The Ahuja BTA-550 (KTI14006001A550) is an engineered 30W portable public address system designed for mobile sound reinforcement across industrial facilities, commercial operations, and field environments. Equipped with an 8-inch (20.32 cm) full-range dual-cone speaker, a 1.85-inch (4.7 cm) tweeter, and an integrated trolley chassis with rolling wheels and a retractable handle, this unit delivers versatile voice and audio reproduction where permanent PA installations are unavailable or impractical.
Industrial Safety Briefings and Plant Floor Announcements
Manufacturing plants, assembly floors, and logistics hubs require clear vocal clarity to overcome background acoustic noise. Delivering 30 Watts Max output with a signal-to-noise ratio exceeding 60dB, the Ahuja BTA-550 serves as an effective mobile speech station for daily shift kickoffs, Environmental Health and Safety (EHS) briefings, and emergency muster announcements.
- Microphone Priority Function: Automatically attenuates background music or auxiliary media playback on Mic-1 or the integrated wireless channel, ensuring critical voice instructions take precedence.
- Quartz-Controlled Wireless Channel: Handheld RF transmitter (15mW RF output, 50–15,000Hz response) operates at line-of-sight distances exceeding 20 meters, allowing safety managers to patrol shop floors while broadcasting directives.
- Active Tone Shaping: Dedicated Bass (±5dB at 100Hz) and Treble (±5dB at 10kHz) equalizers allow speech calibration to cut through high-reverberation industrial environments.
Outdoor Field Operations, Audits, and Off-Grid Site Inspections
Infrastructure audits, construction site surveys, utility maintenance, and remote open-yard operations frequently lack immediate access to AC mains power. The Ahuja BTA-550 incorporates a triple-source power architecture comprising 220V–240V AC (50/60Hz), an internal rechargeable 11.1V 2200mAh Li-ion battery, and external 12V DC car battery terminal inputs.
The internal battery management system includes an integrated auto cut-off protection circuit to safeguard Li-ion cells against deep discharge during long field shifts. Status LEDs indicate low battery, charging cycle, and output clipping, giving field engineers immediate operational feedback during remote public address tasks.
Technical Training, Workforce Seminars, and B2B Events
For corporate meeting rooms, training bays, temporary conference setups, and product demonstrations, the BTA-550 acts as a self-contained multi-source media hub. Its integrated digital player supports MP3 audio playback and recording via USB flash memory drives, MMC/TF flash cards, and Bluetooth wireless streaming, controlled directly through the front panel or the included IR remote control.
- Multi-Channel Connectivity: Houses two wired 6.35 mm microphone inputs (4mV/4.7kΩ) alongside one 6.35 mm Aux/Guitar input (100mV/47kΩ) for interfacing external audio players or acoustic instruments.
- System Expansion via Line Out: The 775mV line output jack enables routing to external mixing consoles, audio recording hardware, or secondary slave amplifiers for multi-zone industrial coverage.
- Digital Echo Effect: Built-in digital echo processing provides localized acoustic enhancement for presentations and specialized vocal applications.
