-inputs receive single-sided power; switch inputs off.
-impedance of speakers too low
-short-circuit in speaker connection or in speakers
-technical default of amplifier
-frequency exceeds 40 KHz
-frequency under 20Hz
Solution: connect mixer, equalizers, low-Cuts or high-
Cuts
-device is overheated due to contamination. Clean
ventilation grille.
