Unlike conventional portable megaphones that utilize analog Class-AB drivers, the Ahuja AM-30SS incorporates a high-efficiency Class-D amplifier circuit. This digital amplification stage significantly curtails thermal loss and electrical power drain, thereby extending operating run-times under heavy usage in remote marshalling environments.
To convert this electrical output into high sound pressure levels (SPL), the transducer assembly employs an enlarged voice coil paired with a high-flux magnetic structure. Operationally, the unit provides two deployment formats: it can be deployed as an integrated hand-held unit via its hand grip or slung over the operator's shoulder using the provided sling strap while speaking through the dedicated unidirectional microphone. Additional built-in signaling is provided via a three-level siren tone selector switch located on the chassis.
