GOLDMUND MIMESIS 27.5 - Analog Preamplifier - 8 

FRONT & BACK PANELS FUNCTIONS

 

 

 

POWER 

On the back panel of the Goldmund Mimesis 27.5 preamplifier the switch is used to power 
on the preamplifier. In regular use, this switch is left ON and the circuits of the preamplifier 
are left ON. The standby function of the remote control is only shorting the output to ground 
for safe removal of the cables to the power amplifier.  
 
The preamp can be powered off by switching the switch to the OFF position. A special 
safety circuit switches the preamp to muting, to avoid any disturbance to reach the power 
amplifier and the speakers, even if the preamplifier is disconnected from the AC plug by 
accident. 
However, to optimize the sound quality of the preamplifier and insure the best reliability, 
Goldmund recommends that the unit is left powered ON. 

 

MUTING 

Muting is controlled from the remote control. It can be used to temporarily turn the volume 
down without touching the volume control. When returned to normal, the level of the 
preamplifier is returned to where it was when the muting was activated.  
 

VOLUME 

May be adjusted manually by turning the volume control or on the remote by  or 
-. 

 
SELECTOR 

Selects one of the available input for listening (8 if D/A option is enabled, 5 if not), including 
the one tape inputs for monitoring. A step clockwise is selecting the next input; a step 
counterclockwise selects the previous input. A display on the front panel shows the number 
of the input selected. Selection may be also made on the remote by pressing the key 
corresponding to the input on the Analog section of the remote.  

 

RECORD 

Record is factory set. Tape in is always input 5. If input 5 is selected, tape out is 
disconnected. Otherwise, tape out is connected to the selected input. E.g. input 3 is 
selected, so tape out receive signal from input 3.
