Table top units

Introduction

The contribution units consist of delegate and chairman units. Both are used for speech reinforcement in a conference room. The chairman units are used to guide and control an ongoing discussion. There are two types of units available: units with a fixed microphone and units with a screw lock microphone (SL). You can use both units interchangeably, meaning that your setup can be a mix of both types.
