What a nice piece of equipment. It is an EQ/RTA and more. I am primarily using as an RTA but will eventually give it a whirl as an EQ. It makes crossover changes a snap to measure, You can verify slopes level and store and then compare to a new measurement. Very handy. Got the whole deal with a measurement microphone for $250! Not bad. If you are looking for a good measurement tool its worth a look.
