The Ahuja SSB-45EM is an industrial-grade 45-Watt medium-wattage public address mixer amplifier engineered for continuous voice distribution, background music playback, and safety paging across small-to-medium facilities. Featuring dual-power operation (220–240V AC and 12V DC battery support), three balanced/unbalanced microphone inputs, one auxiliary channel, and selectable direct low-impedance (4Ω, 8Ω, 16Ω) plus distributed 100V line outputs, the unit integrates smoothly into diverse institutional, commercial, and industrial sound architectures.
Educational Facility Paging & Assembly Sound Systems
In schools, colleges, and training institutes, the Ahuja SSB-45EM serves as a dependable central amplifier for morning assembly grounds, multipurpose lecture halls, and administrative public address networks. The 3 Mic inputs (0.65mV / 4.7kΩ) accommodate multiple dynamic microphones—such as the Ahuja ASM-580XLR, AUD-101, or AUD-77DX—for podium speakers and announcers, while the dedicated auxiliary input (100mV / 470kΩ) allows playback of bells, anthems, or audio lessons from media players and laptops. Output regulation of ≤ 2 dB ensures stable volume and vocal clarity across classrooms or courtyard speakers.
Factory Floor Announcements & Warehouse Operations
Manufacturing floors, dispatch bays, and logistics warehouses require high-intelligibility paging capable of cutting through background plant noise. The SSB-45EM delivers 64W Max (45W RMS at 10% THD) across a broad 100 Hz to 15,000 Hz frequency response. For multi-building sites or extended factory corridors, the 100V line output allows distributed speaker arrays equipped with line matching transformers to run over long cable distances without line-loss degradation.
During AC power outages on the plant floor, the unit provides instant automatic transfer to an external 12V DC battery (they are not included), drawing 2A DC to maintain uninterrupted emergency announcements and operational shift signaling.
Places of Worship & Community Hall Voice Reinforcement
Acoustic management in prayer halls, temples, mosques, and community centers benefits from the amplifier's built-in cut-type tone shaping controls (-10dB at 100Hz for Bass and -10dB at 10kHz for Treble). These tone filters eliminate low-end boominess and suppress high-frequency feedback in reverberant spaces. A 60 dB signal-to-noise ratio maintains clean, intelligible speech reproduction across seated congregations.
Commercial Retail Spaces & System Chaining Deployments
For retail showrooms, clinics, and hospitality venues requiring zoned coverage or audio logging, the SSB-45EM includes a dedicated preamplifier output rated at 200mV / 600Ω. This preamp feed connects directly to external booster amplifiers for high-wattage expansion across larger zones or feeds line-level signals into dedicated recording consoles for archival storage.
Application Configuration Matrix
