The Ahuja SSB-120DP 120W medium-wattage public address mixer amplifier is engineered for continuous B2B and institutional sound reinforcement. With support for 5 dynamic microphone inputs, 2 auxiliary line inputs, low-impedance (4Ω, 8Ω, 16Ω) and constant-voltage (70V, 100V) speaker outputs, and dual AC/DC power options, it integrates reliably into a broad range of facility audio architectures.
Industrial Plants, Warehouses, and Workshop Paging
In manufacturing environments, industrial fabrication shops, and logistics hubs, audible voice clarity over ambient floor noise is critical for operations and facility safety. The SSB-120DP provides a rated 120W RMS power output (up to 160W RMS maximum) across a 50 Hz to 15,000 Hz frequency range, driving high-efficiency 70V or 100V line-matching transformer speaker and horn networks over extended cable runs without line loss.
- Emergency Failover: Supports automatic changeover to external 12V DC battery power (5.5A consumption; batteries are not included) during 220–240V AC mains interruptions to maintain uninterrupted public address capability.
- Visual Monitoring: Integrated 5-LED visual output array allows plant engineers to monitor audio drive levels and prevent clipping distortion.
Educational Campuses, Auditoriums, and Assembly Halls
Schools, colleges, and training auditoriums require balanced voice reproduction across wide seating areas alongside automated audio playback. The mixer section accommodates up to 5 microphone inputs (0.65mV / 4.7kΩ) for podiums, panel desks, and stage presenters, alongside 2 auxiliary inputs (100mV / 470kΩ) for multimedia players.
- Integrated Media Playback: Front-panel digital player accepts USB flash drives and SD/MMC media for pre-recorded school bells, announcements, and event playback, operable via front-panel controls or an IR remote control (remote cells are required; they are not included).
- Archive Recording: Built-in preamplifier output (200mV / 600Ω) feeds external recording equipment or secondary audio circuits to archive assemblies, lectures, and proceedings.
Places of Worship and Multipurpose Community Centers
Houses of worship and multipurpose halls demand high speech intelligibility, multiple simultaneous open microphones, and tone adjustment to match architectural acoustics. The SSB-120DP features dedicated cut-and-boost bass and treble tone controls (±8dB/±10dB at 100Hz and 10kHz) to eliminate room boominess and enhance vocal articulation.
- Low-Impedance & Multi-Zone Support: Direct 4Ω, 8Ω, and 16Ω terminal connections accommodate low-impedance distributed wall speaker clusters for close-proximity sound coverage.
- System Expansion: Built-in 1V / 1kΩ line output interfaces directly with high-power booster amplifiers to scale audio coverage across overflow halls, courtyards, and perimeter zones.
Commercial Complexes, Corporate Offices, and Retail Facilities
For corporate buildings, commercial showrooms, and multi-tenant complexes, the amplifier delivers background music (BGM) and zone paging through its dual auxiliary inputs and mixed mic channels. The ≤ 2 dB output regulation ensures uniform sound pressure levels across all connected 100V ceiling speakers as individual speaker taps are activated or adjusted.
