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 a USB connection.
• Switch on the transmitter by pressing the on-off button 4.
• 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 pairingrequired 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 1 anti-clockwise.– Pull out the foam pop shield, if necessary use tweezers.– Clean it under clear running water.– If necessary, use a mild washing-up liquid.– Dry it afterward with a hairdryer or allow it to dry overnight.– Clean the microphone grille both inside and out with a slightly moistened cloth or a soft brush under clear running water and allow it to dry overnight.– The microphone grille cannot be cleaned in a dishwasher.– Place the dry pop shield inside the microphone grille and replace the microphone grille by screwing it on clockwise.

4.2 How to replace the colored ring

• Press the colored ring with two fingers slightly together, grab the small loop and pull the colored ring carefully from the transmitter.
• Slide the new colored ring from the bottom onto the transmitter.Make sure that the colored ring is not twisted.

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 auto- matically 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 attenuated 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 heightYou can find both options 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 that 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 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 loudspeakers and increase the microphone gain for quiet speakers. In both cases use the On/Off and menu button 4 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 that 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 they 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 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 playbackYou 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-CASESIn 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 an 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 “Sub-Master”, proceed as described below:

• Use the On/Off and menu button 4 to access the menu “System” g “Device Mode”.
• Select the “Sub-Master” option.
• Confirm the selected option with the On/Off and menu button 4.
• Restart the transmitter by pressing the On/Off and menu button 4.
• 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”.4.6.2 How to connect a “Sub-Master” to a “Master”In order to connect a “Sub-Master” to a “Master”, you have to perform a channel search. Please proceed as described below:

• Press the or symbol of the multifunction button 5 and start the dynamic channel search.
• The basic conditions to establish a connection must be guaranteed (refer to chapter “Pairing information”).Alternatively, you can transmit the pairing information via a charger. As a “Sub-Master”, the transmitter will receive the channel name, group ID, and audio encryption key from the charger like a Unite RP or RP-T.

4.7 How to use with a Unite AP4 access pointIn conjunction with a Unite AP4 access point, the Unite TH can be used as a wireless microphone. In order to establish a connection to a Unite AP4, the Unite TH must be configured as “AP4 Mic (Sub-Master)” via the menu. This model is technically equivalent to a “Sub-Master”, which can establish an exclusive connection to a “Master” (Unite AP4).4.7.1 How to configure as “AP4 Mic (Sub-Master)”

• In order to configure the Unite TH in the “Sub-Master” mode, select in the menu “System” g “Device Mode” g “AP4 Mic (Sub-Master)”.
• Confirm the selected option with the On/Off and menu button 4.
• Restart the transmitter by pressing the On/Off and menu button 4.
• The transmitter reconfigures itself. This can take 1 – 2 minutes.
• You can reconfigure the device as “Master” at any time.

4.7.2 How to connect to a Unite AP4 Master

• In order to use the Unite TH as a wireless microphone with a Unite AP4, you must perform a channel search.
• Press the or symbol of the function button on the Unite TH to start the dynamic channel search. The basic conditions to establish a connection must be guaranteed (refer to chapter “Pairing information”).
• The second way to establish a connection between the Unite TH and Unite AP4 is to use the Unite Manager PC software for pairing. Please refer to the Unite Manager PC software manual.

Pairing information

In order to communicate with each other, the transmitter and receivers must have the same encryption key, group ID, and channel name. Only then they can communicate with each other. There will be no communication with receivers that do not have the same pairing information. This is illustrated in the figure below.

5.1 EncryptionThe audio data is always encrypted with an AES-256 code to ensure secure transmission.The required key will be generated within the charging unit itself or via the Unite Manager PC software and transmitted to the transmitters and receivers during the pairing process.As the key is not transmitted via radio, the system is even better protected against eavesdropping.Should the receiver receive a different encrypted audio signal for which no key has been saved, the received audio signal will be muted. The receiver display will also alternate between showing the relevant channel name and the “KEY!” error message.The encryption of the audio signal is shown schematically in the following diagram.

