Building from a legacy of trusted professional audio measurement products, the DM-RTA™ brings the vital tools you rely on to one indispensable interface. Populated with every connector we could think of, and coupled with the new DM-RTA app, AudioControl’s DM-RTA helps you take your car audio, marine audio or home theater installations to new levels of perfection and control.

    The DM-RTA isn’t just an RTA. Accessible from the DM-RTA app are five modules, including Voltage Meter, RTA (1/3, 1/6, and 1/12 octave), SPL Meter, Polarity Checker and a fully functional Oscilloscope. Test and measure nearly every signal imaginable from acoustical, to line level, and speaker level. Balanced and unbalanced line level inputs allow the DM-RTA to be inserted into your signal chain to verify optimal signal from source to speakers. This is the last test tool you’ll ever need.

    AudioControl offers a wide range of professional measurement and instrumentation microphones which will make a perfect addition to your DM-RTA tool kit for making accurate acoustical measurements. For an entry-level measurement microphone, choose the CM-10, a long time standard issue microphone for AudioControl’s legendary SA-3052 analyzers. If you’re looking for a slightly better frequency response, look no further than the CM-20. The high-precision Josephson C550H rounds off the top of the list for truly accurate readings and impeccable frequency response.
