AMX Programming Notes
If you are using an AMX system to control your LecNet
equipment, you'll want to purchase the Lectrosonics
PT3 Protocol Translator. The PT3 connects between
the AMX bus and any LecNet equipment. With the PT3,
the LecNet equipment looks ust like native AMX
equipment. The PT3 is the fastest and most productive
way to control LecNet devices with an AMX system.
