The BA3311L is a dual preamplifier with ALC designed for use in stereo radio-cassette recorders. It comes in a compact 12-pin ZIP package and has two record/ playback preamplifiers, and an ALC circuit. The preamplifiers are directly coupled to the head and do not require coupling capacitors. This prevents tape head magnetization and "pop" noise generation.
An ALC circuit with large dynamic range can be constructed with addition of just an external detector and time constant circuit.
