4. General operation
Important: Before using the handheld transmitter for the first time, you must charge the built-in battery. Please use an
appropriate Unite charger or the USB connection.
• Switch on the transmitter by pressing the on-off button .
• In order to establish an audio connection between a transmitter and one or more receivers, all devices must be paired together. See chapter 5.
• All devices are supplied with the group ID 256 and fixed audio encryption allowing quick and easy initial use. This allows a fast and easy first use, since there is no pairing required for the open group ID range between 150 and 256.
• The transmitter will only transmit the audio signal on a channel with a predefined channel name. If there are several transmitters in the group ID between 150 and 256, the channel for the respective transmitter can be selected on the receiver.
4.1 Maintenance
• Protect the handheld transmitter from humidity, knocks and shock. Avoid dropping the transmitter at all times.
• For cleaning the plastic surface of the handheld transmitter use a soft cloth moistened with a solvent-free plastic cleaner.
• As soon as your microphone sounds dull, you should clean the integrated pop shield: – Unscrew the microphone
grille anti-clockwise.

4.3 Handling
• Avoid holding the handheld transmitter at the top or bottom. You could cover the integrated antennae and therefore reduce the range. Always hold the handheld transmitter in the middle.
4.4 Microphone gain and noise suppression
• The Unite TH handheld transmitter provides various options to adjust the microphone gain and noise suppression auto­matically or manually. These options are enabled by an integrated digital signal processor (DSP).
• You will find the settings of these two DSP effects in the menu at “Audio” g “Input Effects”.
• At the factory the “ALC” (Automatic Level Control) and “Noise Canceller” are activated. If the “ALC” function is activated, the device performs an adjustment of the microphone gain to ensure that the signal is as evenly loud as possible. The result is a natural compression effect – the integrated digital signal processor (DSP) responds to the volume of the incoming signal and auto­matically increases the volume of quiet signals while limiting loud signals. This results in a very constant volume, which increases the intelligibility of speech significantly. Note: If the “ALC” function is active, the microphone gain cannot be adjusted manually any longer. The appropriate menu displays “ALC active!”.
• The “Noise Canceller” function almost completely eliminated continuously occurring background noise and attenuates punctual background noise. In contrast to the “Noise Gate” function, the “Noise Canceller” is also active when you speak into the microphone.

4.4.1 How to use the “ALC” function
• The “ALC” function provides two options: – “Near” for using the microphone close to the mouth – “Far” for using the microphone at chest height You can find both option in the menu at “Audio” g “Input Effects” g “ALC”.
• When using the “Far” setting, the “ALC” function will activate at a lower speech volume. When using the “Near” setting, you must hold the microphone at a maximum distance of 15 cm to the mouth. Furthermore, the automatic control range of the “Far” setting is higher than of the “Near” setting. This means: Due to the higher microphone gain when selecting the “Far” setting, your freedom of movement is bigger compared to the “Near” setting.
4.4.1.1 “Far” setting
• The factory setting “Far” is selected, with which you can optimally use the microphone at a distance of approx. 15 to 25 cm to the mouth (chest height). The advantage of this setting results in an arm-friendly posture and a slightly greater freedom of movement. Important: Due to the higher gain and the bigger control range loud background noise can affect the “ALC” function.

4.4.1.2 “Near” setting
• The “Near” setting is alternatively available allowing you to use the microphone closer to the mouth (below the chin). Important: In an environment with loud background noise it is useful to hold the microphone closer to the mouth so that the “ALC” function can better distinguish between speech signal and background noise.

4.4.2 Manual adjustment of the microphone gain
without using “ALC”
• If you do not want to use the “ALC” function (e.g. due to extreme background noise in your environment), you can manually reduce the microphone gain for loud speakers and increase the microphone gain for quiet speakers. In both cases use the On/Off and menu button  to access the menu at “Audio” g “Volume” g “Internal Mic”.
• If you deactivate the “ALC” function, please make sure that you keep a constant speaking distance to the mouth to achieve an optimum speech transmission.
• Avoid holding the microphone closer or further away from your mouth. Also avoid turning your head while speaking.

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 micro­phone signal and noise so that the do not work optimally.
• This is illustrated by the following example: During a sight­seeing 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” g “Input Effects” g “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” g “Input Effects” g “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.

4.6 Use as a “Sub-Master”
The Unite TH handheld transmitter can be configured in a virtual device mode (“Sub-Master”). This allows up to two additional speakers to be integrated into a device group. You will find examples for applications in the download area of the landing page: https://www.beyerdynamic.com/unite at Info materials/UNITE-USE-CASES
In the “Sub-Master” mode, the transmitter can set up an exclusive connection to a “Master” device. In one group a maximum of two “Sub-Masters” can be active. The connection between a “Sub-Master” and a “Master” device is technically the same as the connection between a Unite RP-T with activated “Talkback” function and a “Master”. The difference is that the connection between a Unite RP-T and a “Master” is temporary while the connection between a “Sub-Master” and a “Master” is permanent. In this case the audio channel is permanently open, but it can be muted by pressing the “Mute” button on the “Sub-Master”. In addition there are of course still possibilities to connect external audio sources to the “Sub­Master”. All audio signals of the “Sub-Master” are distributed via the “Master” (Broadcast) and can be routed to the “Master”. These options can be found in the “Master” menu at “Talkback” g “Audio Routing”.
Examples of up to 3 open microphones in the following device combinations:
- 1x “Master” + 2x “Sub-Master”
- 1x “Master” + 2x RP-T (Talkback )
- 1x “Master” + 1x “Sub-Master” + 1x RP-T (Talkback)
4.6.1 How to configure a “Sub-Master”
In order to configure the Unite TH transmitter as a “Sub­Master”, proceed as described below:
• Use the On/Off and menu button  to access the menu “System” g “Device Mode”.
• Select the “Sub-Master” option.
• Confirm the selected option with the On/Off and menu button .
• Restart the transmitter by pressing the On/Off and menu button .
• The transmitter reconfigures itself. This can take 1 - 2 minutes.
• You can reconfigure the device as “Master” at any time.
Note: When you configure a transmitter as a “Sub-Master” a factory setting for the “Sub-Master” will be automatically activated. This sets the value for the “ALC” function to “Far” and for the “Noise Canceller” function to “low”. This is also the factory setting for the configuration as “Master”.
