Choose 30, 60 or 90 seconds and repeat whenever the sound seems muffled. FREQUENCY STUDIO A tone generator from 20 Hz to 20 kHz with six waveforms and adjustable intensity. SPEAKER TEST Check left and right channels, stereo, bass, treble and balance with dedicated test tones. DECIBEL METER Measure sound levels in dB with live minimum, average and maximum readings.
