If you are using an AMX system to control your
DTR
20
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 just like native AMX equipment. The PT3 is
the fastest and most productive way to control
LecNet devices with an AMX system.
