All  channels  feature  a  lever  switch  input  selector,  independent  gain  control  for  each 
channel and 3-band tone controls  with semiparametric adjustment for the mid-band. 
(Center frequency adjustable, fixed Q) 

All inputs are PFL capable in order to visually (through the VU meters) and acoustically 
(through headphones) monitor any signal connected to the inputs of the unit. 

 

INSTALLATION 

5.1. Placement and mounting 

The first thing to take into account when looking for the placement of the COMPACT 8 
is your comfort and an easy access to all the connections. 

The COMPACT 8 has 19" (482.6mm), 4U (177mm) rack mounting ears that allow you to 
place it in a standard rack. 

Because of the high gain of the PHONO and MIC inputs, the mixer must be placed as far 
as possible from noise sources (dimmers, engines, etc.) as well as from any mains cable. 
You should never, under any circumstance, remove the metallic cover of the mixer. 

The COMPACT 8, being a low consumption unit, does not need any cooling; you should 
anyway avoid exposure to extreme temperatures and the operating environment must 
be as dry and dust free as possible. 

The COMPACT 8 operates under voltages between 90 and 264 V at 47 to 63 Hz. This 
device features an over dimensioned power supply that adapts to the mains voltage in 
any country of the world with no need to make any adjustments. 

In order to protect the mixer from eventual mains overloads, it has a time-lag 0,5 A (32) 
mains protection fuse. Should this fuse ever blow off, disconnect the mixer from mains 
and replace it with an identical one. 

NEVER REPLACE THE FUSE WITH ANOTHER ONE 

WITH A HIGHER VALUE.

 

ATTENTION:

 Changing the fuse must be performed by qualified technical 

personnel.
