The self-contained, all-in-one design in this master headset eliminates wires and belt-worn radios by placing the transceiver in the earcup. This allows the headphone to provide two-way voice communication for users that need to work with their hands. The mic boom arm swivels 270° so the mic can be worn on the left or right. The microphone mutes when in the up position.

The UltraPAK is an ergonomic beltpack radio that can be integrated into Eartec's UltraLITE full-duplex wireless series. These compact digital transceivers have been designed specifically for those users that need hands-free voice communication and also require a lightweight, headset accessory. UltraPAK transceivers weigh only 2.5 oz and feature an ergonomic design, so they fit comfortably when belt worn. They include 5 volume control adjustments and a mic mute button with an LED indicator that illuminates when gain is set to standby.

Monarch dual-ear headsets are comfortable, rugged, and cost effective. They feature a slender back band manufactured with BPT—the same plastic material used to make automobile numbers—so they are right at home in rough and tumble industrial environments. The comfortable foam padded speakers sit on, not over the ear, which allows users to monitor the surrounding environment.

The UltraLITE headset and each UltraPAK beltpack includes a rechargeable lithium battery. The battery is lightweight and only about the size of a book of matches. It charges in approximately 3 hours and operates the headset for 6 hours. The removable battery can be changed out in seconds and charged externally in the included multi-port charger.

Each UltraLITE wireless system includes a multi-port charger that can charge the headset and UltraPAK batteries in individual bays. When each battery reaches full charge, the corresponding LED turns from red to green, indicating that the battery is ready to go. This feature allows users to have extra batteries on hand in the charger whenever necessary.

Constructed of waterproof nylon, this headset case includes internal compartments, so the headsets stay organized. There is also a pocket with a hook-and-loop enclosure for the charger and any spare batteries. The molded hard plastic handle makes transport easy and convenient for location work.

Q: 5. Does this wireless intercom work in Brazil? What is the better option for me in this case, the USA set or Europe.

A: This system works in the 1920 to 1930 MHz range so if there are restrictions on using frequencies in that range in Brazil then these headsets will not be useable there.

Q: 6. the extrenal hub gives you more covered distance and better signal? im afraid of having interference on concerts with 2000 cellphones around...

A: The Eartec UL4S UltraLite system operates in the 1920 to 1930 MHz range. 900MHz, 1800MHz and 1900MHz frequencies are not used in the US with the exception of 1 band using 1900MHz. Most cell phones in the US operate in the 800MHZ frequency range. So the risk of any problems with cell phones is pretty much slim to none. Not to mention the protocols are different between cell phones and professional duplex intercom and IFB systems.

Q: 7. What region should I buy if I’m Mexico?

A: The USA version of the Eartec system will work in Mexico.

Q: 8. Can I add two headsets to my set?

A: Yes you can have one more headset without any additional hardware needed. If you need more then 5 headsets add the hub in the link bellow and that will allow you to use up to 8 headsets at once. If in the future you need more then 8 simply add another hub by connecting the two it will give you room to add 8 more headsets. https://www.bhphotovideo.com/c/product/1269407-REG/eartec_hub_mini_duplex_transceiver_base.html

Q: 9. If I work in a place where there are other equal teams, is there a problem? Each batch has different ip address number ?

A: These products do not have IP addresses. They work via RF signals. You may work with 3 separate systems simultaneously.

Q: 10. if I use 4 entire sets of this unit in a common space for 4 different user groups. will they work flawless without any crosstalk or interference.? also can I connect 2 or more Hubs together to get a larger common user group?

A: No, it is not possible to use four separate Eartec systems simultaneously in the same general open space because they would interfere with each other. However, the signal is not able to travel through walls or floors, so if the systems are placed far enough away from each other with walls or floors between each system, they could be used at the same time. But in one open space multiple systems cannot be used at the same time. It is possible to link two Eartec Hubs together to create a larger single wireless intercom system that will accommodate up to 16 users.
