JBL NCSM28-U-US 8-input 2-output audio mixer

8-input 2-output mixer for fixed installs

The JBL NCSM28-U-US is a fanless audio mixer built for permanent rack installations. It provides eight input channels and two output channels in a single rack unit. The silent design suits environments where mechanical noise must be absent. Installers gain a compact mixing solution for background music or paging systems.

Silent thermal design for rack cabinets

Passive cooling eliminates fan noise and moving-part wear in the 1U enclosure. Heat dissipates through the chassis during continuous operation. The fanless architecture reduces maintenance visits in locked equipment rooms. Power consumption remains low enough for standard rack power distribution.

Eight inputs and two outputs define capacity

The channel count sets the limit for source devices and zone feeds. Projects requiring more than eight sources or additional output zones need a different mixer. Buyers who need more inputs or outputs should verify the requirement before ordering. The fixed I/O configuration cannot be expanded later.
