BA3416BL
The BA3416BL is a dual preamplifier (for playback only) that has been designed for use with dual-cassette decks. An
internal switch is used to switch the left and right channel inputs between the A and B tape mechanisms.
The playback heads can be directly coupled to the preamplifiers without coupling capacitors, and an internal switch is
provided to switch the equalizer characteristics for metal and chrome tape.
Applications
Dual-deck stereo radio cassette players
