MURAKUMO BNC Cable (50Ω)

MURAKUMO BNC-50ケーブルは外部マスタークロック、主に10MHz入出力で用いられる 50Ω用BNCケーブルのコンセプトシリーズに位置します。

セシウム・ルビジウム原子時計・GPS等の超高精度クロックから、 オーディオ用マスタークロック機器への接続を想定し設計いたしました。 高周波仕様の50Ω入出力で設計された機材には、50Ωで設計したケーブルを使用する事は より高い精度と、更に高い音質を得る為には極めて重要です。

ハイエンドデジタル機器のClockでは75Ωでの入出力と50Ω入出力が混在しています。 デジタル機材を束ねるクロックはシステムの根幹であり、その入出力は適切な インピーダンスに対応したケーブルで接続することが極めて重要(※1)だと考えております。 Briseaudioでは75Ωタイプと50Ωタイプをそれぞれご用意しております。

高い精度と的確なインピーダンス整合は勿論の事、 ハイエンドオーディオ向けクロックケーブルに求められる性能を限界まで追い求めつつ、 長年に渡る研究成果をコスト度外視ですべて投入し完成いたしました。 Briseaudioの考える究極の50Ω専用BNCケーブルです。

高い解像度と膨大な情報量、そして極めて低く抑えられたノイズフロアによる 息を呑むような静寂からの音の立ち上がり、 音の消え際まで余すことなく立体感を持って描き切ります。

The basic structure is a high-frequency coaxial structure, and high-purity single copper wire is used as the conductor. High-firing polyethylene resin is used for insulation, and a combination of copper foil tape and copper braided shielding material is used for high-frequency waves in the GHz range. The conductor is insulated with highly foamed polyethylene resin, and is combined with copper foil tape and copper braided shield material, which are highly effective for high frequencies up to GHz.

The cable itself generates micro vibrations and vibrations from the outside world are effectively attenuated by a combination of special materials. The combination of several special materials effectively attenuates the vibration and greatly reduces its impact on sound quality. This has succeeded in greatly reducing the impact on sound quality.

In addition, by combining several special materials that are effective in different bandwidths natural extension of the high frequency range and a high quality feel are achieved.

One of the features of the MURAKUMO series is the use of One of the features of the MURAKUMO series is the luxurious use of multiple layers of broadband non-magnetic special laminated electromagnetic wave absorbing material, an extremely expensive The MURAKUMO series is characterized by the luxurious use of multiple layers of a special broadband non-magnetic laminated electromagnetic wave absorber, an extremely expensive material that is currently unavailable. This gives the MURAKUMO series overwhelming shielding performance. Furthermore, by effectively arranging various different materials This material provides not only shielding performance, but also extremely good sound quality in terms of audibility.

Clock cables that exert a great influence on the sound image and focus. The unparalleled low noise floor level is unparalleled. The fusion of audio pleasure and music that results from this is the hallmark of the MURAKUMO series.

The standard terminals are gold-plated pin-type 50Ω high-frequency dedicated BNC plugs. A copper alloy housing and Teflon insulator are used to ensure both high safety and smooth connection. Furthermore, a special material is placed on the outside of the terminal to give priority to sound quality.

MURAKUMO, our concept series, has been developed specifically for use in ultra high-end audio systems.  MURAKUMO was developed specifically for ultra high-end audio system applications.  Therefore, it requires a very high resolution for audio systems including the environment.  The MASAMUNE series (our reference series) is a model that achieves sound quality approaching that of the MURAKUMO series in many more environments.  MASAMUNE series (our reference series).

*1  When 75Ω cable is used for 50Ω input/output terminals, reflection and radiation occur at the terminals at high frequencies  This phenomenon can interfere with signal transmission.  This is usually not a major problem in the length of cables used for audio equipment.  However, the longer the distance, the more the signal overlaps, which can interfere with transmission and damage the equipment.  This phenomenon can become serious enough to interfere with transmission and damage the equipment.  In order to fully demonstrate the performance of high-end audio equipment  Impedance must be matched (equalized) in order to fully demonstrate the performance of high-end audio equipment.

*This is a basic structure diagram of the MURAKUMO series. Arrangements are made according to cable types and sound quality trends.
