■ Overview

The AN7354SC is an IC for 2 ch. Dolby B/C-Type noise reduction process. It requires fewer external parts and incorporates the functions of line-output muting and level detection and the delay circuit.

■ Features

• Built-in spectral skewing circuit not requiring external parts

• Line-output muting circuit built-in

• PB input delay circuit built-in

• Built-in level detection circuit for automatic level adjustment and level meter

• ON/OFF of NR, B-/C-type, REC./PB, MPX and muting function, and Hi/Lo changeover of level detection gain, directly-controllable by microcomputer
