BLASI – PCB amplifier board TA-4 control unit
The BLASI PCB amplifier board for TA-4 control unit is a specialized audio power module integrated within revolving door control systems. This PCB drives high-fidelity speakers for voice announcements, safety instructions, and operational status messages synchronized with door movements. Featuring efficient Class D amplification, thermal protection, and direct TA-4 logic board integration, it delivers clear audio above ambient entrance noise. Compact design of this PCB amplifier board fits standard distribution panels while providing robust sound output essential for commercial safety communication and user guidance.
Product Details
The BLASI PCB amplifier board powers the audio announcement system within TA-4 controlled revolving doors, amplifying MP3 module signals to drive multiple entrance speakers with professional audio quality. Class D efficiency minimizes heat generation while delivering sustained high-volume output required for noisy commercial environments. Direct digital connection from MP3 module eliminates analog noise while embedded DSP maintains consistent voice clarity across frequency spectrum.
Precision volume control synchronizes announcement levels with operational states – normal volume for routine guidance, elevated levels for safety alerts, and maximum priority for emergency instructions. Thermal and short-circuit protection ensures continuous operation through power fluctuations common in commercial facilities. Field-replaceable design mounts securely within TA-4 distribution panels using standard connectors compatible with Service-IBS diagnostic access.
Essential for regulatory compliance requiring audible safety communication, the amplifier board maintains crystal-clear instructions in hotels, hospitals, offices, and public buildings where voice guidance prevents accidents and improves user experience during high-traffic periods.
