由線材起家,ALO在音響的生意近年越做越大,耳擴方面也有不錯的成績。便攜耳擴的系列繼The National、The Continental後,繼續以地域來命名,新機稱作The International,同時擁有DAC及耳擴功能。機身同樣走輕巧路線,擁有USB DAC,最高對應24bit/96kHz,芯片用上Cirrus Logic CS4398,模擬方面對應3.5mm Line-in及4針平衡輸入,輸出亦同樣備有方型4芯平衡輸出及3.5mm耳機輸出。平衡線路方面用上Burr Brown DRV134作放大處理,輸出作面備有3段Gain設定。耳擴在充電後可使用14-16小時,如果連同DAC功能使用,續航時間為8-10小時,擁有不俗的續航力。
解碼晶片採用CS4398, 支持24/96
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+.
