AudioControl DM-RTA Pro Kit Review: Specifications, Uses and Comparisons
Quick summary: the buying decision
The DM-RTA Pro Kit is a complete mobile audio measurement kit: the DM-RTA real-time analyser with a CM-30 measurement microphone, power supply, interconnects and spring-loaded test leads for line-level and speaker-level measurements, all in a blue hard case with laser-cut foam. It is the simplest way to buy everything needed to measure and tune a system in one order.
AudioControl DM-RTA Pro Kit: what it is
The AudioControl DM-RTA Pro Kit is a complete mobile audio measurement solution: the DM-RTA real-time analyser with a CM-30 measurement microphone, power supply, interconnects and custom test leads for line-level and speaker-level measurements, all in a blue hard case with laser-cut foam.
The Pro Kit packages the same DM-RTA analyser sold on its own; if you already own the analyser, the DM-RTA Base Kit adds the case and accessories without a second analyser.
Key features
Real-time analyser (RTA) for electrical and acoustic measurements, showing how much equalisation a vehicle needs
SPL measurement to show how loud a system plays, before and after an upgrade
Speaker polarity testing to make sure every speaker is in phase
Oscilloscope for checking signals for clipping and amplitude when setting gains
Signal generator output up to 5 V RMS; balanced, unbalanced, coaxial, optical and USB outputs; about 5 hours of battery life
Specifications explained
Inputs: 1 x balanced (3.24 kohm), 1 x unbalanced (3.24 kohm), 1 x microphone (10 kohm), 1 x speaker-level (16.24 kohm). The low-level inputs accept up to 8 V RMS and the speaker-level input up to 40 V RMS.
Outputs: 1 x balanced and 1 x unbalanced (51 ohm), 1 x coaxial digital (75 ohm), 1 x optical (Toslink), 1 x USB. The signal generator outputs up to 5 V RMS / 7 V peak, battery life is about 5 hours, and the analyser measures 8 x 4.8 x 2.4 in and weighs 1.2 kg (2.6 lb).

What you can measure
RTA: how much equalisation the car needs, measured acoustically with a microphone or electrically at line or speaker level
SPL meter: how loud the system plays, before and after an upgrade
Polarity checker: confirms every speaker is wired in phase
Oscilloscope: checks signals for clipping and amplitude when setting amplifier gains
Voltage meter and signal generator: test tones up to 5 V RMS for gain setting and fault-finding
Using it in a tuning session
Insert the analyser into the signal chain to check the signal from source to speakers: confirm the head unit or processor output is clean, set amplifier gains against the oscilloscope rather than by ear, check polarity, then measure the in-car response with a microphone at the listening position. The microphone input has 48 V phantom power, variable gain and presets for AudioControl's CM-20, CM-10 and C550H microphones.
Connection is by USB to a Mac or PC, or by Bluetooth to a phone or tablet with the optional AC-BT24 plugged into the Option Port.
