Eton RTA 3.5 DSP Measurement Microphone

Microphone for real-time frequency response measurement and processing with DSP amplifiers STEALTH7.1DSP, MINI150.4DSP.

The ETON RTA3.5 is a newly developed, high-quality measurement microphone for measuring vehicle interior acoustics. The RTA function (Real Time Analyzer) is required to be integrated into the ETON DSP amplifiers. It enables fine-detail frequency response measurements in the vehicle interior and thus allows the user to optimally adjust the speakers and subwoofers installed in the vehicle to the acoustic conditions. The high-quality 160 mm aluminum SQ rod measurement microphone has a 5 m long, detachable, multi-shielded RCA jack cable specially designed for ETON amplifiers.

The RTA3.5 is designed specifically for modern Class-D amplifiers and can measure frequencies ranging from 20 Hz to 20 kHz. Its sensitivity is -35 ñ4 dB with a reference of 0 dB = 1V/pa at 1 kHz. The signal-to-noise ratio is greater than 62 dB, and the impedance is less than 2.2 KOhm. The operating voltage is 2 V with a maximum current consumption of 0.5 mA. The undervoltage operation of approximately -3 dB at 1.5 V ensures optimal measurement. This Real Time Analyzer and RTA3.5 measuring microphone allow for accurate time-of-flight corrections, actual-value control, precise adjustment of active filters (for the adjustment of crossover frequencies, shelf filters, and phase positions), and precise setting of EQ bands in the frequency spectrum. All of these features give you full control over your sound, and the device is Engineered in Germany.
