美國 HARMONIC TECH 全新推出唱臂專用訊號線 ~ LP-10 登場

由唱臂到唱頭放大器的訊號線(PHONO CABLE) 與一般的訊號線其實在導體及結構的設計上均有很大分別，背後亦蘊藏了很大的學問。

唱頭的發聲原理是靠唱針接觸唱片內槽產生震動再透過唱頭內線圈產生的電流, 形成純正的類比音樂信號. 由於信號極度微弱, 一般訊號線較粗的導體難以傳送這種微弱的信號, 有可能造成信號大量流失, 所以唱臂專用訊號的導體都會選用比較幼細AWG24-26 號的導體以減少訊號傳送的流失。

另一個重要因素是導體與導體之間的絕緣體材質所造成的電感值, 一般訊號線的絕緣體會採用PVC, PE 等材料, 這類材料電感值較大, 同樣會影響信號的傳送. 最理想是低電感值的材料首選當然是空氣, 但空氣不能用來做絕緣物料, 故此LP-10 的絕緣物料使用特富龍(TEFLON), 它是空氣以外電感值最低的絕緣物料, 非常適合用在唱臂線上使用。

除了電感效應的因素外, 屏蔽層的設計亦是另一個相當重要的因素, LP-10 採用了黃酮箔加上用高純度無酸銅網作為屏蔽層, 達到99.9% 的遮蔽作用, 大大減少了外界的電磁波對信號傳送的干擾。另外導體的正負導線使用45度角絞合的設計, 令正負磁場不會互相干擾, 有利微弱的信號傳送。

在黑膠的世界, 不同的唱臂不同的唱頭都有他本身獨有的音色, LP-10唱臂線在校聲上, 特別強調真實的類比還原度及表現力兩方面, 聲音取向非常中性自然, 沒有音染, 能夠有效表現出用家自身的唱臂以及唱頭還有的類比音色, 表演出有生命力的音樂。

Description:

Introducing the LP-10, the new specialized signal cable for tonearms by HARMONIC TECH from the United States.

The design and construction of a signal cable for the connection between a tonearm and a phono preamp differ significantly from regular signal cables.

There is a great deal of expertise involved in this process. The principle of a cartridge relies on the contact of the stylus with the grooves of the record, which generates vibrations. These vibrations are then converted into an analog electrical signal by the cartridge’s internal coils. Due to the extremely weak nature of the signal, standard cables with thicker conductors struggle to transmit such delicate signals, leading to potential signal loss. Therefore, specialized tonearm cables use finer conductors, typically AWG 24-26, to minimize signal loss during transmission.

Another important factor is the electrical inductance caused by the insulating material between conductors. Regular signal cables often employ PVC or PE materials, which have higher inductance values that can impact signal transmission. The ideal choice for minimizing inductance is air, but since air cannot be used as an insulating material, the LP-10 utilizes Teflon, which has the lowest inductance value among insulating materials other than air. Teflon is well-suited for use in tonearm cables.

In addition to the effects of inductance, the design of the shielding layer is another crucial factor. The LP-10 incorporates a combination of Mylar foil and high-purity acid-free copper mesh as its shielding layer, achieving 99.9% shielding effectiveness and greatly reducing interference from external electromagnetic waves. Furthermore, the positive and negative conductors are twisted together at a 45-degree angle to minimize mutual interference of magnetic fields, facilitating the transmission of weak signals.

In the world of vinyl records, different tonearms and cartridges possess their unique sonic characteristics. The LP-10 tonearm cable, in terms of sound tuning, emphasizes both the authenticity of analog reproduction and expressive capabilities. The sound signature is neutral and natural, devoid of coloration, effectively showcasing the inherent analog tonal qualities of the user’s tonearm and cartridge, ultimately delivering vibrant and lifelike musical performances.
