Product Features
・Slim Profile
Designed to complement compact machinery on production lines, this is our slimmest model yet—measuring only 19.9 mm in depth.
Despite its thin build, it achieves up to 87 dB at a 1-meter distance.
Front-access volume control and a low power consumption of just 3.5W (max) help reduce strain on the power supply.
・Front-Facing Installation
Maintenance is streamlined thanks to tool-less front panel access. The front cover can be easily detached for mounting and volume adjustments, helping to reduce installation time and labour costs.
・Flexible Message Updates
An SD card slot comes standard, allowing you to overwrite MP3 files directly.
You can update files using dedicated application software, or simply by renaming/replacing MP3 files on the SD card—no software needed.
・Extended Audio Playback
The BSV-L model supports long-form messages up to 520 seconds at 64 kbps bitrate.
This makes it ideal for detailed instructions, multilingual guidance, or extended alert sequences.
- Long Play Model: Approx. 520 sec (64 kbps)
- Standard Model: Approx. 63 sec (64 kbps)
