Product Information
Full details
The Comelit 4888C is an 8-DIN module power supply mixer designed for SimpleBus systems, ideal for installers managing larger residential or commercial setups. Its key benefit is the ability to power and manage up to 100 devices across four outputs from a single unit, simplifying installation and maintenance. A potential caveat is its specific compatibility with SimpleBus 2 products from version IR013 onwards, requiring careful system verification.
