Mini Mixer  
Model MN04 Owner's Manual  
Thank you for purchasing the Fostex Model MN04.  
The model MN04 is a four input two output mini mixer small in size and light in weight.  
Channel 1 is an input for line/mic level (switchable type) and channels 2~4 are inputs for line level  
signals.  
Channel 1, in particular, has, in addition to the regular mic level position, an ALC (Automatic Level Control)  
circuit position which minimizes distortion against input overload when using a microphone.  
The MN04 can be conveniently used in any location as it employs a two power supply system (AC adaptor  
[Included]/S-006P battery [Option]). Please read through this manual before operation.

<NOTE>  
Be sure to remove the battery if it  
is not to be used for long hours or  
extensive periods of time. If not,  
it could result in leaking electrolyte  
from the battery which can ruin  
your new mixer.  
<NOTE>

Unplug the AC adaptor from the wall outlet if the MN04 is not to be  
used for long hours or extensive periods of time.  
INTERCONNECTING EXAMPLE WITH EXTERNAL EQUIPMENT  
As shown in example below, by interconnecting MN04 as a sub mixer with a multitracker having few input ports, a multitude of sound sources  
can then be mixed and recorded by the multitracker.
