NBS-2301P26 is a 2U rack-mounted multi-zone IP mixer amplifier designed for supermarkets, schools, office buildings, and public facilities. Featuring a built-in 260W Class-D amplifier, it supports both 100V constant-voltage and 8?16O speakers, enabling flexible system deployment.

With four independently controlled zones, built-in microphone and speaker for intercom, and SD card support for offline scheduled broadcasting, the amplifier ensures continuous operation even if the server fails. It also supports real-time paging via SIP/VOIP devices and integrates with third-party systems such as fire alarms through relay I/O ports.
