System highlights

Operates in license-free 5GHz frequency
where there are less traffics and interferences with approximately 15 RF channels worldwide.
Super-scalable IP based repeater solution, RS(Remote Station)
can easily support for expanding the coverage and multiple studios or multi-floor spaces can be consolidated to one communication range. Up to five(5) RBS25 connections will support you to cover wider area with efficient system volume and the lowest cost. Prompt automatic or manual hands off is available between coverage.
Industry top level best-in-class audio performance with low latency
23ms low latency level and non-compressed audio transmission technology guarantee a high quality audio performance.
Five(5) communication group channel
Single or multiple communication group channels can be assigned to the Base Station, Belt Pack, 4-Wire and AUX devices each and those group channels can be used in single, multiple or all together at the same time. With this flexible grouping capability, one (1) Base Station covers IFB communication as well as IC and ISO communications without an additional IFB system which is ‘more with less’ cost efficient solution.
Eleven(11) full-duplex listen & talk communication channel (1 BS + 10 BPs)
Eleven (11) full-duplex audio channels are offered with one (1) Base Station. By making the full use of this with multiple group channels, a number of independent teams are practically able to have IFB and wireless communications in one (1) system respectively.
One hundred and twenty eight(128) Belt Pack connection
One hundred and twenty eight (128) Belt Packs can be registered into a Base Station.
4-Wire and Auxiliary I/O interfaces
4-Wire and Auxiliary Input/Output ports are provided to secure seamless connections with various traditional wired intercom systems, external audio devices and etc.
Compact design
Comfortable headset and compact Belt Pack with internal antenna support high wearability with mobility even at the tough broadcasting or live event sites.
Various options on battery
Either LaON provided rechargeable battery or AA type Alkaline battery with LaON provided designated battery sled can be used for supplying power to the Belt Pack. Also, non-LaON provided rechargeable battery can be used with the battery sled.
Monitoring functions
LT550 system provides various monitoring functions for Base Station, Remote Station and Belt Pack such as link status, RSSI(Received Signal Strength Indication), battery status and microphone gain level and etc.
Monitoring of audio break-up
When a Belt Pack is out of coverage, the Belt Pack user is easily able to monitor the audio break-up with his/her side tone.
Industry top level security with AES 256bit level 3 encryption
AES 256bit Level 3, the top level encryption technology is applied to secure confidential communications.
Efficient 7port charger
There are five (5) bays for charging the Belt Pack batteries which are equipped in the Belt Packs and two (2) bays for charging the Belt Pack batteries which are separated from the Belt Packs. Two (2) of them are for dual use for charging Remote Station or Mobile Station’s batteries.
