Figure 3. ACC2 Module
The ACC2 Module, shown in Figure 3, is a 2.5mm phone plug to phono plus 3.5mm mono jack module. It is
useful in station applications with an external linear amplifier, where the phono jack outputs the active-low
KEY OUT signal used to place the amplifier into transmit mode. The 3.5mm phone jack functionality is
determined by the ACC2 IO menu item in the KX3's menu. It may be configured as either AuxBus (for use with
the KRC2 controller), Push-to-Talk (PTT) input (active-low or active-high), or transmit inhibit (active-low or
active-high). See the KX3 Owner's Manual for details.
