ATI HPSS: Difference between revisions
The American signal corporation (ASC) E-class is a separate product produced by a different company that the ATI HPSS-16 and HPSS-32, both sirens use the same DK TEC TU-300 speakers, which is why they look similar and how one could be mistaken for the other. However the control equipment, tones and mounts for the speakers are completely different. A good addition may be to either explain or visually show a different between these two very different models. |
