Answer:
The amplifier features dual-source power operation with an automatic instant transfer mechanism that shifts operation from AC mains (220–240V) to an external 12V DC battery (they are not included) without audio interruption.
The Ahuja SSB-45EM is equipped with dual AC and DC power connectivity to ensure uninterrupted public address coverage:
- Automatic Transfer: When connected simultaneously to AC mains (220–240V AC, 50/60Hz) and an external 12V DC battery (they are not included) via rear terminal screws, the amplifier instantly shifts to DC backup operation if the AC power supply fails.
- Continuous Public Address: This automatic switchover prevents communication dropouts during emergency announcements or industrial paging operations.
- DC Power Consumption: Consumes 2A current during 12V DC operation.
