Cypher Labs便攜式耳機擴 驅動能力達600ohm
想出街聽歌都欣賞到媲美錄音室的音色,Cypher Lab新推出的便攜耳擴AlgoRhythm Picollo就是最佳選擇,外形輕巧迷你,只有140g重量,方便放進褲袋或手袋內。
近年高質耳機及線控耳機的普及大行其道,為了簡化生產程序各大廠家會使用 op amps來取代生產耗時的三極管,美國耳機擴音器專家Cypher Lab就不計較生產繁複,所以推出的AlgoRhythm Picollo耳擴,特別推出採用三極管作放大、獨立輸出及輸入的耳擴,輕易驅動高至600ohm阻抗的耳機。
AlgoRhythm Picollo特別用上三極管的設計,可增強耳機所需要的阻抗驅動能力達600ohm,配上不同的耳筒時可增加聆聽音樂的細緻度,使耳機傳遞出清晰通透的中高音人聲,同時提升低音的澎湃感。此外擁有獨立輸出及輸入規格,提供的輸出功率最高對應輸入5Hz-50kHz ±1dB,可優化輸出的音質,令單元驅動更流暢。
此外,內置一枚2,000mAH充電式鋰離子電池,使聆聽時間長達約最高30小時。充電使用Mini USB 5V,所以可以從電腦或USB充電器充電,靈活易用,不用擔心外出使用時突然沒電,聽得不夠盡興,隨時隨地將音樂推至最高境界。
・使用真空管:
[出力管]6L6GC×2本、[電圧増幅管]12AU7(ECC82)×2本
※出力管はEL34(6AC7)、KT88および同等管も使用可能
・定格出力:
8W+8W(6L6GC使用、UL結線時)、
8.2W+8.2W(6L6GC使用、五極管結線時)、
4W+4W(6L6GC使用、三極管結線時)
※いずれも8Ω負荷時
A modern portable amplifier with a classic circuit design. The National+ is an Opamp-less design; using 10 matched pairs of triodes in a discrete component layout. This approach to amplification delivers a robust sonic presentation that compliments a wide variety of musical styles and tastes.
The National+ housing is CNC’d from a single block of aluminum, providing exceptional protection for ‘on the go’ applications. Sized at just 3.38”x1.8”x.75”, its diminutive footprint conceals a versatile performer. Capable of pairing with sensitive earphones when in ‘low gain’ it is also capable of driving planar magnetic headphones while in its ‘high gain’ setting.
The easy to use National+ features a 3.5mm single-ended input and output. This offers a simple solution to amplify your portable high resolution digital audio player or the sensitive low level signal from your favorite DAC. Its output provides 3 gain stages to provide the perfect match for an audiophile’s earphones and/or headphones.
Carrying case, USB cable for charging and ALO audio amp straps included with The National+.
