Automatic frequency management
SpeechLine Digital Wireless finds free transmission frequen -
cies reliably and fully automatically. Manual intervention is not
necessary in the search for a free frequency. This means that
your wireless microphone and the receiver 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 immediately 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 possi -
ble 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 microphone used, and the audio level is automatically ad -
justed for different speakers. In addition, different sound pro -
files are defined for male and female 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 adjust -
ed so that the speaker's voice can be heard loud and clear. If
necessary, the receiver's output level can be manually adapt -
ed 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 chang -
ing the frequency. This prevents interference and audio drop -
outs and ensures an uninterrupted connection. 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 au -
tomatically selected so that they cannot interfere with each
other. The frequencies are immediately adapted to newly add -
ed radio links without interfering with the ongoing transmis -
sion or even interrupting it.
