Audio signal generator
Audio, WAV NTi Audio

The MR-PRO is the professional analog audio generator providing a wide range of test signal, like sine, pink noise, white noise and many more. Proprietary user wave forms may be loaded via USB into the internal flash memory. Innovative technologies include continuous monitoring of the signal balance, the phantom power and the impedance of the connected load. The integrated cable analyzer simplifies trouble shooting tasks.

Generator Functions
- Sine Waveforms, freely selectable frequencies, up to +18 dBu
- Sweep Signals, any frequency interval up to 1/12 octave
- White Noise, Pink Noise
- Polarity Test Signal
- Delay Test Signal
- Wave Files (*.wav)

Measurement Functions in Generator Mode
- Balance
- Load Impedance
- Phantom Power Voltage providing a detailed view of the connected load for rapid fault finding.

Cable Test
The built-in cable tester measures any cable connected between the XLR output and the built-in XLR input. It detects all common XLR wiring faults with a precise description to the user, such as “2-3 Crossed” or “Pin 2 open”. Additionally an optional Cable Test Plug may be used for single ended installations.

Impedance and Power Test
The impedance test supports the verifications of distributed 70/100V loudspeaker installations and shows detailed information of the connected load.
- Impedance and Phase
- Apparent Power and Phase
