Dual-channel, auto-reverse tape preamplifier
The BA3402 is a dual preamplifier developed for auto-reverse car tape decks. An electronic switch on the chip switches between the forward and reverse heads, and this has the benefits of greater reliability, easier wiring, lower space requirements, and improved assembly efficiency when pared with conventional mechanical switches. The circuit is designed in such a way that coupling capacitors are not required. In addition to reducing the number of external ponents required, this ensures that the head is not magnetized when the power is applied.
