SBS,
for the first 4K OBVan in Korea, has selected LaON LT750 system, the newest and
high range wireless intercom system. The system offers wired-like audio clarity
with up to 7.2KHz audio frequency and supports 10 RBS repeater connection, and
the Belt Pack can be in master mode. It has been 3+ years since SBS became LaON
LT550 system users. There are many who have not yet experienced LaON 5GHz
intercom but no one who has used it just once.
