Vector Linear Shaping Circuitry (VLSC)

Conventional D/A conversion methods reduce digital pulse noise at the conversion stage but can’t remove it completely. Previously only found on Onkyo’s high-end components, VLSC (Vector Linear Shaping Circuitry)employs a unique D/A conversion circuit to overcome this problem. Data is converted between sampling points and these points are joined with analogue vectors in real-time to produce a smooth output wave form. The result - a virtually noiseless, smooth analogue signal based on the digital source.