Note: The group IDs in the range of 150 to 256 uses a factory-defined key that cannot be changed. You can use this group ID for a system without pairing.5.2 Group IDThe group ID refers to devices that can be combined into a virtual group. For example, all devices of a building, a travel group, or a conference room.Use with the group ID 150 – 256By default, the transmitters and receivers are supplied with group ID 256.A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256. Due to the factory-set audio encryption key, the devices within the group ID range of 150 to 256 can connect to each other without pairing via the charger. In this case, receivers can connect to transmitters via the dynamic channel search.Example: Via the dynamic channel search, a receiver that is set to the group ID 160 will find all transmitters which are active and also set to the group ID 160. The receiver can connect to a transmitter without pairing. The receiver will not find transmitters beyond the set group ID range of 160.Attention: When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at the same time, make sure that the individual channel names differ from each other! Otherwise, this can cause connection problems with the receivers!Use with the individual group ID 1 – 149If several receivers are to be divided into different groups with individual encryption, for each group an individual group ID between 1 and 149 can be assigned. A separate audio encryption key is generated for an individual group ID in order to ensure additional security against unauthorized listening during the wireless transmission. This audio encryption key is generated during the pairing process, stored in the charger, and transmitted from the charger to the transmitter and receiver, along with the channel name and group ID. The receivers can only connect to a transmitter with which they have been paired via the charger. If the group ID is subsequently set manually on a receiver that has not been paired, no connection can be established to the transmitter with the encrypted group ID, because the receiver does not have the audio encryption key (refer to chapter “Encryption”).How to change the group ID

• Press and hold the menu button 4 for 2 seconds to activate the main menu.
• Use the multifunction button 4 to select “System” from the menu.
• Press the menu button 4 to open the required submenu.
• Use the multifunction button 4 to select the “Group ID” submenu.
• Press the menu button 4 to set a group ID.
• Use the multifunction button 4 to select the desired group ID.
• Press the menu button 4 to confirm the selected group ID.

Make sure to select the same group ID for all devices of the desired group. Only devices that have the same group ID can communicate with each other. Transmitters with other group IDs are hidden. See the following diagram.

5.3 Set channel nameDevices that are grouped with one group ID can transmitmultiple audio channels via the same group ID.In order to differentiate between audio channels from severaltransmitters on the receiver, enter a five-digit name for thechannel on the transmitter. Proceed as described in thefollowing:

• Hold down the menu button 4 on the transmitter for more than 2 seconds to activate the main menu.
• Use the multifunction button 5 to select “System” from the menu.
• Press the menu button 4 to open the required submenu.
• Use the multifunction button 5 to select the “Channel Name” submenu.
• Press the menu button 4 to set the channel name.
• Use the multifunction button 5to scroll through the characters. When the desired character appears, confirm using the menu button 4. You can input max. fivecharacters.
• As soon as you select the configured transmitter on the receiver, the defined name will be displayed on the receiver’s display.
• The following diagram shows an example of two transmitters with different channel names, and a receiver that can find and switch between both transmitters. Finding and/or switching between channels can take several seconds.
• Change the channel on the receiver via the dynamic channel search. Press the p or q symbol of the channel buttons and confirm the displayed “Scan for channels?”question with “Yes” by pressing the menu button. Depending on the DECT environment and the distance to the transmitter, it may take several seconds to find the channels.
• Press the or symbol of the channel buttons to select the transmitter (channel name). In order to confirm press the On/Off and menu button 4.Note: Once the channel search is started, the receiver will lose its connection to the previous transmitter.

5.4 How to create a pairingThere are three different ways to pair the Unite transmitters with receivers:

1. Via an individual charger.
2. Using the Unite Manager Software on a PC.
3. Via dynamic channel search.

If you want to use a group ID of the individual encryption range 1 to 149, you must perform a pairing with a charger or the Unite Manager PC software.You will find detailed descriptions in the Quick Start Guide of the appropriate charger, in the Unite Manager PC software manual, and in the comprehensive system manual on the internet at www.beyerdynamic.com/Unite
