The Plena tabletop microphone is a stylish, high-
quality tabletop unidirectional condenser microphone,
mainly intended for making calls in a public address
system. Its heavy metal base and rubber feet ensure
stability on any flat surface. The special design also
allows the unit to be neatly flush-mounted in desktops.
Functions
The PTT-key (press-to-talk), not only switches on the
microphone, but also provides priority contacts, that
are compatible with the Plena range of amplifiers. The
switching characteristic of the PTT-key can be
configured internally for PTT-mode (on as long as
pressed) or toggle-mode (press to switch on, press
again to switch off).
It is equipped with a fixed, flexible 2 m cable and a
5‑pin DIN connector for the balanced signal and the
priority contacts. If the priority contacts are not
required, the microphone can be connected to
amplifiers with 3‑pin XLR-inputs, using the DIN to XLR
adapter.
A green LED indicates when the microphone is active.
