The APM116 MK2 is a 16-zone digital PA microphone equipped with a cardioid-grade condenser element mounted on a 30cm gooseneck. By means of a built-in compressor/limiter, the microphone signal output level is constantly maintained. The status of the reproduced signal is indicated on the front panel, to assure the speaker that the message is clear and audible in all situations. The console has 16 zone selection buttons and three standard buttons with pre-assigned functions: PTT (Push To Talk), select all and delete. Functions can be freely programmed using the APM configuration software.

The status of the reproduced signal is indicated by different LEDs on the base of the microphone, indicating to the speaker that the signal is clear and audible in all situations. Each console contains three standard buttons (except the APM101MK2 which only has PTT) with pre-assigned functions: PTT (Push To Talk), Select All and Clear All. The other function buttons can be configured to make announcements to particular zones, group zones, or other functions. (relay activation and switching, voice file announcements.
