This handy Audio Generator enables you to stimulate any analog device with a broad range of appropriate signals for performance checking, maintenance and repairs. Sine Output A pure sinusoidal waveform is required for almost every audio measurement. The wide level range from -76dBu up to +6dBu and selectable frequencies over the full audio band allow the MR1 to replace any signal source Sweep In the sweep mode the output signal is sequentially stepped through all available frequencies. Analyzers like the Minilyzer can automatically trigger to this signal and record the frequency response of a device under test. Polarity The saw-tooth waveform of the polaritytest signal is an ideal stimulus with only moderate stress to speakers. Minilyzer ML1 takes advantage of this and correctly analyzes the polarity of the incoming signal. Pink Noise Pink Noise is the most important test signal in conjunction with a RTA analyzer as it features equal power per octave, providing a flat response curve. The MR1 Pink Noise signal has a very low crest factor. White Noise White Noise is the most important test signal in conjunction with FFT Analyzers as it has an equal power per Hertz between 20Hz and 20kHz. It is therefore the ideal test signal for the Acoustilyzer AL1 Zoom FFT function. Square Wave The square wave has many harmonics and is sometimes used for aural system testing. The MR1 has a bandwidth of 20Hz to 20kHz, a perfect 50% duty cycle and is DC offset free.
