System highlights

LaON’s patent-technology base digital wireless intercom system offers the best audio quality with an excellent clarity by using
worldwide license free 5GHz UNII band and frequency interference avoidance technologies. It guarantees the system stability
even in the large congested site environments where various A/V and wireless equipments are co-located while offering the
super-scalability with the exceptional IP based repeater, RBS75. LT750 is high range professional system that offers advanced
and unique features for using at large venues, stadiums, stations, OB trucks and etc.

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 ten(10) RBS75 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 up to 7.2KHz audio frequency guarantee a high quality audio
performance. LT750 system is perfectly tuned professional wireless intercom system that fits to use in various loud and congested site environments.
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.
Belt Pack in master mode: A Belt Pack can play a role as a master where there is no Base Station or the Base Station is located far from the actual Belt Pack operation area.
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: LT750 system provides various monitoring functions for Base Station, Remote Station and Belt Pack such as the frequency being occupied, 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.
