GOLDMUND Telos 280 – ANALOG POWER AMPLIFIER - 9

SAFETY AND PRECAUTIONS
Protection of the circuit
The Goldmund Telos 280 is a DC-coupled amplifier without protection. If it is associated
with a badly designed or defective analog preamplifier (often true for tube preamplifiers
and some 5 channel processors) the speakers could easily be damaged by the DC.
The Telos 280 doesn’t amplify DC but DC applied at the input is passed to the output.
This protection circuit is totally transparent and has no sonic effect.
If one output is short-circuited by accident, the amplifier will source too much current.
Such accident should be limited over time to avoid excessive heat build-up occurring.
This is not covered by the warranty.

MAINTENANCE
The Goldmund Telos 280 amplifier usually requires no maintenance.
To clean your amplifier, use a very soft, clean, damp cloth to avoid scratching the
surface. Dampen with water or a mild detergent solution. Avoid abrasive or harsh
cleansers (e.g. products containing sodium carbonate).
Always turn the power OFF before cleaning your amplifier.
ATTENTION: the Goldmund Telos 280 is an
extremely high speed amplifier.
Any bad ground connection can generate high
frequency oscillation which is dangerous for
tweeters.
It is also generally dangerous to run analog input
cables and speaker cables in parallel for a long
distance. If these cables are not of high quality or
badly shielded, an “Antenna-Effect” can generate
dangerous high-frequency oscillations.
