SAFETY FEATURES

The GOLDMUND MIMESIS 29M amplifier provides sophisticated features to
protect the amplifier and the speakers against all mishandle or component
failure. However precautions must be taken to avoid problems with a very high
power amplifier.
- Protection against DC.
The MIMESIS 29M is a DC-coupled amplifier. If the associated preamplifier is
badly designed or defective (often true for the tube preamps), the speakers could
be damaged. The DC protection circuit of the MIMESIS 29M is totally immune to
any sonic effect but will protect the speakers if such a malfunction occurs.
- Protection against HF oscillations.
In the same way, the speaker must be protected against a large amount of high
frequency oscillation if present 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 on 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 parallel.
- Overheating protection.
If for any reason (malfunction, too high level, too low load impedance) the
temperature of one channel reaches a dangerous level, the MIMESIS 29M may
be damaged.
