. 자작해서 맹글어 사용해 보았지만...... 리모콘은 어렵더라구.디자인은 말끔한 것이 마음에 들고 투명창이 있어서 일단 돌고있는 것이 보이니까 재미있고 해서 구입.

음질은 프랜스포트로만 사용하려고 중요시 여기지 않았슴. 광포트 1, 알씨에이 포트 1, 디지탈포트 1

단지 흠이라면 110전용이라 다운 트랜스를 사용한다는것 요게 조금 지저분해요.

디지탈의 데이타를 아날로그 신호로 바꾸어주는 기계다. 주요 부품은 메이드인 자판임. 그러니까 국내 기업육성이 필요한 것이고 국내투자자들은 당투기 하는것인가.

Application Recommendations
Single-input Loudspeakers:
8VS gray wires positive, black wires negative.
Bi-wire Loudspeakers:
4VS/8VS bi-wire 4VS for "HIGH" post and 8VS for "LOW" post.
Sub-woofers:
8VS ?brown wires positive, black wires negative. 8VS Double Run ?one combined 8VS for positive and one combined 8VS for negative. A double run combination will increase low frequency impact and extension.
General Specifications:

Available Lengths: 1 foot to 250 feet in 1 foot increments (0.5 meter to 75 meters in 0.5 meter increments). 
General Specifications:
Eight gray wires = positive (+). Eight black wires = negative (-)
Aggregate wire sizer:2 x 9AWG  
Cable geometry KIMBER KABLE original large format braid. Wire geometry:
VariStrand 

Conducting medium is our Ultra-pure copper (Cu).
Insulation (dielectric) is polyethylene.
Dielectric tested at 1,500 volts.
RF/EMI shielding method electrodynamic/geometric.
RF/EMI rejection extremely high.
Cable diameter 13/32 (10.2mm).

8VS is perfectly suited for subwoofers and for the low frequency section of bi-wire formatted speakers..

  • Decrease noise and signal distortion. Increase in system dynamics and fidelity due in part to the dramatic reduction of radio frequency (RF) interference. This is accomplished through the correct implementation of our time proven KIMBER KABLE braiding technology.
  • Increased resolution when compared to our 8PR due impart to the refined Ultra-pure copper conductor and VariStrand wire geometry.
  • Decreased internal noise resulting in increased transparency, attributable to refinements in the wire and insulation.
  • Very fast and agile due again mainly to our braiding technology, whichreduces, loop inductance better than any other cable.
  • Accuracy surpassing nearly all other loudspeaker cables. This is the result of how we orient the conductors within the braid in relation to each other and the quality of materials used. The steep angle of incident between conductors assists in the preservation of the original signal.
  • May be ran for very long (100 feet plus) distances inside or next to metal surfaces without induced distortions.

 

  • 개인적으로 한국 오디오 플러스사의 울림통 연결줄도 훌륭한제품으로 가격대비 성능이 뛰어나다고 생각함.
