OFFSET ERROR DC VOLTAGE AT INPUT
With preamplifiers and other source devices, DC voltage may be present at the output.
To prevent this from damaging your loudspeakers, the 218 has active regulation that can
compensate for the DC voltage of source devices up to a certain level. If this DC voltage
becomes too high, the 218 switches off.
To reset the protection function:
1. Switch off the 218 completely by setting the power switch (6) on the back of the
device to OFF position.
2. Replace your source device and have it checked by your dealer.
3. After rewiring your components, switch on the 218 with the power switch (6)
and press the POWER button (1) on the front of the device.
Only switch on the device if you are sure that your preamplifier is set to a low volume.
ERROR INDICATION VIA BURLINK
The errors described can be read out separately for both channels via the BurLink
interface on the device:
Overvoltage at the
output (due to short
circuit in the wiring):
“END_OVERCURR:ERROR_R” or “END_OVERCURR:ERROR_L”
Overheating:
“END_TEMP:ERROR_R” or “END_TEMP:ERROR_L”
Offset error:
“END_OFFSET:ERROR_R” or “END_OFFSET:ERROR_L”
If the 218 does not return to normal operating mode after the measures described
above, there are other causes. Switch off the device and disconnect it from the
power supply by pulling out the power plug. Please contact your dealer.
