The GOLDMUND TELOS 200 amplifier provides features to protect the amplifier and the
speakers against all mishandling or component failure. However precautions must be taken
to avoid problems with a very high power amplifier.
Protection against DC
The TELOS 200 is a DC-coupled amplifier. If the associated preamplifier is badly designed or
defective (often true for tube preamps), the speakers could be damaged.
In such a case, the DC protection circuit of the TELOS 200 will automatically turn off the
amplifier. This detection circuit is totally immune to any sonic effect.
To indicate that the amplifier has been turned off by the protection circuit, a red Led will be
displayed on the front panel.
When the source of DC offset is suppressed, turn ON the amplifier again.
Protection against HF oscillations
In the same way, the speaker must be protected against a large amount of high frequency
oscillation, if present, before and after to avoid any danger for the tweeters, even if these
frequencies remain unnoticed.
The amplifier is by itself extremely stable. However some mishandling must be avoided in
order to avoid any oscillation:
• Never plug an input cable into a power amp when it is turned on.
• Be careful to use only very high quality interconnects. If the ground connection becomes
loose, there is a big danger of oscillation. Warranty is voided if this occurs.
• Never run the input and output (speaker) cables in parallel.
If the TELOS 200 detects excessive oscillation, the amplifier will be turned OFF automatically.
You will have to suppress the source of oscillation and turn it ON again once the protection
is activated.
