PROBLEM CHART
Fan does not work, LEDs do not light up
Change fuse on rearpanel
Fan works, one of the Power LEDs does not light up
Change fuse of the individual channel (Type: T 6,3
A/250)
Protect LED lights up permanently
-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
Protect LED lights up, channel cuts off
-frequency exceeds 40 KHz
-frequency under 20Hz
Solution: connect mixer, equalizers, low-Cuts or high-
Cuts
Thermal LED no longer lights up
-device is overheated due to contamination. Clean
ventilation grille.
