    If you can possibly, take the OS4 back and get an OS3. Your life will be 100x easier hooking it up, im not a huge fan of OS4's they are universal for alot of applications compared to the OS3 which is specific to your application

    What kind of system are you running? Double check your connections, sounds likes something isn't hooked up right.
