Product description Key benefits Update voice files quickly and without software: copy voice files directly via USB — no driver or software installation required. Faster updates reduce downtime and simplify content changes. Ready for integration with external control systems: the dedicated BUSY output indicator provides a clear hardware signal to other devices so you can coordinate playback and system state reliably. High-quality audio output: 24-bit output with dynamic support up to 90 dB and a ratio of 85 dB delivers clear, detailed voice playback for announcements and alerts. Simple host-PC support: specially designed to work with an upper computer (host PC). Commands and instructions are executed automatically for easy remote control and automation. What it does and how it solves problems Eliminates complicated update processes: the USB copy method removes the need for installers or proprietary software, saving time for field technicians and reducing points of failure. Improves system interoperability: the BUSY output gives an unequivocal hardware signal to PLCs, controllers, or audio switches, preventing overlapping messages and improving sequence control. Delivers intelligible voice output in noisy environments thanks to 24-bit audio and a 90 dB dynamic capability, improving message clarity and user comprehension. Simplifies automation: upper computer support allows playback to be triggered or scheduled from your existing control system with automatic instruction execution. Compatibility and performance USB-based voice file updates; compatible with Windows XP series, Windows 7, Windows 8, and Windows 10 systems. Audio performance: 24-bit output; dynamic support 90 dB; ratio 85 dB. Hardware integration: dedicated BUSY output indicator for external device coordination. Control integration: supports upper computer control; instructions performed automatically for streamlined operation. Practical use scenarios Public information kiosks and transit systems: quickly update announcements via USB and use the BUSY output to prevent message overlap with other systems. Factory automation and safety alarms: integrate with PLCs or control software (upper computer) to trigger voice alerts automatically; BUSY output ensures clear sequencing during emergency procedures. Retail or hospitality environments: maintain clear, high-quality pre-recorded messages and schedule content from a host PC without installing extra software.
