Speech Line Digital Wireless is a presentation solution dedicated to speech. The digital wireless microphone system is a future-proof solution that's easy to set up, use and manage. A microphone which lets the presenter concentrate on their words, not on the technology.

SpeechLine Digital Wireless comprises of mobile transmitters (handheld or bodypack) tailored for presentation, speech optimized microphone capsules (condenser capsules, lavalier or headworn microphone)and an easy-to-integrate stationary receiver. For convenience,the system relies on lithium-ion technology with a battery lifetime of more than 15 h and flexible charging solutions of multi-device chargers or USB-charging on the fly. Thanks to the Automatic Frequency Management, the system always finds a free frequency (no frequency planning is necessary anymore). The Automatic Interference Management always maintains a stable connection, which makes the system very reliable. The Automatic Sensitivity Management makes the setup even more convenient, no more gain settings are required.

With seamless network integration the system can be controlled via AMX, Crestron or a dedicated remote control software, which makes SpeechLine DW easy to monitor and to manage.

For secure communication, SpeechLine Digital Wireless uses the secure advanced 256-bit AES encryption for secure wireless transmission. Due to the 1.9 GHz frequency range SpeechLine DW is the future proof investment and already DD ready. Moreover, the 1.9 GHz is license free and requires no registration.

The sleek but robust SL Handheld DW is optimized for speech in presentations or lectures where every word matters.

The SL Handheld Set includes the handheld transmitter, stationary receiver and everything to use or install. It comes wiht the MME 865 condensor capsule - so not just a capsule, but the best capsule for speech.

All sets also come with rechargeable accupacks with up to 15 hrs of operating time. The accupack is also USB rechargeable, the cable is in the box, the USB socket is presumably just a step away from you.

The two types of sets are either Rackmount Sets (-R version), which come with everything needed for rack mounting, or Case Sets (-C version), in a transport case - without rackmounts, if you do not want to install the receiver.
