What are the features of SpeechLine Digital Wire-
less?
Automatic frequency management
SpeechLine Digital Wireless finds free transmission frequencies reliably
and fully automatically. Manual intervention is not necessary in the search
for a free frequency. This means that your wireless microphone and the re-
ceiver are ready for use within an extremely short time: connect them,
switch them on – and that's all.
The transmitter and the receiver are pre-paired at the factory and immedi-
ately work together. If necessary, this pairing can be changed at any time,
for example in order to switch from a clip-on microphone to a handheld
transmitter. It is also possible to use several transmitters, such as when
each lecturer at a university uses their own microphone.
Automatic microphone sensitivity adjustment
It is not necessary to manually adapt the input sensitivity to the micro-
phone used, and the audio level is automatically adjusted for different
speakers. In addition, different sound profiles are defined for male and fe-
male voices. In this way, the high-quality microphones of the SpeechLine
Digital Wireless series can unleash their full potential without distortion.
Automatic level management
The level of the audio signal is automatically optimally adjusted so that the
speaker's voice can be heard loud and clear. If necessary, the receiver's
output level can be manually adapted to the input of the mixing console or
amplifier.
Automatic interference management
The system immediately reacts to interfering signals such as those coming
from DECT telephones by automatically changing the frequency. This pre-
vents interference and audio dropouts and ensures an uninterrupted con-
nection. The automatic frequency change is not noticed by the user of the
microphone or by the audience. If several radio links are active for different
speakers at the same time, the respective frequencies are automatically
selected so that they cannot interfere with each other. The frequencies are
immediately adapted to newly added radio links without interfering with
the ongoing transmission or even interrupting it.
Future-proof, license-free audio transmission
SpeechLine Digital Wireless operates in the future-proof 1.9 GHz frequen-
cy band. Transmission in this band is not affected by regulatory changes of
the digital dividend or by the auctioning of frequencies. In addition, the fre-
quencies in this band can be used without a license. With SpeechLine Dig-
ital Wireless, you don't have to fear changes to the frequency band used
which could possibly mean having to buy new audio equipment. The acqui-
sition of a SpeechLine Digital Wireless system is a future-proof invest-
ment.
To allow optimum use of the 1.9 GHz frequency band, SpeechLine Digital
Wireless offers two operating modes: For up to 20* links used in parallel,
