The Plena table-top microphone is a stylish high quality table-top uni-directional condenser microphone, mainly intended for making calls in a PA system. Its heavy metal base and rubber feet assures a stable position on any flat surface. The special design allows, however, also for neatly flush mounting in the desk tops.

The microphone is powered by the phantom power supply of the amplifier where it is connected to. Its momentary PTT (Press-To-Talk)-key not only switches on the microphone, but also provides priority contacts, matching the Plena range of amplifiers. It is equipped with a fixed flexible 2m cable and 5-pin DIN connector for the balanced signal and the priority contacts, If no need exists for the priority contact, the microphone can also be connected to amplifiers with 3-pin XLR-input, using the DIN to XLR adapter.

A green LED indicates that the microphone is active when the PTT-key is pressed
