We recommend that you proceed carefully to try this. You must do it in combination
with the speaker polarity and/or with absolute phase switching to be sure of the
result.
- The GOLDMUND exclusive "Mechanical grounding".
In the GOLDMUND MIMESIS 29.4 amplifier, GOLDMUND has, more than in any
other of its components, fully implemented an optimized vibration evacuation path.
This is called by GOLDMUND : "Mechanical Grounding". The perfect adjustment of
this evacuation provides the MIMESIS 29.4 with an extraordinary dynamic capability
and transparency, especially on low efficiency speakers.
To get all the benefits of this design, the MIMESIS 29.4 must be located on a very
rigid support, or better directly on the floor, to be directly coupled with the building
rigid construction. Try various location until you find the most rigid one. Avoid any
decoupling material, carpet especially, even between the furniture and the floor. Use
the four pin-point feet to couple the amplifier to the supporting furniture or to the
floor.
With a very top system, the sonic improvement when the proper grounding is found
is obvious and worth the try.
7 – SAFETY FEATURES
The GOLDMUND MIMESIS 29.4 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 29.4 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.
In such a case, the DC protection circuit of the MIMESIS 29.4 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 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 :
