These rack ears make it convenient to mount your Audient EVO16 in any 1RU space. They are easily installed with a 3mm hex driver/key and Pozidrive screwdriver, and painted black to match the EVO16. Note: Audient recommends at least one rack unit of space above and below the EVO16 to prevent overheating. Additionally, while Phillips screwdrivers can technically be used in place of the Pozidrive, it is not recommended. Please consult us if you have any questions or concerns about mounting the Audient EVO16.
