The amplifier supports both 70V and 100V installations without the need for a separate transformer. It has a universal power supply, accepting AC voltages from 100 to 240 VAC, 50/60 Hz. The NCSA240Z-U-US adheres to HARMAN's GreenEdge™ environmental initiative, promoting energy efficiency and sustainability. It features an auto-standby mode that conserves energy when no signal is detected. The amplifier also supports remote volume control using the JBL CSR-V module and standard Ethernet cable via RJ45 connectors. It is housed in a fanless, space-saving 1U half-rack design. Front-panel channel volume controls and LED indicators for clip, signal, and power are included for easy operation.
