SYSTEM CONNECTION DIAGRAM 2:
Multiple Fathoms to
Home Theater Receiver or
Home Theater Preamp/Processor
To greatly simplify using multiple
subwoofers in a single home theater
system, Fathoms incorporate a
“Master/Slave” signal distribution system.
Th
is allows control of all the Fathoms in a
system from a single “Master” unit.
First, you will select one of the Fathom
subwoofers as the “Master” via its upper
“Input Mode” switch. Generally, you
will designate the Fathom closest to the
receiver/preamp as the master. In some
cases; for example, when the control panel
of certain units is diffi
cult to access, you
may prefer to designate the one which is
easiest to access as the master.
Two connection types are available
for connecting the master Fathom to your
home theater system: balanced (XLR or
1/4-inch TRS connector) and unbalanced
(RCA-type connector). Balanced
connections provide superior noise
rejection and ensure proper grounding
between components. If your receiver or
processor has balanced outputs, we highly
recommend that you use them to connect
to the Fathom designated as the master.
In the connection diagram at left ,
balanced connections are shown as solid
lines, unbalanced connections are shown
dotted. You will only use one of these
input connection methods for the Fathom
designated as the master (not both).
Th
e remaining Fathoms in the system
will be confi gured as “Slave” units via
their upper “Input Mode” switches.
Using balanced XLR cables, you will
connect the master Fathom’s “Output to
Slave” to the “Left or Mono” balanced
input of the fi rst slave Fathom. Th
at
slave unit’s “Output to Slave” connector
will feed the “Left or Mono” input of
the next slave unit via another balanced
XLR cable. Subsequent slave units will
be connected in the same manner.
Connections between the “Master” and
“Slave” Fathoms and between “Slave”
Fathoms are via balanced XLR cables ONLY.
