The Eartec UltraLITE UL431 HD is a wireless full-duplex intercom mix set for 4 people. It combines single-sided and double-sided headsets in one system and is suitable for teams where different workplaces have different requirements for ambient hearing and noise isolation.
In this set, the master position works with a double-sided headset, while the three Remote participants use one-sided headsets. This is practical when the central position needs to listen more concentratedly, but the other team members still need to be able to hear ambient noise. Transmitters and receivers are integrated directly into the headsets, so no separate beltpacks are required.

Questions & Answers▲
What is the difference between the Master Headset and the Remote Headsets in this set?
The Master Headset is double-sided and covers both ears, allowing for better isolation from ambient noise. The three remote headsets are one-sided so that wearers can still perceive their surroundings. This combination is suitable for teams in which the central position needs to listen more concentratedly than the other participants.
Do I need additional beltpacks or transmitters for operation?
No. Transmitter and receiver are integrated directly into the headsets. No separate belt packs or external transmitters are required, which makes the system particularly compact and easy to use.
How many people can communicate with each other at the same time?
The set is designed for 4 people. The system supports direct communication with up to 5 UltraLITE units, so that an additional unit can be added if necessary.
Do I have to press a talk button to speak?
No. The system works as a full duplex intercom without a talk button. All participants can speak and hear at the same time, similar to a normal conversation.
What range can be achieved with the system?
The specified range is up to 400 meters. However, this value depends on the operating conditions, as obstacles, building structures or other radio sources can reduce the actual range.
Which radio technology is used and is registration required?
The system uses DECT technology in the 1.9 GHz frequency range. This frequency range is registration and fee-free, so no official approval or frequency license is necessary.
How long does a battery last in operation?
With a fully charged battery pack, operation for up to 6 hours is possible. Since the batteries are replaceable, the operating time can be extended with replacement batteries.
How are the batteries charged and how many can be charged at the same time?
A 10-fold charger is included in the scope of delivery. This means that all supplied batteries can be charged at the same time, which is particularly practical between uses or after longer production days.
Can the microphone be muted?
Yes. The microphone automatically mutes when the microphone arm is folded up. A manual mute button is not required.
On which side can the headset be worn?
The microphone arm can be swiveled 270 degrees and can be worn on both the left and right. Each user can adapt the headset according to their preferences.
What is included in the scope of delivery?
The scope of delivery includes: 1 double-sided master headset, 3 single-sided remote headsets, 4 lithium batteries, a 10-fold charger and a large bag for the entire 4-person set.
What areas of application is the set suitable for?
The set is suitable for film, video and studio productions, live events, stage and event technology as well as for broadcast and streaming productions. This system is a practical solution wherever teams need to communicate with each other reliably and without hard wiring.
