THORENS TEM 3200, User Manual

Trouble shooting
13
Problem: Abrupt shutdown of the amplifier while blue
THORENS writing is flashing.
Cause: The unit was highly overloaded, having the integrated over-
load protection turn off the amplifier to prevent damage.
Solution: Switch off the amplifier using the power button and find
and remove the reason for the overload.
Possible sources are too high input signals (e.g. turning up to full vol-
ume on the preamplifier), a short circuit or an accidentally grounded
speaker output
(see p. 7, detail 2) . Moreover, the unit turns off after
an interruption of the power supply.
In any case, wait at least one minute before trying to restart
the TEM 3200.
If the protective switch engages immediately after restarting, switch
off the amplifier and contact your dealer or distributor.
Problem: The TEM 3200 doesn’t power up or power-up
seems to last forever.
Cause:
To ensure a long tube life the TEM 3200 is fitted with a soft-
start circuit. Tube heating and voltage are engaged very slowly while
performing several parameter checks. This process, which may last
up to 3 minutes, waits until all values are within the specifications until
it activates the outputs.
If power-up takes notedly more than 3 minutes, check whether the
overload protection is enabled (see above). Otherwise, please con-
tact your dealer or distributor.
