SpeechLine Digital Wireless is the first digital wireless microphone system designed specifically for the spoken word. SpeechLine Digital Wireless is a future-proof solution that’s easy to set up, use and manage and that lets the presenter concentrate on their words, not on the technology. SpeechLine Digital Wireless comprises mobile transmitters (handheld or bodypack) tailored for speech applications, speech optimized condenser microphones (a microphone capsule for the handheld transmitter, a clip-on or headset microphone for the bodypack transmitter) and a rack receiver. The transmitters are powered by rechargeable lithium-ion accupacks with a battery life of more than 15 hours. The accupacks can be recharged with the charger or via USB. SpeechLine Digital Wireless has an automatic frequency management feature that automatically searches for free frequencies on site, thus eliminating the need for time-consuming frequency planning in advance. In addition, the automatic interference management function always ensures a stable wireless connection, and thus provides maximum transmission reliability. The automatic microphone sensitivity adjustment makes the setup even more convenient since there is no need for manual level adjustment. What is more, network integration enables SpeechLine Digital Wireless to be remote controlled and monitored using a media control system (e.g. AMX, Crestron) or the browser-based Sennheiser Control Cockpit software
