invidis consulting GmbH, headquartered in Munich, Germany, is a renowned European consulting firm for digital signage. One of the strategic objectives of this specialized consultancy is to strengthen its own position as the leading information provider for digital signage in Europe. As a way to achieve this, the company provided a tour of signage at the Integrated Systems Europe (ISE) tradeshow.

Trade shows typically have loud background noise, and ISE was no exception. Therefore, guiding a tour on the show floor and ensuring everyone could hear the speaker was a challenge. The invidis consulting firm chose the Listen LT-700 Portable Display RF Transmitter to wirelessly broadcast audio to everyone in the group without having to carry a microphone or be plugged into a wall. The LT-700 is excellent for factory tours, outdoor events, wireless microphone applications, classrooms, training, or personal use – anywhere there is a need to amplify sound, but without an installed system.
