Microsound grew up with most of us. There’s hardly a School Teacher, a Secretary or Principal that hasn’t at some time or other addressed his students through a Microsound School Intercom System. Created in 1986 and has been producing good quality Products.

Known over the years for supplying reliable and locally manufactured intercom. Nurse-call, public address and access control products, Microsound now gears itself to face the new Millennium.
