NTi Audio Test Equipment

Selecting the appropriate test equipment can sometimes be problematic especially where there is a function overlap between different pieces of test equipment. In order to aid the selection of the correct kit for the job here is a brief overview of the NTi test equipment range. RK Sound Engineering will always be happy to help with product selection and remember we use this equipment ourselves so we can share the benefits of our experience with you.
