械聲及其他故障需要另外判斷Hum can have different causes; GND Defender targets DC loops formed by multiple earth paths, while mechanical transformer noise and other faults need a separate diagnosis
原廠列明保留 EMI 屏蔽，偵測到故障時自動恢復接地連接，依照原廠說明及額定值使用，切勿自行移除電源接地腳The manufacturer specifies retained EMI shielding and automatic reinstatement of earth under a detected fault; follow its instructions and ratings, and never remove a mains earth pin
LAN iPurifier Pro 針對一條 Ethernet 路徑；OMNI LAN 提供多接口交換器、Ultra-Pure 區域及流量顯示，按連接數目及用途選擇LAN iPurifier Pro treats one Ethernet path; OMNI LAN adds a multiport switch, an Ultra-Pure section and bandwidth monitoring, so choose by the number and type of connections
先核對器材所需的 DC 電壓、電流、極性及接口，不能只看插頭插得進便使用；不確定時可向我們查詢Check the required DC voltage, current, polarity and connector first; a plug that fits is not enough, and our team can help with compatibility questions WhatsApp ↗
實際效果取決於原有噪音、器材設計及連接方式；先找出干擾路徑，再選相符的產品The result depends on existing noise, equipment design and connections; identify the interference path before choosing a matching product
