3.5IMPORTANT NOTE: firmware v0.0.64 and above is required for proper operation. DM-RTA signal analyzer provides five of the most important tools that installers use to make systems sound perfect. The DM-RTA can also generate the test tones and signals used for analysis, like sine waves, clicks, and pink noise. This portable device features a built-in battery, which can keep its charge for about 3 to 5 hours, giving you plenty of time to take readings in a vehicle before needing a recharge. There's even 48-volt phantom power available for the microphones that need it to operate * RTA, or real-time analyzer, visualizes system response across the entire sound spectrum. You can measure the acoustic response using a microphone, or the electrical response using the line inputs. * Voltmeter displays a signal's voltage, so you can match a device's output to another's input sensitivity. * Polarity Checker makes sure all your drivers are moving in the same direction at the same time. * SPL Meter helps you level-match your speakers. * Oscilloscope displays signals as sine-type waves that show a sound's frequency, voltage level, and whether or not it's clipping five-in-one signal analyzing tool voltage meter (Vrms). * Real-time analyzer (RTA) 1/3, 1/6, or 1/12 octave resolution. The DM-RTA app works with mobile device using a Bluetooth connection.
