Frequently asked questions
Which amp is better for a multi-zone installation?
The NCSA280Z with its dual 80W channels is designed to handle multiple zones or speaker pairs in one unit. The NCSA1120Z single channel is best when you only need to power one speaker or load.
Do both amplifiers support 70V and 100V distributed systems?
Yes, both units support 70V and 100V configurations via RJ45 connectors. This makes either suitable for commercial distributed audio installations.
What is the key power output difference?
The NCSA1120Z delivers 120W on one channel, while the NCSA280Z delivers 80W per channel across two channels (160W total). The 1120Z concentrates more power into a single load; the 280Z distributes power across two separate loads.
Which is easier to integrate with networked volume controls?
The NCSA280Z includes illuminated control knobs and specific RJ45 connectors designed for JBL CSR-V networked control systems, making it the better choice for installations requiring centralized or remote volume management.
