STEREO COMPRESSOR/EQ

LF와 HF spectral side-chain control, six-band program equalizer 그리고 tube bypass를 포함한 Stereo vacuum tube opto-compressor. Stereo buss compression, audio sweetening 그리고 mastering에 최적입니다.

VT-747SP는 soft compression에서 hard knee limiting까지의 full dynamic control하는 기능을 가졌습니다. LF와 HF contour spectral control은 frequency dependent compression을 위해 side chain path를 경유할 수 있습니다. Seal된 silver relay는 모든 signal routing과 bypass function을 위해 사용됩니다.
6 band stereo program EQ는 모든 수동적인 디자인의 부드러움을 주는 100% 구별되는 Class A high-voltage transistor를 병합합니다. 단순하고 효과적인 tone control을 제안하는 동안, frequency turnover, Q 그리고 amplitude range는 자연적인 harmonic balance와 낮은 phase change를 주는 각 band에 조심스럽게 선택되었습니다. Compressor와 output driver stage에서 high-voltage dual triode tube나 amplifier를 놓음으로써, TSP(twin signal path)는 tube tone이나 classic transistor sound의 선택을 줍니다.
