True Level Output Stage
The compensated output stage of MR-PRO precisely stabilizes to the specified output level over a wide range of varying loads. Possible deviations at reaching the output current limit are clearly indicated.
|
MR-PRO Wave Forms
|
Sine Output
MR-PRO generates extremely pure sinusoidal waveforms with
freely selectable frequencies from 10 Hz to 20 kHz
level range from -80 to +18 dBu
|
|
|
Sweep
The start frequency, stop frequency and a step resolution as fine as 1/12th of an octave can be adjusted. Analyzers like the Minilyzer automatically trigger to this signal and record the frequency response of a device under test.
|
|
|
Chirp
The chirp signal is a sine-wave with defined start- & stop frequency and continious frequency increase over time. It is used in the recording of frequency responses, the measurement of impulse responses and the acoustic assessment of rooms.
|
|
|
Delay Test Signal
This is the designated reference signal to measure the acoustics progagation delay time from speaker to speaker in e.g. churches or auditoriums. Testing is carried out in combination with the Acoustilyzer AL1.
|
|
|
Pink & White Noise
Pink or White Noise is synthesized with high spectral density, normal amplitude distribution and with infinite cycle duration. An automated on-off cyclic mode for convenient RT60 measurements with the Acoustilyzer AL1 is included.
|
|
|
Polarity
The saw-tooth waveform of the polaritytest signal is an ideal stimulus with only moderate stress to speakers. Minilyzer ML1 and Acoustilyzer AL1 take advantage of this and correctly analyzes the polarity of the incoming signal.
|
|
|
Wave File
A number of user test signals may be stored as uncompressed WAV-files in the MR2-PRO memory. The selected file is seamlessly looped. Data exchange is simplified via the USB port.

Screenshot Examples
|
|
The sine wave is the most common waveform in the audio world for measurements of frequency response, distortion and for setting up levels.
|
|
|
In the sweep mode the output sine signal is sequentially stepped trough all available frequencies. Analyzers like the Minilyzer ML1 can follow this signal and automatically record a frequency response graph of a device under test.
|
|
|
The polarity test signal is a saw tooth signal with 20Hz, which is suited for speaker and system polarity checks. The Minilyzer ML1 knows this waveform and therefore can analyze the incoming signal for correct polarity.
|
|
|
For room acoustic measurements and quick frequency response checks Pink Noise is a very important signal. Pink Noise has an equal power per octave and is used together with 1/3rd octave or RTA analysers.
|
|
|
White noise has an equal power per Hertz between 20Hz and 20kHz. It is most often used for system analysis with a FFT spectrum analyser.
|
|
|
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.
|
|
|
On the set-up page you may configure the auto power off time, the preferred level unit (dBu, dBV, Volt) and the speed of the sweep signal.
