Built to last

 

The S418HA rack-mountable design will work into your existing system easily, and its low-noise toroidal transformer provides superior output power and headroom. Plus, its cascading feature via parallel balanced ¼” outputs allow you to add additional S418HAs, making it easy for you to scale up your system as needed. Gold-plated inputs and outputs and a sturdy steel chassis guarantee optimal operation for years into the future.
