PROTECTION AGAINST HF OSCILLATIONS
In the same way, the speaker must be protected against a large amount of high frequency
oscillations, 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 250+ 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.
7.3
OVERHEATING PROTECTION
If for any reason (malfunction, too high level, too low load impedance) the temperature of
the amplifier could reach a dangerous level and the TELOS 250+ could be damaged.
To avoid this type of damage, if the temperature rises too high, a protection circuit switches
the amplifier OFF automatically. The red front panel will be lit indicating that the amplifier
has been turned OFF by the protection circuit.
If this happens, let the amplifier cool for some time. We strongly recommend investigating
the cause of the temperature gain before operating the amplifier again.
