Overview

Audio ICs Double cassette tape recorder system preamplifier BA3423S The BA3423S is a record / playback system preamplifier for radio cassette decks.

With four control pins it allows switching between I / O for the A (play only) and B (record and play) mechanisms, input for tape, radio, and microphone, on and off switching for line out and recording output, and equalizer switching for normal and high-speed dubbing.

It requires about half the number of external components of its predecessors which means simplified assembly and overall cost savings.

Key Features

  • 1) Built-in switch for playback equalizer amplifier for the A and B mechanisms. 2) Built-in normal / high-speed equalizer switch for the playback equalizer amplifier. 3) The B mechanism input is also used as the recording output, so a switch is not required. 4) Built-in tape / radio input switch, and microphone mixing. 5) The microphone amplifier is used as the mixing amplifier, and the line can be muted to allow the built-in microphone to be used for recording.
