- 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
become 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 28 may be
damaged. If the temperature rises too high, switch the amp off for quite some time. It
is strongly recommended to try to detect why the temperature has reached such a
level before operating the amp again.
- Protection against short-circuits.
If one output is short-circuited by accident and the current becomes too high, the AC
fuse may blow.
To replace the defective fuse, switch the amplifier off first. Then open the small
drawer located on the AC cord receptacle. The fuses are located inside. Change the
defective fuse.
Then switch the power on if the short-circuit has been detected and removed.
To avoid the fuses to blow, avoid to short-circuit the output terminals accidentally.
Always switch OFF the amp before trying any manipulation of the speaker cables.
There is no risk to leave the speaker terminals unconnected when the amp is on.
8 - MAINTENANCE
The GOLDMUND MIMESIS 28 amplifier usually requires no maintenance. For audio
purists who want to keep their amp sounding as new, we only recommend that after
a year or two, you have a technician or an official GOLDMUND representative
readjust the DC offset. This very simple operation takes only two minutes and will
give you the safety of long years of unmatched sound quality.
