K DAC

     

為什麼叫K DAC?

K來自Key這個詞。在音樂中，Key代表調性。我們常說的C大調白色，E大調黃色，
a小調純藍色。Key非常影響音樂的色彩。
在音樂中，Key也用於代表某個調式的主音。這也符合我對解碼器（DAC）在音響系統中的定位。 我一向認為，音響系統中，解碼器（DAC）是決定整個系統上限的最關鍵音素。 就好像大師手中的那把Stradivari名琴,沒有那把Stradivari名琴，再好的錄音和回放都失去靈魂。

K DAC是桌面小型系統的核心，是Key Point, 是關鍵。
XIAUDIO從丹麥Soekris定制R-2R解碼核心，展現XIAUDIO的音樂美學和來自丹麥的成熟技術。 可以直接推動主動式喇叭，或組成小型的頂級水準耳機系統。
K DAC可以攜帶移動。追求極端的發燒友甚至可以用電池直接供電。
K DAC採用了數字電源和線性電源組合的方式組成供電系統。共9個供電電路給各部分分別供電。

What is a K DAC?

In music theory, the key is a group of pitches, or scale, around which a piece of music revolves. Key is tonality, and relates to the color and emotion of the music. For example, the key C major is white, innocent and pure, E major is orange, warm and energetic, and A minor is turquoise, gentle soothing sadness like a rainy day.

K DAC is the key point, it’s the core of an audio system. XIAUDIO uses a custom R-2R ladder developed exclusively for them by Soekris of Denmark. This method of digital to analog audio conversion has become quite popular in high-performance audio, particularly with more critical headphone systems where the ability to listen to music in a highly linear fashion is key. Subtle nuances between shades of tonal colors simply flow and more accurately define the artists emotional intent hidden within.

Music flows smoothly from this K DAC with the beauty of a very finely tuned instrument, maintaining live harmonic structure and vocals in a way XIAUDIO products are so well known for. K DAC reproduces the delicate nuances in your music like no other near this price point.

For headphone listeners, combine the K DAC with their matching Broadway Balanced headphone amplifier for a dynamic and powerful musical presentation for one.

KDAC可以外接直流線性電源供電。供電規格要求：12~15VDC，1.0~2.0A。

插頭規格：標準型號是DC005或DC050，插頭外徑5.5mm, 內徑相容2.1~2.5mm。

注意，KDAC外接線電的話，線電的DC輸出（無論是正端還是負端）絕對不能接地，要懸浮。這里的地是指220VAC或110VAC排插的中心腳地線。
