Key Measurement Modes

Feedback Ring-Out Assistance

Identifies exact problematic feedback frequencies during monitor ring-outs and room tuning with peak hold markers and numerical Hz readout.

Pink Noise & Sine Sweep Generator

Generates reference Pink Noise directly through the device output or USB interface to check PA system flat frequency response.

Decay & RT60 Estimation

Measures reverberation decay times across individual octave bands to assess hall acoustic characteristics before the gig.

Measurement Mic Calibration

Supports custom mic calibration curves (.cal files) for external measurement microphones for studio-grade accuracy.
