Rational RTA-420

RATIONAL ACOUSTICS RTA-420

The RTA-420 is a great little budget-friendly measurement mic with an impressively flat response curve for its price. The RTA-420 features heavy-gauge steel construction and measurement performance to rival high-end microphones costing many times more. Makes a great starter mic, spare or "B" rig mic and goes places you would be nervous to take your high-end, lab quality mic.  The RTA-420 makes multi-microphone measurements affordable for the rest of us.

The Rational RTA-420 comes with a mic clip and a spiffy bright yellow windscreen, which is great for spotting your mic in dark venues. And, it includes a custom-designed soft-sided carrying case that accommodates and organizes 2 microphones plus their accessories.
