MOSFET switching output
Pin 4 is a MOSFET switching output to control external
devices. When the microphone is activated the output is low-
resistance to ground (< 10 Ω). In the “Remote only” mode this
output controls the microphone button. As long as this button
is pressed, the output is pulled to ground. In principle, DC
signals can be switched, the maximum current is 100 mA, the
maximum voltage is 30 V. With larger loads, the output can be
used to control an additional circuit breaker.
