Moseley Associates used the NAB Show to debut a dedicated digital composite STL box called Topanga.
According to the company, Topanga has a greater than 20 dB system gain advantage over analog composite systems which should guarantee improved signal to noise rations and stereo separation.
Besides the MPX feed, Topanga has an Ethernet interface for HD Radio data along with RS-232 channels for RDS. It can be operated through the front panel or remotely over the internet.
In addition, Topanga has Moseley’s new 5 W transmitter, which is also being added to the Starlink RF STL.
