Intraplex® STL HD
T1 STL System
Whether you’re looking for simple one­
way audio transport or multichannel FM
plus HD Radio™, control data, or off­
premises extension telephones, there’s
an Intraplex® STL HD package that’s
right for you.
STL HD is a modular family of products designed to let you
customize your T1 STL with exactly the features and circuits
you require. The system transports crystal­clear digital audio
over any distance or terrain, and can be used on all types of
