Answer:
The AU-50XT is compatible with standard PA reflex horns and trumpets equipped with a 1-3/8” - 18TPI (Throat Couple No. 1) screw thread coupling.
The Ahuja AU-50XT uses the standard 1-3/8” - 18TPI throat coupling (Throat Couple No. 1). It threads directly onto industrial public address reflex horns, bell housings, and directional projector trumpets that utilize this mechanical interface.
On the electrical side, the unit connects directly to 100V constant-voltage output lines driven by commercial or industrial PA power amplifiers, booster amplifiers, and mixer amplifiers.
