AudioControl SA-3052 RTA with SA-3055 Upgrade

This is a legendary AudioControl real time spectrum analyzer used by professionals for audio signal analysis and car stereo competitions. The SA-3052 is a later incarnation of the SA-3050A. This unit has been upgraded to SA-3055 specs. It has automatic scoring functions, rechargeable battery pack, and printer output. This unit also has the Hi-SPL option installed but DOES NOT include the necessary SPL-180 microphone. It does include the standard CM-10 measurement microphone, 50' XLR cable, 20" RCA cable, 10' RCA to 1/4" cable, RCA to 1/4" adapter, power cord, manual and padded carry case. The manual is a reprint, not the original. There are more scoring features in this unit than are shown in the manual. I installed new batteries too so it will run for hours unplugged.

As you can see in the pics, I plugged the pink-noise generator into the 1/4" input to demonstrate the RTA and scoring, as well as show that the pink-noise generator works. The printouts are from this setup using the printer port. This device is fully functional and is in very good condition.
