5 TROUBLESHOOTING

5. Troubleshooting

5.1 Problem: No reaction when switching the amplifier on

If nothing happens when switching the amplifier on (i.e. the display stays
totally dark, no message inside the display), please check following points:

Check mains cable and plug
Confirm that the AC outlet works by plugging in any other device

5.2 Problem: No sound

If no sound can be heard on the outputs please check following DSP set-
tings (through the DSP control application):

Input source selection
Input and output gain settings
Input and output limiter settings
If digital (AES) input signal is used, please check AES signal source

(samplig frequency, bit resolution and signal quality (long cables))

5.3 Problem: Error message: “Error – amp switched off”

This error message indicates an internal error which forced the main
power supply (SMPS) to be switched off. This can be caused by:

Detection of permanent DC on the outputs
Detection of amplifier stage malfunction (protect)
Detection of main SMPS error

You can try to power-cycle the amplifier to reset all amplifier stage detec-
tion circuits. This might help in case the DC or amplifier fault was caused
by an invalid input signal (e.g. an extremely high frequent or extremely
distorted input signal).
For this please switch off the amplifier for at least 4 minutes and switch
the amplifier on again. If the message still appears after this procedure the
fault is permanent and the amplifier requires servicing.
