The new ONE-150 model<\/a> addresses a common challenge: meeting the standard without going beyond what the project actually needs in terms of power or functionality.[\/vc_column_text][vc_column_text css=”.vc_custom_1788027864080{margin-top: 30px !important;}”]<\/p>\n

A series that keeps growing towards smaller installations<\/h3>\n

The ONE series was built to make certified voice evacuation accessible in medium and small-scale projects. Mini ONE takes that approach one step further, fitting naturally into environments such as retail premises, sports centres, low-occupancy public buildings and franchise networks.<\/p>\n

It shares the same design principles as the rest of the series: compact format, flexible installation in Wall & Rack configuration (rack, desktop or wall mount) and straightforward integration in spaces with physical constraints<\/strong>.[\/vc_column_text][vc_column_text css=”.vc_custom_1788259042002{margin-top: 30px !important;}”]<\/p>\n

Typical use cases<\/h3>\n

\"Wall-mounted<\/a>In small-format retail<\/strong>, the ONE-150 enables the deployment of a standalone system per location without any need for interconnection between units. The absence of cascading reduces design complexity and makes it easier to standardise the project across multiple sites.<\/p>\n

In dual-purpose spaces<\/strong> such as cultural venues or multipurpose halls, the two-zone configuration allows evacuation announcements and background audio to be managed separately, without additional amplification equipment. This simplifies both the cabling layout and ongoing maintenance.<\/p>\n

In projects with space or technical infrastructure constraints<\/strong>, such as small public buildings, the Mini ONE architecture with integrated main\/backup amplification eliminates the need for auxiliary racks or external redundant systems, while maintaining EN 54-16 compliance within a single unit.[\/vc_column_text][vc_column_text css=”.vc_custom_1788259077553{margin-top: 30px !important;}”]<\/p>\n

Technical features focused on efficiency and compliance<\/h3>\n

The ONE-150 integrates two Class D amplification channels with a maximum output of 150 W per EN 60065, in a main\/backup configuration. This ensures system continuity in the event of a failure, meeting EN 54-16 requirements.<\/p>\n

It supports either an A\/B zone layout or two fully independent zones, with speaker line supervision and end-of-line supervision terminators.<\/p>\n
