The Minirator MR2 and MR‑PRO are analog audio signal generators that produce sine waves, sweeps, pink/white noise, and user‑defined waveforms for calibration, maintenance and repair of professional audio equipment. The instrument offers high frequency resolution, low distortion, and optional cable‑testing capabilities.
This manual describes how to operate the device, configure presets, use the USB interface for firmware updates and waveform loading, and explains the technical specifications such as output level, impedance, THD+N, battery life and dimensions. Accessories and optional parts are also listed.
| Frequency resolution | 0.01 Hz |
|---|---|
| THD+N (MR2) | < -90 dB (0.003 %) |
| THD+N (MR‑PRO) | < -96 dB (0.002 %) |
| Output impedance (MR‑PRO) | 12.5 Ω balanced |
| Preset configurations storage | Up to 10 complete configurations |
| Battery life (MR‑PRO) | 10 h typical |
Up to 10 complete instrument configurations can be stored in the internal flash memory.
Yes, user waveforms in uncompressed *.WAV files can be stored and played back via the USB interface.
The MR‑PRO achieves THD+N better than –96 dB (0.002 %).
