DOD RTA 4315 Real Time Analyzer

DOD RTA 4315 Real Time Analyzer -

A real-time audio analyzer (RTA) is an audio measurement tool that graphically shows two kinds of information:

1. The frequency response of an audio system or device, and 2. The frequency response of the listening environment. This kind of information is very useful for equalizing a P.A. system, finding feedback hot spots, or nodes, in reinforcement situations, and flattening the frequency response of other audio equipment. RTAs that show both the entire audible frequency spectrum (20 Hz to 20 kHz) and its entire dynamic range (loudness from 0 dB to 120 dB) are called spectrum analyzers. RTAs that show portions of the dynamic range are called window rta's.


The DOD Electronics RTA Series II is a window-type RTA. It covers the audible frequency spectrum (20 Hz to 20 kHz), and has a five LED level meter for each of the 31 audio frequency bands that it covers. This RTA Series II does not include a calibrated audio measurement microphone.

The sensitivity of the RTA can be modified using the input level control, and the window of the RTA may be widened or narrowed using the Resolution switch. This switch allows you to choose the LED display range in dB per LED. You can choose either a 1 dB per LED step (for a 4 dB wide window) or a 3 dB per LED step (for a 12 dB wide window).
