Introduction

The CONFIDEA-MICL and CONFIDEA-MICS pluggable
microphones are used with the different delegate-
and chairman units. These microphones have a uni-
directional response for optimum performance even
in noisy conditions. Both types have a very low
susceptibility to interference from mobile phones.
