Super Convenient Tool

What better way to use the AudioControl RTA!! Yes we can use a computer and have it hardwired but most of us would like to reduce extra things to hook up and do it from outside the vehicle.

Doesn’t work via Bluetooth anymore

App used to work but is now garbage, makes since with the company changing hands. Get a new RTA and get away from Audio control and PAC. There are more reliable options for professional use.
