Not all fuse blocks are created equal, and choosing the right one can make a real difference in the way your system sounds.

Every system has different needs: some are compact and tidy, others have many outputs and significant loads. This is why ISP Audio has created three categories of fuse blocks , designed to adapt to every situation:

• SlimCore → small and compact, perfect for systems with up to 6 outputs
• TwinCore → versatile, manages power and mass in the same product
• PowerCore → large and powerful, up to 20 outputs for demanding systems

In the following paragraphs, you'll discover each category in detail, making it easy to understand which model is right for you.
