Dual preamplifier with mute function
BA3406AF
The BA3406AF is a multi-function dual-channel preamplifier with a built-in mute circuit and a time-constant switching
circuit for use with metal tape. The output circuits have diodes, and can be connected to other circuits in parallel, which
eliminates the need for switches. The mute circuit is independent of the preamplifier block, and can be used to mute the
whole system.
