4.4.3 Compressor and Noise Gate
• The "ALC" and "Noise Canceller" functions are intelligent DSP
algorithms which react to an incoming signal. If very loud
and various background noise occurs in your environment,
the algorithms can no longer distinguish between micro-
phone signal and noise so that the do not work optimally.
• This is illustrated by the following example: During a sight-
seeing tour on the upper floor of an open bus, a strong
airflow occurs and enters the microphone capsule. The DSP
algorithms "ALC" and "Noise Canceller" can not distinguish
between airflow and speech signal.
• For such situations a compressor is available in addition to
the automatic control of the microphone gain ("ALC"). You
will find this function in the menu at "Audio"
"Compressor".
The compressor statically increases the volume of soft
speech signals.
The following options are available:
"low" = compression 2:1
"high" = compression 4:1
"less pop noise" = relatively high degree of compression to
contain explosive sound
• In addition to this you can the "Noise Gate" function instead
of the intelligent "Noise Canceller". The "Noise Gate" starts to
work at a defined threshold and eliminates background
noise during pauses in speech.
• You will find this function in the menu at "Audio"
Effects" "Noise Gate".
4.5 Bluetooth® interface
• The Bluetooth® function of the handheld transmitter is used
as an audio interface for the following applications.
1. For the use with a Bluetooth® headphones
(Use of the Talkback functionality)
Since the Unite TH does not have a headphone output,
you can connect a headphone via Bluetooth®. This allows
listening to the talkback signals of the Unite RP-T receiver
and "Sub-Master" devices.
2. For playback
You can also use the Bluetooth® function to playback
audio signals from external sources (e.g. smartphones
or computers).
Tip: If Bluetooth® is used for the playback of external
audio sources, we recommend using the DSP effect
"Ducker". The "Ducker" decreases the signal of an external
audio source as soon as someone is speaking into the
microphone capsule ensuring optimal speech intelligibility.
You will find a detailed description of the use of the Bluetooth®
function in the comprehensive "Unite" system manual on the
internet at www.beyerdynamic.com/unite.
