If used with an analogue signal, connect the interconnect between the preamp and
each power amp. Check the input switch is in the analogue position.
You may either use the analogue input RCA female socket or the XLR. The XLR
socket, especially useful in professional installations, is wired as follows :
1 - Grounding, Shielding.
2 - Hot.
3 - Cold.
Attention : if you want to use a symmetrical 4 wire cable, always maintain the
ground/earth switch to "Link" or you may destroy your amplifier.
When used with a digital input signal, connect the digital input cable to the digital
input and switch the input switch to digital. Since a digital Spdif cable carries 2
channels you may link the digital output to the next amplifier to transfer the second
channel.
Connect the speaker cable to one of the red and black terminals in the back of the
amplifier or, if you use a Goldmund High Definition Speaker Cable, to the coaxial
connector.
The 2 separate outputs are connected internally in parallel.
You may notice that the ground of the input plug and the black speaker terminal are
the same polarity. The amplifier is non-inverting in phase.
5 – AMPLIFIER CONTROLS
On the front panel of the GOLDMUND MIMESIS 18.4 amplifier you will find only the
power key and 3 Led.
To start playing the amplifier, switch the key to ON. The amplifier is immediately
operative, without delay and the central green Led indicates it is operating normally.
The Mimesis 18.4 is using a signal-sensing auto-start circuit. If no modulation is
received by the power amp for approximately 20 minutes, the power amp will go off
and the green central Led will only flash regularly to indicate that the amp is ON and
ready to restart.
If a signal is applied to the input (analogue or digital), the amp will start working again
and the green Led will stay on.
In large system with several amplifiers connected, you may have problem when
applying a signal if all power amps start simultaneously, triggering the house breaker.
To avoid it, each amp may have a small different delay adjusted to make them start
in sequence and avoid the problem. To adjust each amp differently, disconnect the
amplifier from AC, open the bottom removable plate, and using a small screwdriver,
turn the small rotary switch accessible on the visible printed circuit. Just set each
amp to a different position of the switch.
