Samson DB1500A Manuale Utente

Before you start plugging in cables, you should take a minute to decide how you want to interface your new subwoofer. 
There are several ways you can interface the dB1500a and dB1800a, however most systems set-ups fall into two catego-
ries, Stereo or Mono (Common) sub operation.

In larger rooms, as well as in theatres 
and theme park installations (for low 
frequency special audio effects), two 
dB1500a and dB1800a’s can be used 
in stereo.

In most cases a common sub, or mono bass 
operation is desired. This is true for several 
reasons, but mostly because low frequencies 
produced by a subwoofer tend to be non-
directional.  Since low frequency waves take 
so much space to actually develop,  you can’t 
tell if the sub bass is coming from the left or 
right side, unless of course you’re in a very 
large room.  Because of this phenomena, just 
about all sub bass material is mixed in mono.
