Future-proof, license-free audio transmission

SpeechLine Digital Wireless operates in the future-proof 1.9

GHz frequency band. Transmission in this band is not affected

by regulatory changes of the digital dividend or by the auction

ing of frequencies. In addition, the frequencies in this band can

be used without a license. With SpeechLine Digital Wireless,

you don't have to fear changes to the frequency band used

which could possibly mean having to buy new audio equip

ment. The acquisition of a SpeechLine Digital Wireless system

is a future-proof investment.

To allow optimum use of the 1.9 GHz frequency band, Speech

Line Digital Wireless offers two operating modes: For up to

20* links used in parallel, the

Adaptive Power Mode

ensures

extremely easy startup and a reliable maximum range. The

Multi-Room Mode

allows you to adjust the transmission pow

er to allow for a considerably larger number of links. These ad

justment options make SpeechLine Digital Wireless the

optimum solution for a great variety of projects with widely

differing installation sizes at the same location.

Tap-proof audio transmission

The encrypted, tap-proof transmission of information is espe

cially important in the corporate environment. This is why we

decided to use 265-bit AES encryption when developing the

SpeechLine Digital Wireless series. Here the security of wire

less transmission is ensured by the generation of a new key

each time a new connection is made between transmitter and

receiver. At every meeting and every conference, this guaran

tees that only the receiver paired with the transmitter is able

to decode the audio signal. Encryption cannot be deactivated

– making SpeechLine Digital Wireless secure at all times.

Extremely long battery life

It is not necessary to replace or recharge the accupack during

operation. The battery life is about 15 hours – enough for even

a very long conference day. Intelligent energy management

using adaptive transmission power maximizes the battery life.

To charge the accupacks, it is not necessary to remove them

from the transmitters. They can be recharged using the op

tional CHG 2 charger for handheld and pocket transmitters or

directly via the supplied USB charging cable.
