Lab.gruppen FP 2200 User Manual

NM=j^fkqbk^k`b=
Under normal use the amplifier should provide years of trouble-free service. The only user maintenance
required by the user is to vacuum the front grille periodically.
In some extreme cases it may be necessary for authorized service personnel to clean the inside of the
amplifier. These conditions usually occur after prolonged use, e.g. in environments using "cracked oil"
smoke machines.
If you are using your amplifier for heavy duty use, i.e. for concert touring or with “industrial” music, it
is recommended to have your amplifier serviced every 3 years, purely as a preventative measure.

These are typical things to check if you think your amplifier is faulty:
Fault: No output.
If the output bar-graph is illuminating, there is nothing wrong with the amplifier; the likely cause is an
unsecured Speakon speaker connector.
Check also if the VHF protection is activated. If it is, remove possible high frequency oscillations from
the relevant input.
Fault: The amplifier goes into thermal protection when running at low levels.
Check that nothing causes a short circuit at the amplifier's output, e.g. any component in the
loudspeaker (this can occur when the speaker coil gets hot).
Fault: The amplifier goes into protection with the power indicators off.
Check if the AC mains voltage is within the amplifier’s operating range, 130-265V at nominal 230V
(65-135V at nominal 115V). Over-/under-voltage protection may have occurred. If the amplifier was
incorrectly connected to a 3-phase distribution by mistake (415V), an internal non-resetable fuse or
resistor may have blown. In this case return the amplifier to your supplier for service.
Fault: The amplifier does not respond even after having checked the above items.
In the unlikely event of on a non-user-rectifiable fault return the amplifier to your supplier, or an
approved service centre.
