The DM-RTA Pro Kit includes everything you need for a complete mobile audio measurement solution. Nestled snuggly in the fetching blue hard case, you will find an AC power supply, all of the required interconnects, and custom test leads for line-level and speaker-level measurements.The RTA (real-time analyzer) takes electrical and acoustical measurements. This will let you know how much equalization is needed to smooth out the frequency response of a vehicle. The sound pressure level (SPL) is used to show how loud the audio system can perform. This is something every customer would love to know and a way to test the before and after performance of a system. Testing speaker polarity is very important. All the tuning and setup means nothing if all the speakers aren't in phase. The oscilloscope measurement will give you a graphical representation of audio or electrical signals so that you can determine if these signals are distorted (clipped) or clean and their amplitude. This is extremely valuable when setting input and output gains on audio products.
