An RTA Analyzer Overview 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” RTAs. About the DOD RTA Analyzer 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. The RTA Series II is calibrated with an special audio measurement microphone. ONLY A RTA MICROPHONE SHOULD BE PLUGGED INTO THE JACK ON THE FRONT OF THE PANEL OF THE RTA. Other microphones may be damaged or give inaccurate readings. 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). The DOD RTA Series II also has its own internal pink noise generator and level control. Pink noise is defined as an audio signal that contains all frequencies at equal energy levels. For this reason, pink noise sounds a lot like static. Pink noise is useful when setting up P.A. systems and audio systems when you need to see the frequency response of the system. On the rear of the unit is an auxiliary microphone jack for use with other measurement microphones, and an output jack for the pink noise generator. When the pink noise is off, this jack acts as an audio output so that the signal may be looped through the RTA and monitored during a performance. There is also an input jack that allows you to directly analyze equipment in a system. Payments: Payments must be received in full within 3 days of close of auction/sale.
