This powered mixer/amplifier combines a mixer and an amplifier into a single unit, making it easier to transport and set up for various audio needs. It is built with Crown's DriveCore™ technology, which enhances efficiency and reliability by minimizing the component count and generating less heat. The NCSMA1120-U-US boasts a sleek and intuitive front panel interface featuring illuminated volume controls for each of the four input channels, a master volume control, and adjustable bass and treble controls, according to Creation Networks. It can handle 8-ohm and 4-ohm loads and is also compatible with 70V and 100V distributed audio systems without needing an additional transformer. It includes an auxiliary output to connect to an additional amplifier, however, the master volume and tone controls will have no effect on the output signal.
