◈ Description
The S4308 is a single preamplifier IC with built-in ALC circuit, and has been designed for use in stereo radio-cassette recorders and tape recorders. The preamplifier has high gain and low distortion, and can be directly coupled to the tape head without coupling capacitors. This prevents tape head magnetization and pop noise generation. A built-in rectifier means that an ALC dynamic range can be constructed with addition of just an external time constant circuit. The IC also includes power-on mute circuits that suppress pop noise generation.
